2.1 Safety Instructions

l Only properly qualified personnel are permitted to carry out activities such as
transport, installation, commissioning and maintenance. Properly qualified per-
sons are those who are familiar with the transport, assembly, installation, com-
missioning and operation of the product, and who have the appropriate qualifi-
cations for their job. The qualified personnel must know and observe the
following standards and regulations:
IEC 364 and CENELEC HD 384 or DIN VDE 0100
IEC Report 664 or DIN VDE 0110
national accident prevention regulations or BGV A3
l Read this documentation before carrying out the installation and commissio-
ning. Incorrect handling of the servo amplifier can lead to personal injury or
material damage. It is vital that you keep to the technical data and information
on connection requirements (nameplate and documentation).
l Discharge your body before touching the servo amplifier. The servo amplifiers
contain electrostatically sensitive components which may be damaged by in-
correct handling. Avoid contact with highly insulating materials (artificial fab-
rics, plastic film etc.). Place the servo amplifier on a conductive surface.
l The manufacturer of the machine must produce a hazard analysis for the ma-
chine and take appropriate measures to ensure that unforeseen movements do
not result in personal injury or material damage.
l Do not open or touch the equipment during operation. Keep all covers and ca-
binet doors closed during operation. Touching the equipment is allowed du-
ring installation and commissioning for properly qualified persons only. Other-
wise, there are deadly hazards, with the possibility of death, severe injury or
material damage.
— During operation, servo amplifiers may have uncovered live
components, depending on their level of enclosure protection.
— Control and power connections may be live, even though the
motor is not rotating.
— Servo amplifiers may have hot surfaces during operation.
Surface can reach temperatures above 80°C.
l Never undo any electrical connections to the servo amplifier while it is live.
There is a danger of electrical arcing with damage to contacts and personal in-
jury.
Wait at least five minutes after disconnecting the servo amplifier from the main
supply power before touching potentially live sections of the equipment (e.g.
contacts) or undoing any connections. Capacitors can still have dangerous
voltages present up to five minutes after switching off the supply power. To be
sure, measure the voltage in the DC Bus link and wait until it has fallen below
40V.

Technical description 02/06 Beckhoff
2.2 Use as directed

The servo amplifiers are components which are built into electrical equipment or machi-
nes, and can only be commissioned as integral components of such equipment.
The manufacturer of the machine must produce a hazard analysis for the machine
and take appropriate measures to ensure that unforeseen movements do not result
in personal injury or material damage.
The servo amplifier should only be used with power supplies with a maximum
symmetrical rated current of 5000A and a voltage of 115/230V AC (AX250x) or 400V
AC (AX251x).
Mains voltage Servo amplifier

1 x 115V AC only AX250x, unearthed operation is permissible
3 x 230V AC all types, unearthed operation is permissible
3 x 400V AC only AX251x, TN-system or TT-system with earthed neutral point
If the servo amplifiers are used in residential areas, or in business or commercial premi-
ses, then additional filter measures must be implemented by the user.
The AX2500 family of servo amplifiers is only intended to drive specific brushless syn-
chronous servomotors with closed-loop control of torque, speed and/or position. The
rated voltage of the motors must be at least as high as the DC Bus link voltage of the
servo amplifier.
The servo amplifiers may only be operated in a closed control cabinet, taking into
account the ambient conditions defined on page 17. Ventilation or cooling measures may
be required to keep the temperature below 45°C.
Use only copper-cored cables for wiring. The conductor cross-sections can be taken from
the European standard EN 60204 (or Table 310-16 of NEC for 60°C or 75°C in the
column for AWG cross-sections).
We can only guarantee that the system will conform to the standards cited on page 9 if
the components used are exclusively those supplied by us (servo amplifier, motor, cables
etc.).

