4.4 CONTROLLABLE MOTORS
miniECO drive is full digital and uses some internal algorithms predetermining the exact
parameterization with which the motor is controlled in order to optimize its performance without
any need to set up countless parameters. This feature greatly facilitates the installation of the Drive
significantly reducing the time in setting up the dynamic of the axis.
The drive is only necessary to pairwith the motor for which it was foreseen the use. Every drive
model was parameterized for use with different motors in the factory.
Strictly adhere to the table motor
The motor actually used is selectable via the " d8 " parameter of the configuration file or via local
keyboard.
For some requirements, it is possible to use other motors or the same motors, but with a
different mapping for this purpose: using a specific program called " Motor SET-UP" the
mapping can be customised up to a maximum of 10 motors or 10 mappings.

miniECO/miniECOplus Cap. 5: Mechanical Installation and Size
WARNING
All the mechanical dimensions of miniECO series (Standard or Plus ) are the
same.
Check that the packaging is intact in the original box. Check that the Drive, its Kit
connectors and possible resistance to recovery have not suffered any visible damage during
transport. Otherwise DO NOT connect the Drive and DO NOT use the other components.
ECO2M/ECO2S Drives is planned to be used in fixed installations and on surfaces which are
not in motion. If one needs to mount it on surfaces with strong vibrations, one should take
appropriate measures such as vibration dampers.
ECO2M/ECO2S Drives is mechanically arranged to be assembled to the board of an electrical
panel by means of suitable fastening holes provided on the outer container.

miniECO/miniECOplus Cap. 6: Electrical Intallation
The braking resistor can reach very high temperatures owing to inertial load and machine
cycle, which is why it is essential segregate the braking resistor in a part of the electrical panel
that is not dangerous for the nearby equipment or for the wiring. In some cases, when a high
inertial load and a very short machine cycle are associated, mechanical segregation with
thermal protection alarm are indispensable. With the following formula the dissipated power can be
calculated P= (0.5 × J t × ω 2 × (f) - PL where Jt = total inertia [in Kg m 2 ] ω = angular speed max
[rad/sec], f = frequency of repetition of work cycle [no cycles to sec] PL = Power required to
overcome friction
6 ELECTRICAL INSTALLATION
ECO2M/ECOS drive, having digital control, must necessarily be coupled with a motor which has been
configured; thus, it is essential that this must be carefully done . To this purpose, please check the correct
combination of d8 parameter in table motors.
If coupled with a motor of a different model the drive can show several drawbacks, such as instability,
overheating and deterioration in its performance
WARNING
Do not open the drive enclosure unless authorised by ESA Automation; in any
case, always wait for three minutes after switching off before attempting to
access product.
miniECO drive has terminal blocks and connectors located on the front of the comtainer. These
connections are highlighted in the figure 6.1. The version miniECO Plus has the same terminal
blocks and connectors in the series miniECO Standard and therefore the common connections
described below are used for all models, the additional features hardware relating to miniECO Plus
have additional connectors that are explained in the appendices at the end of this manual

Connector CN5
miniECO2M, miniECO2S drives via CN5 connector is able to provide information of position on
the transducer used on the motor. When using an incremental encoder, output pulses are strictly the
same as the transducer is in electrical characteristics in the number of pulses per revolution
mechanical crankshaft. However, if using a resolver output, pulses are simulated and therefore the
number of pulses per revolution is selectable, with output characteristics similar to an incremental
Encoder.

WARNING: Encoder output
THE Encoder output is provided with a current limitation that helps maintain the output
even against overload or short circuit. This protection however causes a voltage drop on
the outputs as a function of the applied load. With an external load of 1 k and
present a voltage of 3.2 V between one step and its denied (Es A and A\ ), with 100 the
voltage drops to 2V .These values still conform to the specifications RS 422 typical of
the differential outputs.
Connector CN6
The connector CN6 of miniECO standard is the output connector of the signals of Network of field
CN6 connector is used for debugging with "Drive Watcher" software on the installation of the Drive or
for connecting to a field network. Connecting to multiple devices on the field network you pipeline
signals of communication. When connecting many drives, an isolated connection should be implemented
to increase the immunity of the communication to electromagnetic disturbances.
To facilitate the wiring from the connector in the configuration field area network, if
it is necessary to connect more than one drive, it is recommended that you use the
most produced ESA Automation cable " Network Box Module TO ".
Code to order the product: " 09BM06NETA".