2.3 European Directives and Standards

Servo amplifiers are components that are intended to be incorporated into electrical plant
and machines for industrial use. When the servoamplifiers are built into machines or
plant, the intended operation of the amplifier is forbidden until it has been established that
the machine or plant fulfills the requirements of the EC Machinery Directive 98/37/EG and
the EC Directive on EMC (89/336/EEC) and the Low Voltage Directive 73/23/EEC.
To fulfill the EC Machinery directive 98/37/EG, the following standards have to be applied:
EN 60204-1 (Safety and electrical equipment of machines)
EN 292 (Safety of machines)
The manufacturer of the machine must produce a hazard analysis for the machine
and take appropriate measures to ensure that unforeseen movements do not result
in personal injury or material damage.
To fulfill the Low Voltage Directive 73/23/EEC, the following standards have to be applied:
EN 60204-1 (Safety and electrical equipment of machines)
EN 50178 (Equipment of high voltage plant with electronic devices)
EN 60439-1 (Low-voltage switchgear and controlgear assemblies)
To fulfill the EC EMC regulations 89/336/EEC, the following standards have to be applied:
EN 61000-6-1 or EN 61000-6-2 (noise immunity in the domestic range/industrial range)
EN 61000-6-3 or EN 61000-6-4 (noise emission in the domestic range/industrial range)
The manufacturer of the machine or plant is responsible for ensuring that they meet the
limits required by the EMC regulations. Advice on the correct installation for EMC – such
as shielding, grounding, arrangement of connectors and cable routing – can be found in
this documentation.
The machine / plant manufacturer must examine whether with its machine / plant
still further or other standards or EEC guidelines are to be used.
2.4 CE Conformity
Conformity with the EC Directive on EMC 89/336/EEC and the Low Voltage Directive
73/23/EEC is mandatory for servoamplifiers supplied within the European Union.
To fulfill the EMC directive, the standard EN 61800-3 is applied.
In the reference to noise immunity the servoamplifier fulfills the requirement to the cate-
gory second environment (industrial environment). For noise emission the amplifier meets
the requirement to a product of the category C2 (motor cable £ 25m).
Warning!
This product can cause high-frequency interferences in non industrial
environments which can require measures for interference suppression.
The servo amplifiers have been tested by an authorized testing laboratory in a defined
configuration with the system components which are described in this documentation.
Any divergence from the configuration and installation described in this documentation
means that you will be responsible for carrying out new measurements to ensure that the
regulatory requirements are fulfilled.
To fulfill the Low Voltage Directive, the standard EN 50178 has to be applied.

2.5 UL and cUL- Conformance

This servo amplifier is listed under UL file number E217428.
UL (cUL)-certified servo amplifiers (Underwriters Laboratories Inc.) fulfil the relevant U.S.
and Canadian standard (in this case UL 840 and UL 508C).
This standard describes the fulfilment by design of minimum requirements for electrically
operated power conversion equipment, such as frequency converters and servo ampli-
fiers, which is intended to eliminate the risk of fire, electric shock, or injury to persons,
being caused by such equipment.
UL(cUL) regulations also specify the minimum technical requirements of electrical devi-
ces, in order to take the necessary measures against the risk of fire, which can be trigge-
red by electrically operated devices. The technical conformance with the U.S. and Cana-
dian standard is determined by an independent UL (cUL) inspector through the type
testing and regular checkups.
Apart from the notes on installation and safety in the documentation, the customer does
not have to observe any other points in direct connection with the UL (cUL)-certification of
the equipment.
UL 508C
UL 508C describes the fulfilment by design of minimum requirements for electrically ope-
rated power conversion equipment, such as frequency converters and servo amplifiers,
which is intended to eliminate the risk of fire being caused by such equipment.

Following EN 60204-1, we recommend :
AC connection 1.5 mm², depending on the system fusing
Motor cables, max. 25m 1 mm², shielded, capacitance <150pF/m
Resolver, motor thermostat, 4x2x0.25 mm², twisted pairs, shielded,
max.100m capacitance <120pF/m
Encoder, motor thermostat, 7x2x0.25 mm², twisted pairs, shielded,
max. 50m capacitance <120pF/m
Analog signals 0.25 mm² , twisted pairs, shielded
Control signals, BTB, DGND 0.5 mm²
Holding brake (motor) 0.75 mm², shielded, check voltage drop
+24 V / XGND max. 2.5 mm², check voltage drop

2.10 Motor holding brake control

A motor holding brake (max.1.5A) can be controlled directly by the servo amplifier.
Check voltage drop, measure the voltage at brake input and check brake function
(brake and no brake).
This function does not ensure personnel safety!
The brake function must be enabled through the BRAKE parameter (on the screen page
for Motor): the setting is WITH.
In the diagram below you can see the timing and functional relationships between the
ENABLE signal, speed setpoint, speed and braking force.
During the internal enable delay time of 100ms the speed setpoint of the servo amplifier is
internally driven down a 10ms ramp to 0V. The brake output is switched on when 3% of
the final speed is reached, at the latest after 1 second.
The rise (fbrH) and fall (fbrL) times of the holding brakes that are built into the motors vary
for the different types of motor (see motor manual).
A description of the interface can be found on page 39.
Personnel-safe operation of the holding brake requires an additional “make” contact in
the brake circuit and a spark suppressor device (e.g. a varistor) in the recommended
brake circuit:
AX25

2.11 Regen circuit

During braking with the aid of the motor, energy is fed back to the servo amplifier. This
energy is converted into heat in the regen resistor. The regen resistor is switched in and
out by the regen circuit. The switching thresholds for the regen circuit are adjusted to suit
the supply voltage with the aid of the setup software.
Our customer support can help you with the calculation of the regen power which is requi-
red. A description of the interface can be found on page 39 .
Internal regen resistor 33 W

External regen resistor (ð p.71) 33 W
Functional description
The regen circuit starts to respond when the DC Bus link voltage reaches the set value.
If the energy which is fed back from the motor, as an average over time or as a peak
value, is higher than the preset regen power, then the servo amplifier will output the sta-
tus regen power exceeded and the circuit will be switched off.
At the next internal check of the DC Bus link voltage (after a few milliseconds) an overvol-
tage will be detected and the servo amplifier will be switched off, with the error message
overvoltage (ð p.66).
The BTB/RTO contact (terminals X1/1,2) will be opened simultaneously (ð p.49).

The electrical isolation is indicated in the block diagram (ð p.37).

2.13 Switch-on/-off behaviour

The diagram below illustrates the correct functional sequence for switching the servo
amplifier on and off.
2.13.1 Stop function as per EN 60204 (VDE 0113)
If a fault occurs (ð p.66), the output stage of the servo amplifier is switched off and the
BTB/RTO contact is opened. In addition, a global error signal can be given out at one of
the digital outputs (terminals X3/8 and X3/9) (see the Online help in the setup software).
These signals can be used by the higher-level control to terminate the current PLC cycle
or to shut down the drive (through an additional brake or similar means).
Instruments with a selected Brake function use a special sequence for switching off the
output stage (ð p.18). The Stop functions are defined in EN 60204 (VDE 0113), Paras.
9.2.2 and 9.2.5.3.
Categories of Stop functions
Category 0: Shut down by immediate switch-off of the supply of energy to the
drive machinery (i.e. an uncontrolled shut-down)
Category 1: A controlled shut-down, during which the supply of energy to the
drive machinery is maintained to perform the shut-down, and where
the supply is only interrupted when standstill has been reached
Category 2: A controlled shut-down, where the supply of energy to the drive
machinery is maintained
Every machine must be equipped with a Stop function to Category 0.
Categories 1 and/or 2 must be provided if the safety or functional requirements of the
machine make this necessary.
Implementation of the Stop function :
You can find wiring recommendations in our application note
“Stop and Emergency Stop functions"

2.13.2 Emergency stop methods
The Emergency Stop function is defined in EN 60204 (VDE 0113), Para. 9.2.5.4.
In addition to the requirements for Stop, the Emergency Stop must fulfill the following
requirements:
l it must have priority over all other functions and controls in all operating situations
l the energy supply to any drive machinery that could cause dangerous situations
must be switched off as fast as possible, without causing any further hazards (e.g. by
using
mechanical latching devices that do not require an external supply of energy, by
counter-current braking in Stop Category 1)
l the reset must not initiate a restart
If necessary, provision must be made for the additional connection of emergency stop
devices (see EN 60204 Requirements for emergency stop devices).
The Emergency Stop must be effective as a stop of either Category 0 or Category 1.
The Emergency Stop Category must be determined by a risk evaluation of the machine.
Category 0
Only hard-wired electromechanical components may be used for an Emergency Stop
function to Category 0. The action must not depend on switching logic (hardware or soft-
ware) or on the transmission of commands through a communications network or a data
connection.
In multi-axis systems using a coupled DC Bus link the motor cable must also be discon-
nected by a changeover switch (a contactor, such as Siemens type 3RT1516-1BB40) and
short-circuited by resistors wired in a star configuration.
Category 1
For Emergency Stop Category 1 the final disconnection of the energy supply to the drive
machinery must be ensured by electromechanical components. Supplementary Emer-
gency Stop devices may be plugged in.