interpose a transformer.
miniECO
Below, you can find the size of the transformer and the fuses for protection put in series with the power
supply to the drive.
The connection to 400Vac network must be carried out via an appropriately sized transformer, possibly
with screen between the primary and secondary windings and with primary configuration to triangle. This
is secondary to a star centre to comply with electrical safety standards. This configuration, MUST have
the star centre connected to ground.
If it is not necessary to ground the secondary of the transformer, configurations can also be used with
transformers having the secondary to a triangle, This configuration minimizes the harmonic current and
each drive must be protected by a group of fuses.

The choice of the transformer must be made on the basis of the power required by the motor with which
the drive should be connected, hence we recommend to consult the motor tables. For very heavy uses, it
may be necessary to increase the power of the transformer (20÷30).
With a single transformer you can feed more than one drive in parallel to determine the size we need to
consider whether their operation takes place in contemporary or less and then add up the corresponding
powers.
If more than three drives are used fed with a single transformer, it is appropriate to provide for a soft-start
circuit.
NOTE: - Depending on the connected motor, the drive can also be powered by single-
phase voltage supplied only to L1-L2 terminals .
- If you want to use this opportunity of connecting them directly to 230 V ac , because
on internal drive has the soft start circuit

7. 1 ELECTRICAL SAFETY
Connection to ground
The ground of the drive has the function of ELECTRICAL SAFETY and
ELECTROMAGNETIC COMPATIBILITY. You MUST follow the points listed
under the title ELECTRICAL SAFETY and we strongly recommended you follow
the indications for the conformity of the installation to EMC regulations under the
title ELECTROMAGNETIC COMPATIBILITY
ELECTRICAL SAFETY
1. The section of the ground conductor of the plant MUST be greater than
10 mm² or, if less than this, check that the minimum size is consistent
with local regulations on the safety of your equipment with leakage
currents.
2. The section of the wire from the Drive to the ground point of the electric
panel or to terminal anchored to the bottom panel of the electric panel
MUST be a minimum 2.5 mm².
3. The ground point of the plant must have a maximum impedance of 0.1
Ohm.
4. The ground wire must be connected to the Drive by the screw near the
symbol of the electrical ground.
5. Do not switch on the Drive without first having connected the ground
conductor to Drive and system ground point
6. If you dismantle the Drive from the electrical, the ground conductor
MUST be the last connection to be disconnected
7. 2 COMPATIBILITY' ELECTROMAGNETIC
ELECTROMAGNETIC COMPATIBILITY
. The correct setting and realization of the land circuit of a drive-motor system minimizes the emission of
EMI noise, and thus ensures a conformity to EMC regulations relating to the specific plant. Here you'll
find the solutions used to carry out the grounding as a function of Electromagnetic Compatibility (EMC).
If necessary, you can find some further information referring to the "Filtering Solutions " guide issued
by ESA Automation.
24
miniECO/miniECOplus Cap. 7: Electrical Safety
1.- In the case of a drive mounted on panel inside the electrical cabinet, it is necessary to carry out the
assembly with a good RF contact to ground. For this it is convenient to exploit large surfaces and/or
connect the metal parts to the ground using to low impedance conductors for high frequencies, for
example by using cables with a rectangular cross-section, as copper braids.
2.- Good grounding of the metal housing of the drive is not only for safety reasons, but also to EMC. If
necessary, remove layers of rust or paint or connect a good low impedance ground point (0.1 Ω) to the
electrical panel, for example copper bar.
3.- The motor casing must necessarily possess a low impedance to ground to RF (excluding the reference
drive/motor made by the cable motor), for which we cannot stick to only mechanical fastening or the one
provided by cable motor, but sometimes a good additional electrical connection should be supplied .
4.- Connect the ground terminal (screw on drive) to the metal plate on which the Drive is placed with a
connection that is as short as possible.
5.- The shield external cable must be connected to ground at both ends by using the largest possible
contact surface, using "clamp" metallic nickel plated brass or equivalent connections .
7 .3 EMERGENCY CIRCUIT
EMERGENCY
MiniECO Plus drive series have STO SIL 2 safety circuit and
therefore it is thus ensured that the motor will have no rotation,
even in the absence of a failure of the drive; current certification is
"Pending"
If you do not use the function STO follow the procedures below:
To ensure the safety of the operator and the machine itself, the
international regulations in this regard expect to remove power to the Drive
and disable it.
In relation to the "risk analysis" carried out by the manufacturer of the machine or
plant, for what concerns the Drive miniECO/miniECO Plus you can operate in two
different modes described below.
1 ° Mode Immediately cut off power supply connections and switch off signal TEN.
In this way, it is immediately free the axis of the motor. If you choose this mode
is recommended that you install an emergency brake on the motor.
2 ° Mode instantly stop the signal IEN as shown in figure "Enabling Ramp Emergency" and
aftermax 0.5 sec power connections (dependent on the type of machine and after 'risk
analysis" ).
This mode can be used for motor braking with a ramp of emergency regardless of the
signal present on pin REF and REF\.