3.1 Important notes

l Protect the servo amplifier from impermissible stresses. In particular, do not let any
components become bent or any insulation distances altered during transport and
handling. Avoid contact with electronic components and contacts.
l Check the combination of servo amplifier and motor. Compare the rated voltage and
current of the units. Carry out the wiring according to the instructions on page 27.
l Make sure that the maximum permissible rated voltage at the terminals for L1, L2, L3
and +RBext, –DC is not exceeded by more than 10%, even in the most unfavourable
conditions (see EN 60204-1 Section 4.3.1). An excessive voltage on these terminals
can lead to destruction of the regen circuit and the servo amplifier.
Use the AX251x only on an earthed 3-phase supply system. Use the amplifier only to
drive a synchronous servomotor.
l The fusing of the AC supply input and the 24V supply is installed by the user
(ð p.16).
l Take care that the servo amplifier and motor are properly earthed. Do not use pain-
ted (non-conductive) mounting plates.
l Route power and control cables separately. We recommend a separation of at least
20 cm. This improves the interference immunity required by EMC regulations. If a
motor power cable is used which includes cores for brake control, the brake control
cores must be separately shielded. Earth the shielding at both ends (ð p.28).
l Install all heavy-current cables with an adequate cross-section, as per EN 60204-1
(ð p.17) and use the requested cable material (ð p. 33) to reach max. cable length.
l Wire the BTB/RTO contact in series into the safety circuit of the installation.
Only in this way is the monitoring of the servo amplifier assured.
l Install all shielding with large area (low impedance) connections, with metallised con-
nector housings or shield connection clamps where possible.
Notes on connection techniques can be found on page 32.
l Ensure that there is an adequate flow of cool, filtered air into the bottom of the control
cabinet or use heat exchanger. Note the conditions on page 17 .
l It is permissible to alter the servo amplifier settings by using the operator software.
Any other alterations will invalidate the warranty.
Caution
Never disconnect the electrical connections to the servo amplifier while it is live.
Residual charges in the capacitors can have dangerous levels up to 300 seconds
after switching off the mains supply voltage. Measure the voltage in the DC Bus
link (+RBext/-DC) and wait until the voltage has fallen below 40V.
Control and power connections can still be live, even when the motor is not
rotating.

3.4 Wiring
Only professional staff who are qualified in electrical engineering are allowed to
install the servo amplifier.
The installation procedure is described as an example. A different procedure may be
appropriate or necessary, depending on the application of the equipment.
We provide further know-how through training courses (on request).
Caution !
Only install and wire up the equipment when it is not live, i.e. when neither the
mains power supply nor the 24 V auxiliary voltage nor the operating voltages of
any other connected equipment is switched on.
Take care that the cabinet is safely disconnected (lock-out, warning signs etc.).
The individual voltages will be switched on for the first time during commissioning.
The ground symbol X , which you will find in all the wiring diagrams, indicates
that you must take care to provide an electrically conductive connection with the
largest possible area between the unit indicated and the mounting plate in the
control cabinet. This connection is for the effective grounding of HF interference,
and must not be confused with the PE symbol W (protective earth to EN 60204).

3.5 Setup software
3.5.1 General
This chapter describes the installation of the setup software DRIVE.EXE for the AX2500
digital servo amplifiers.
We offer training and familiarization courses on request.
3.5.1.1 Use as directed
The operator software is intended to be used for altering and storing the operating para-
meters for the AX2500 series of servo amplifiers. The attached servo amplifier is commis-
sioned with the assistance of the software - during this process the drive can be control-
led directly by the service functions.
Only professional personnel who have the relevant expertise described on page 5
are permitted to carry out online parameter setting for a drive which is running.
Sets of data which are stored on data media are not safe against unintended
alteration by other persons. After loading a set of data you must therefore check all
parameters thoroughly before enabling the servo amplifier.
3.5.1.2 Software description
The servo amplifiers must be adapted to the requirements of your installation. Usually you
will not have to carry out this parameter setting yourself on the amplifier, but on a PC,
with the assistance of the operator software. The PC is connected to the servo amplifier
by a null-modem (serial, ð p.56) cable. The setup software provides the communication
between the PC and AX2500.
You will find the setup software on the accompanying CD-ROM and in the download sec-
tion of our website.
With very little effort you can alter parameters and immediately observe the effect on the
drive, since there is a continuous (online) connection to the amplifier. At the same time,
important actual values are read out from the amplifier and displayed on the PC monitor
(oscilloscope function).
Any interface modules which may be built into the amplifier are automatically recognized,
and the additional parameters which are required for position control or motion-block defi-
nition are made available.
Sets of data can be stored on data media (archived) and loaded again. You can also print
out the data sets.
We provide you with motor-specific default sets of data for all the reasonable combina-
tions of servo amplifier and motor. In most applications you will be able to use these
default values to get your drive running without any problems.

3.5.1.3 Hardware requirements
The PC interface (X6, RS232) of the master is connected to a serial interface on the PC
by a null-modem cable (not a null-modem link cable !) (ð p.56).
Connect / disconnect the interface cable only when the supply is switched off for
both the PC and the servo amplifier.
The interface in the servo amplifier is electrically isolated by an optocoupler, and is at the
same potential as the CANopen interface.
Minimum requirements for the PC:
Processor : Pentium I or higher
Operating system : WINDOWS 98 / 2000 / ME / NT4.0 / XP
Graphica adapter : Windows compatible, color
Drives : Hard disk (10 MB free space)
CD-ROM drive
Main memory : at least 8MB
Interface : one free serial interface (COM1:, 2:, 3: or 4:)
3.5.1.4 Operating systems
WINDOWS 98 / 2000 / ME / NT / XP
DRIVE.EXE can work under WINDOWS 98 / 2000 / ME / XP or WINDOWS NT 4.0.
Emergency operation is possible with an ASCII terminal-emulation.
Interface setting: 9600 bps, databit 8, stopbit 1,no parity, no handshake

Standard setting: Speed Setpoint
Fixing the direction of rotation
Standard setting: clockwise rotation of the motor shaft (looking at shaft end)
with positive voltage on terminal X3/3 (+ ) against X3/2 ( - )
To reverse the direction of rotation you can swap the connections to terminals X3/2-3 or
change the DIRECTION parameter in the SPEED screen.

4.7.2 Digital inputs (X3)
All digital inputs are electrically isolated through optocouplers.

Technical data
— Reference ground is digital-GND (DGND, terminal X1/4,5 on the master)
— The logic is dimensioned for +24V / 7mA (PLC-compatible)
— H-level from +12...36V / 7mA, L-level from 0...7V / 0 mA
— Update rate: Software:250 µs / Hardware: 2µs
AX2500
You can use the digital inputs PSTOP / NSTOP / DIGITAL-IN1 and DIGITAL-IN2 to
initiate pre-programmed functions that are stored in the servo amplifier.
You will find a list of the pre-programmed functions in the Online Help.
If an input has to be re-assigned to a pre-programmed function, then the data set must be
stored in the EEPROM of the servo amplifier, and the 24V auxiliary supply for the servo
amplifier must be switched off and then on again (to reset the amplifier software).
Limit-switches PSTOP / NSTOP
Terminals X3/6 and X3/7 are used to connect limit switches. They are deactivated upon
delivery. If these inputs are not needed for the connection of limit switches, then they can
be used for other input functions.
Limit-switch positive/negative (PSTOP / NSTOP, terminals X3/6 and X3/7), high level in
normal operation (fail-safe for cable break). A low signal (open) inhibits the corresponding
direction of rotation.
DIGITAL-IN 1 / DIGITAL-IN 2
You can link the digital inputs at terminals X3/4 (DIGITAL-IN 1) and X3/5 (DIGITAL-IN2)
with a pre-programmed function.

4.7.3 Digital outputs (X3)
Technical characteristics
— Ground reference is Digital-GND (DGND, terminal X1/4,5 on the master)
— Alle digital outputs are floating
— DIGITAL-OUT1 and 2 : Open-collector, max. 30V DC, 10mA

(terminal X3/9) to output messages from pre-programmed functions that are stored in the
servo amplifier.
A list of the pre-programmed functions can be found in the Online Help.
If an input is freshly assigned to a pre-programmed function, then the data set must be
stored in the EEPROM of the servo amplifier, and the 24V auxiliary supply of the servo
amplifier must be switched off and on again (to reset the amplifier software).