This feature is especially designed to allow, under emergency conditions to stop the
machine, which means to stop the motor or, at least, to slow down the speed with a
dynamic suited to the mechanical systems on which it is installed.
To achieve this, the connection of the IEN signal to the +24Vdc must be severed when
the machine is put in emergency, leaving feeding to +24Vdc input TEN.
During the emergency ramp, supply +24Vdc auxiliary must also be maintained, while the
power supply can be removed at the same time as the IEN signal or after 0.5 seconds
depending on the application.
The ramp that is obtained with IEN disabled keeping TEN enabled, is set by acting on the
parameter " F3 " Emergency ramp.
The functional diagram shown in Figure 7.3.1 is mererly indicative of
the functionality of the IEN input and is not meant to replace any
other equipment devised to protect either the machinery or the
operator.

7. 4 Wiring criteria
For the correct wiring of the drive, the technical information below must be carefully followed.
In the table, the sections of the recommended conductors model and there is also the ESA Automation
code motor cable available .
Encoder Cable
The cable that connects the encoder signals must necessarily be shielded with screen connected as shown
in figure 2.6.11 . Aalternatively, you can use a shielded cable with 7 twisted pairs of wires.
Serial Cable
The cable must necessarily be an 8-way shielded model (0.22 mm² or more).
27
miniECO/miniECOplus Cap. 7: Electrical Safety
WARNING: Cables
Provide paths spaced between the power cables and those of signal.
The length of the encoder and the motor cable must not exceed the length of 50 m
for not create malfunctions due to their excessive inductance and stray capacitance;
for lengths greater than refer to the Customer Care of ESA Automation
7. 5 COMPONENTS EMC
Here below, the filter components that we recommend, depending on the different sizes of miniECO drive
are briefly reported. They allow to solve some of the EMC problems . For more information refer to our
guide " Filtering Solutions " in which the topic is treated in detail.
LINE FILTER
To meet the EMC requirements (conducted emissions) the installation must be fitted with a filter
network immediately upstream of miniECO drive, between the drive and the optional transformer.
The filter network must be sized in order to be able to correctly withstand the current drawn from the
drive.

In the case where the serial cable is located in the proximity of sources of disturbance (transmission
problems), also place a ferrite of proper id on this cable.
Here below, the steps required for a correct switch-on and switch-off of miniECO drive are described in
sequence.
SWITCH -ON
1. Supply the logic supply and +24Vdc (on the display of the drive, the writing " In " and
subsequently ’UL’ will appear one after the other
1. Switch on power (it will display ' Fr ' ).
2. Enable the Drive (signal TEN activated).
WARNING: Switch-on
When switching on the drive power supply +24Vdc, any auxiliary power
supply must always be on. Failure to comply with this procedure can cause
damage to the drive.
Where there are more than 200 ms between the logic supply and the supply of power, or in the
absence of the latter, the drive signals an alarm of too low voltage; the alarm itself is automatically
reset by restoring the correct supply.
SWITCH-OFF
1. Disable miniECO (signal TEN disabled).
2. Disconnect power supply (L1,L2,L3).
3. Disconnect power supply +24Vdc.
These three phases of sleep may also occur at the same time, but not in a different sequence from
the specified one