4.7.4 Digital I/O on the Master (X1)
Technical characteristics
— Ground reference is Digital-GND (DGND, terminal X1/4,5)
— The logic is dimensioned for +24V / 7mA (PLC-compatible)
— H-level from +12...36V / 7mA, L-level from 0...7V / 0 mA
BTB/RTO: Relay output, max. 30V DC or 42V AC, 0.5A
AX2500
ENABLE input
The output stage of the servo amplifier is activated by the enable signal
(terminal X1/3, input 24V, active-high).
In the inhibited state (low signal) the motor which is attached does not have any torque.
Ready-to-operate contact BTB/RTO
Operational readiness (terminals X1/1 and X1/2 ) is signalled via a floating relay contact.
The contact is closed when all servo amplifiers in the system are ready for operation.
This signal is not influenced by the enable signal, the I²t- limit, or the regen threshold.
All faults cause the BTB/RTO contact to open and the switch-off of the output
stage (if the BTB contact is open, the output stage is disabled -> no power). A list
of the error messages can be found on page 66.

4.8 Encoder emulations
4.8.1 Incremental encoder output - A quad B (X4)
The incremental-encoder interface is part of the package supplied. Select the encoder
function ROD (screen page “Encoder”, funktion ENCMODE). In the servo amplifier, the
position of the motor shaft is calculated from the cyclic-absolute signals of the resolver or
encoder.
Incremental-encoder compatible pulses are generated from this information. Pulses are
output as two signals, A and B, with 90° phase difference and a zero pulse. The resolu-
tion (lines before quadrature) can be changed with the RESOLUTION parameter:
Encoder function Feedback system Resolution Zero position

one per revolution
Resolver 16...1024
(only if A=B=1)
ROD (1)
16...4096 and one per revolution
EnDat / HIPERFACE

Incremental encoders w/o 4...128 (2n) TTL analog pass
ROD interpolation (3)
absolute data channel lines per sine line through X2 to X4
You can also adjust and store the position of the zero pulse within one mechanical turn
(parameter NI-OFFSET). The ground reference for the interface is PGND.
PGND must always be connected to the control ground. The max. admissible cable
length is 10 m.
Connections and signal description for the incremental-encoder interface :

The count direction is UP when the motor shaft is rotating clockwise (looking at the end of
the motor shaft).
AX2500

4.8.2 SSI output (X4)
The SSI interface (synchronous serial absolute-encoder emulation) is part of the package
supplied. Select encoder function ROD (“Encoder” screen page).
The servo amplifier calculates the motor shaft position from the cyclic-absolute signals of
the resolver or encoder. From this information a SSI date (after Stegmann patent specifi-
cation DE 3445617C2) is provided.
28 bits are transferred. The 12 leading data bits contains the number of revolutions. The
following max. 16 bits contain the resolution and are not variable.
The following table shows the allocation of the SSI date:
Revolution Resolution
11 10 9 8 7 6 5 4 3 2 1 0 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0
The signal sequence can be output in Gray code or in Binary (standard) code (parameter
SSI-CODE). The servo amplifier can be adjusted to the clock frequency of your SSI-eva-
luation through the SSI-TIMEOUT parameter (cycle time 1.3 µs or 10 µs).
The ground reference for the interface is PGND.
PGND must always be connected to the control ground.
Connection and signals for the SSI interface :

The count direction is UP when the motor shaft is rotating clockwise (looking at the end of
the motor shaft).

4.9 Master-slave operation, encoder master control

This interface can be used to link several AX2500 amplifiers in master-slave operation.
The parameters for the slave amplifier are set up with the aid of the setup software (elec-
trical gearing). The resolution (no. of pulses/turn) can be adjusted. The analog setpoint
input is inactive.
AGND (terminal X3/1) must be connected to the ground of the control system!
Observe the limit frequency!

4.10 Interface for stepper motor controllers (pulse/direction)

This interface can be used to connect the servo amplifier to a third-party stepper-motor
controller. The parameters for the servo amplifier are set up with the aid of the setup soft-
ware (electrical gearing). The number of steps can be adjusted, so that the servo ampli-
fier can be adjusted to the pulse/direction signals of any stepper-motor controller. Various
monitoring signals can be output. The analog input is inactive.
Observe the limit frequency!

4.10.2 Connection to a stepper motor controller with 24V signal level (X3)
You can use this interface to connect the servo amplifier to a stepper motor control with a
24V signal level. The digital inputs DIGITAL-IN 1 and 2 on connector X3 are used for this
purpose.
Limit frequency: 100 kHz
AX2500

4.11 RS232 interface, PC connection (X8), master only

The setting of the operating, position control, and motion-block parameters, can be car-
ried out by using the setup software on an ordinary commercial PC.
Connect the PC interface (X8) of the servo amplifier while the supply to the equipment
is switched off via a null-modem cable to a serial interface on the PC (do not use a
null-modem link cable!).
The interface has the same potential as the internal logic, and uses AGND as the ground
reference.
The interface is selected and set up in the setup software.
Further notes can be found on page 34 .

(View: front view of the built-in SubD connectors, this corresponds to looking at the solder
side of the SubD connector on the cable.)

4.12 Fieldbus connection
4.12.1 CANopen interface (X7)
The interface for connection to the CAN bus (default: 500 kbps). The master is fitted with
a CAN input. All axis modules in the system are connected to this through the internal
bus. The last axis module has a CAN output, where the CAN bus either continues to
other bus participants or is terminated by a termination resistor.
The integrated profile is based on the communication profile CANopen DS301 and the
drive profile DS402. The following functions are available in connection with the integra-
ted position controller: Jogging with variable speed, homing, start motion task, start direct
task, digital setpoint provision, data transmission functions and many others.
Detailed information can be found in the CANopen manual.
The interface is at the same potential as the internal logic, and uses AGND as the ground
reference.
AGND must be connected to the control system ground for potential equalization!
AX2500
CAN bus cable
To meet ISO 11898 you should use a bus cable with a 120 W characteristic impedance.
The maximum usable cable length for reliable communication decreases with increasing
transmission speed. As a guide, you can use the following values which we have measu-
red, but they must not be assumed to be limits:
Cable data: Characteristic impedance 100-120 W
Cable capacitance max. 60 nF/km
Conductor loop resistance 159.8 W/km
Cable length, depending on the transmission rate
Transmission rate / kbps max. cable length / m
1000 20
500 70
250 115
Lower cable capacitance (max. 30 nF/km) and lower lead resistance (loop: 115 W/km)
make it possible to transmit over longer distances.
(Characteristic impedance 150 ± 5W Þ terminating resistance 150 ± 5W).
For EMC reasons, the SubD connector housing must fulfill the following conditions:
— metal or metallized housing
— provision for connecting the cable shielding within the housing,
large-area connections

4.12.2 PROFIBUS interface (X7), option
This section describes the PROFIBUS interface for AX2500.

Information on the range of functions and the software protocol can be found in the
manual “Communication profile PROFIBUS-DP”.
The selection of cables, cable routing, shielding, bus connectors, bus termination and
propagation times are described in the “Setup guidelines for PROFIBUS-DP/FMS” from
PNO, the PROFIBUS User Organization.
AX2500

4.12.3 SERCOS interface (X7), option
This section describes the SERCOS interface of the AX2500. Information on the range of
functions and the software protocol can be found in the manual “IDN Reference Guide
SERCOS”.
For the fiber optic cable connection, only use SERCOS components to the SERCOS
Standard IEC 61491.
4.12.3.1 Light emitting diodes (LEDs)
RT: indicates whether SERCOS telegrams are being correctly received. In the final
Communication Phase 4 this LED should flicker, since cyclical telegrams are being
received.
TT: indicates that SERCOS telegrams are being transmitted. In the final Communi-c
ation Phase 4 this LED should flicker, since cyclical telegrams are being trans-
mitted. Check the stations addresses for the controls and the servo amplifier if:
- the LED never lights up in SERCOS Phase 1 or
- the axis cannot be operated, although the RT LED is lighting up cyclically.
Err: indicates that SERCOS communication is faulty or suffering from interference.
If this LED is very bright, then communication is suffering strong interference, or is
non-existent. Check the SERCOS transmission speed for the controls and the
servo amplifier (BAUDRATE) and the fibre-optic connection. If this LED flickers,
this indicates a low level of interference for SERCOS communication, or the optical
transmitting power is not correctly adjusted to suit the length of cable.
Check the transmitting power of the (physically) previous SERCOS station.
The transmitting power of the servo amplifier can be adjusted in the setup software
DRIVE.EXE on the SERCOS screen page, by altering the parameter
for the cable length.