miniECO/miniECOplus Cap. 8: Initial Start-Up Service
The drafting of the following paragraph is made on the assumption that the operator has already included
the operation of the product in its every part. The starting procedure given here assumes that it is the
simple function of track indicative of the preliminary checks and the main operations to perform
NOTE
It is extremely useful and easy to control the installation of the drive with the
software "Drive Watcher" that in some of its features allows the set-up of the
parameters and start-up in a simple and easy way
PRELIMINARY CHECKS
a) Check that the mechanical installation follows closely the instructions in the chapter "Mechanical
Installation".
b) Check that the electrical connections comply with the ones indicated in the chapter "Electrical
Installation" and make sure of the perfect tightness of all the connectors and terminal strips.
c) Mechanically disconnect the shaft of the motor from the load (no-load motor).
DANGER
- The motor during the tests will be able to take speed and very high acceleration so it
is essential that the body of the motor is perfectly stuck in position to avoid danger to
the safety of the personnel.
- The spline MUST be kept on the drive shaft but fixed in such a way as to prevent its
release at high speeds (use the spline cover).
PROCEDURE
NOTE
In the case of the drive with the options "CANopen", "S-CAN", Networks of

5. Enable signal TEN. Check that the written " LO" appears on the display and at the same time in motor
torque.
The motor must remain under locked rotor condition, without any vibration or speed offset, otherwise
check the wiring carefully.
NOTE
In the case of Drive with set point analog continue from next point (6) up to the
point 10.
In the case of Drive in "Positioning Pulse" continue from the point 11 up to the
point 18.
6 Provide to the heads of REF\ and REF a set-point of speed of +0.5V (positive side in REF) via CN or
control board or potentiometer.
Enable the signal IEN, making sure that the display shows the writing " En " the motor must
rotate clockwise (viewed crankshaft) to 1/20 of the rated motor speed selected.
Test the operation even at maximum speed set-point to +10V.
7 To calibrate the offset change parameter " d4 ", see section "Description Parameters".
8 Turn off the miniECO drive and apply the load to the motor.
9 Repeat the steps 1 and 2, and then check the remaining calibrations of the drive miniECO
depending on the application and the actual load, as indicated in the paragraph "Description Parameters".
10 Test the machine cycle even in the worst conditions of operation and check that no alarm function I²T
intervenes (Test to be performed by connecting the drive to a PC to Drive WATCHER software).
In the case of Drive option with positioning pulse continue up to point 18.
In the case of Drive with option electrical axis ( only on family ECO is not available on
miniECO) continue up to point 25 .

miniECO/miniECOplus Cap. 8: Initial Start-Up Service
19. Set the parameters menu of IP and P as a function of the application
20. Enable the signal IEN by verifying that the display you see the writing " En ". The motor must
remain stationary.
21. Enable the signal IN0 (pin 1 terminal CN1 ), active input to +24Vdc.
22. Move the Master Encoder and check that the electrical axis repeats the movements of the Master
23. Turn off miniECO drive and apply the load to the motor.
24. Repeat the steps 1 and 2, and then check the remaining calibrations of miniECO drive depending on
the application and the actual load, as indicated in "Description Parameters". paragraph
25. Test the machine cycle even under the worst conditions of operation and check that no alarm
function I²T intervenes (for this purpose monitor OP variables on the keypad or connect the drive to a PC
with Drive Watcher software).
In the case of Drive with; with the options "CANopen", "S-CAN", "MODBUS", "S-NET"
"Electrical Axis" in network mode of field, continue up to point 28.
26. Set the parameters of the loops of space and the logs of the speed and acceleration.
27. Activate the signal TEN, enable the drive through the commands from the mains and then check
that the axis of the motor remains in torque without vibration.
28 ctivate IEN signal and start the system through by sending over the network (CANopen, S-CAN, S-
NET, MODBUS) of the appropriate commands.
NOTE
The functions related to networks of field MODBUS and S-NET require the
calibration of the axis before the use of the network itself, since the commands of the
field network and the program of analysis of the drive using the same serial port . It is
therefore extremely useful utility of AXIS Test Drive Watcher program. There are also
some more complex programs devoted to the functioning of the mechatronics features,
such as SAP for the function Stand Alone Positioner and CAM BUILDER for the
Electronic CAM. ( the latter are not available on miniECO, miniECO Plus line).
8.3 MAINTENANCE
miniECO / miniECO PLUS drive does not contain any components requirng maintenance. If you need to
replace the Drive and send it back to ESA Automation boxing should be in the same manner as the
original packaging.
If for any reason we need to intervene on nearby components to Drive pay attention, some parts
of the drive can be hot .
If you need to replace the drive you must remove the power supply and disconnect the
connectors see chapter 6.2 , even after removing the power supply DO NOT open the drive for any
reason.
32
miniECO/miniECO plus Cap. 9: Parameters
9 PARAMETERS
The Drive has several internal functions, some relatively simple other decidedly complex ones, whose
setting is implemented by PARAMETERS and REGISTERS . The simpler functions will rely
exclusively on parameters while the more complex ones also require the setting of specific REGISTERS
. The local keypad serves to carry out the setting only on the parameters: the display of the alarms for
complex applications or for the use of field networks and the mechatronics functions that make extensive
use of the registers in addition to parameters are essential to the use of the " Drive Watcher " program.
The Drive has two keys in front of a keyboard + ENTER
) and a two-digit display It is necessary to
install the "Drive Watcher" program on your PC, for a comprehensive programming of all the
features, but you can still enter the parameters of the standard functions by the local keyboard. The
display shows the status of operation, the alarms and the parameters with their values.
Views at POWER ON
When you turn on the Drive, it displays the status of operation. The initialization of the internal software
is recognizable from the view " In " ( Initialisation, that appears for a few seconds); then the message "
Fr " (Free ) indicates that the drive is powered up and ready to receive commands or " UL " (Under
Level ) if there is no power supply.
By activating TEN signal, the motor is supplied, the performed function depends on the IEN signal. If
IEN is also active, the display shows "En" ( Enable ), the drive provides torque to the motor and is
enabled to follow the analog signal (if the parameter c9 = 0 ) present on pin REF and REF/" If IEN is
disabled the display shows "Lo" ( Lock ) and the drive provides torque to the motor, but remains in
position.

SPECIAL MENU
The menus listed below differ in some details from general rules described above
With " SE "menu you can check the alignment of the resolver or Encoder: the value represents the phase shift in
electrical degrees of the resolver or Encoder with relation to the electric field of the magnets. Thus, if the phase shift
is important disconnect mechanically the Resolver or Encoder and rearrange the mechanical position with relation to
the motor shaft and can carry out the alignment. The two procedures are slightly different for the Resolver or the
Encoder: please carefully follow the instructions shown in Figure 7.1.9 .
"SE" menu appears only when the parameter c9 = 0 .
To enter this menu you must press the [ENTER] key when “SE” is on the display and present.

miniECO/miniECOplus miniECOplus Series
Place of installation
Since the regulator is part of IP20 protection degree, the installation location should be chosen in such a
way that even the surrounding environment ensures safe operation of the Drive. The place of installation
must conform at least to IP54 protection degree.
WIRING
If the harness of STO is located on the outside of the place of installation, the cables should be routed in a
lasting way (fixed), protected from external damage (e.g., with a raceway), inserted in different sheaths or
protected one by one by connecting to the ground. If the wiring is inside the established place, installation
must be carried out in compliance with the terms indicated in EN 60204-1.

External DC BUS
DC BUS terminal M5 allows to wire up a system allowing the use of the energy regenerated from
electronic braking motors and use it ( if the cycle allows ) for other drives, thus limiting the amount of
heat dissipation on braking resistors. This use allows to connect several drives together ( max 4) as if a
modular system is used, the drives must be of similar powers
.
Alternatively, a component called ESA Automation RIG 400 can also be used
which allows a total re-use of drive energy regenerated making it also available
for the auxiliary services on machine
Normally the motors which are mounted on the vertical axis are equipped with a parking brake.
The management of the parking brake is actually seemingly simple, but, under particular
conditions, it hides some traps.
For example, during emergency braking with consequent disconnection
of the power voltage from the drive, it is necessary to carry out
controlled braking and finally attach the parking brake with the motor
still in torque performing a sequence of timings suitable to prevent the
axis from dropping from the position in which it was brought at the end
of controlled braking. This mechanism is implemented within the drive
and is selectable by a parameter. The information for its management is
to be found in the manual "Additional Information"