Beckhoff 02/06 Setup
5 Setup
5.1 Important notes

Only professional personnel with extensive knowledge in the fields of electrical
engineering and drive technology are allowed to setup the servo amplifier.
The procedure for commissioning is described as an example. Depending on the applica-

tion, a different procedure may be appropriate or necessary. In multi-axis systems, com-
mission each servo amplifier individually.
Before setting up, the manufacturer of the machine must produce a hazard
analysis for the machine and take appropriate measures to ensure that unforeseen
movements do not result in personal injury or material damage.
Check that all connection components that are live in operation are safely
protected against bodily contact. The equipment produces potentially lethal
voltages up to 800V.
Never undo the electrical connections to the servo amplifier while it is live.
Capacitors can still have dangerous residual charges up to 300 seconds after
switching off the supply voltage.
The heat sink and front panel of the amplifier can reach temperatures up to 80°C in
operation. Check the heat sink temperature. Wait until the heat sink has cooled
down to 40°C before touching it
If the servo amplifier has been stored for longer than 1 year, then the DC Bus link
capacitors will have to be re-formed.
To do this, disconnect all the electrical connections.
Supply the servo amplifier for about 30 min. from single-phase 230V AC to the
terminals L1 / L2. This will re-form the capacitors.
Further information on commissioning:

The adaptation of parameters and their effects on the control loop behaviour are
described in the online help of the setup software.
The commissioning of the fieldbus interface is described in the corresponding
manual.
We can provide further know-how through training courses (on request).

Optimization optimize the speed, current and position controllers
see commissioning instructions in the corresponding

Commission fieldbus
manual on the CD-ROM

5.3 Parameterization
A default parameter set is loaded into your servo amplifier at the factory. This contains
valid and safe parameters for the current and speed controllers.
A database for motor parameters is stored in the servo amplifier. During commissioning
you must select the data set for the motor that is connected and store it in the servo
amplifier. For most applications these settings will already provide good to very good con-
trol loop characteristics.
An exact description of all parameters and the options for optimizing the control loop cha-
racteristics can be found in the online help of the setup software.
5.3.1 Multi-axis systems
All the axes in a system can be parameterized through the RS232 interface in the master.
To do this, there is an internal connection between the master and the axis modules. The
PC cable only has to be connected to the master.
The internal address assignment is carried out automatically, so that it is only necessary
to set up the basic station address for the master.
PC
Axismodule 1
Axismodule 2
Axismodule 3
Master
COMx
X8 / PC RS232
After changing the station address it is necessary to turn off the 24V auxiliary
supply, and then turn it on again.
Starting at the master, descending addresses are assigned automatically to the axis
modules. The following table shows an example with one master and three axis modules:
Axis Address Remark

Master 10 Master address, set by user
Axis module 3 9
Axis module 2 8 assigned automatically
Axis module 1 7
The highest permitted master address is 128. When choosing the master address,
please consider that at least address 1 will be assigned to the last (leftmost) axis
module.
In CAN and PROFIBUS field bus systems the automatically assigned addresses
must not match the address of other nodes.

5.3.2 Key pad controls and status displays
Two keys are fitted in the operating panel of the master. Here you can enter the basic
address for the system and call up status information on all the axes that are connected.
5.3.2.1 Operating
The two keys can be used to perform the following functions:
Key symbol Functions

press once : go up one menu item, increase number by one
press twice in rapid succession : increase number by ten
press once : go down one menu item, decrease number by one
press twice in rapid succession : decrease number by ten
press and hold right key, then press left key as well :
enters a number, return function
5.3.2.2 Status display on the axis module
Each axis module is fitted with 2 LEDs that provide a quick indication of the instrument
status.

5.4 Error messages

Any errors that occur are shown in coded form by an error number in the LED display on
the front panel. All error messages result in the BTB/RTO contact being opened, and the
output stage of the amplifier being switched off (motor loses all torque). The motor-hol-
ding brake is activated.
