[DESIGN PRECAUTIONS]
WARNING
● Make sure to set up the following safety circuits outside the tension controller to ensure safe system
operation even during external power supply problems or tension controller failure. Otherwise,
malfunctions may cause serious accidents.
- Note that when an error occurs in a relay or transistor of an output circuit, the output might stay on
or off. For output signals that may lead to serious accidents, external circuits and mechanisms
should be designed to ensure safe machinery operation in such a case.
● Most importantly, set up the following: an emergency stop circuit, a protection circuit, an interlock
circuit for opposite movements (such as normal vs. reverse rotation), and an interlock circuit (to
prevent damage to the equipment at the upper and lower torque limits and upper and lower tension
limits).
● In an output circuit, when a load current exceeding the current rating or an overcurrent caused by a
load short-circuit flows for a long time, it may cause smoke and fire. To prevent this, configure an
external safety circuit, such as a fuse.
● For the operating status of each station after a communication failure of the network, refer to relevant
manuals for the network. Incorrect output or malfunction may result in an accident.
[DESIGN PRECAUTIONS]
CAUTION
● If a power failure or an abnormal voltage drop occurs, the tension controller stops, and output is
turned off.

● Make sure to cut off all phases of the power supply externally before attempting installation or wiring
work. Failure to do so may cause electric shock or damage to the product.
● Use the product within the generic environment specifications described in LE7-40GU APPLICATION
MANUAL (SH-081822ENG). Never use the product in areas with excessive dust, oily smoke,
conductive dusts, corrosive gas (salt air, Cl2, H2S, SO2 or NO2), flammable gas, vibration or impacts,
or expose it to high temperature, condensation, or rain and wind. If the product is used in such
conditions, electric shock, fire, malfunctions, deterioration or damage may occur.
[INSTALLATION PRECAUTIONS]
CAUTION
● Do not touch the conductive parts of the product directly. Doing so may cause device failures or
malfunctions.
● Always wear an anti-static wristband and discharge static electricity from the body before handling the
extension option. Failure to do so may cause the extension option to fail or malfunction.
● When drilling screw holes or wiring, make sure that cutting and wiring debris do not enter the
ventilation slits of the tension controller. Failure to do so may cause fire, equipment failures or
malfunctions.
● Install the product on a flat surface. If the mounting surface is rough, undue force will be applied to the
PC board, thereby causing nonconformities.
● Install the product securely using mounting screws or fixtures.
● Connect the extension options securely to their designated connectors. Loose connections may
cause malfunctions.
● Make sure to affix the extension option with tapping screws. Tightening torque should follow the
specifications in the manual. If the screws are tightened outside of the specified torque range, poor
connections may cause malfunctions.
● Work carefully when using a screwdriver such as installation of the product. Failure to do so may
cause damage to the product or accidents.
● Connect the input/output cables and power cable securely to their designated connectors. Loose
connections may cause malfunctions.
● Turn off the power to the tension controller before attaching or detaching the optional devices. Failure
to do so may cause equipment failures or malfunctions.

[WIRING PRECAUTIONS]
WARNING
● Make sure to cut off all phases of the power supply externally before attempting installation or wiring
work. Failure to do so may cause electric shock or damage to the product.
● Make sure to properly wire to the terminal block (Spring clamp type) in accordance with the following
precautions. Failure to do so may cause electric shock, equipment failures, a short-circuit, wire
breakage, malfunctions, or damage to the product.
- The disposal size of the cable end should follow the dimensions described in the manual.
- Twist the ends of stranded wires and make sure that there are no loose wires.
- Do not solder-plate the electric wire ends.
- Do not connect more than the specified number of wires or electric wires of unspecified size.
- Affix the electric wires so that neither the terminal block nor the connected parts are directly
stressed.
[WIRING PRECAUTIONS]
CAUTION
● Perform class D grounding (grounding resistance: 100  or less) of the grounding terminal on the
tension controller with a wire 0.2 to 1.5 mm2. Do not use common grounding with heavy electrical
systems.
● Connect the power supply wiring to the dedicated terminals described in this manual. If an AC power
supply is connected to a DC input/output terminal or DC power supply terminal, the tension controller
will burn out.
● Do not wire vacant terminals externally. Doing so may damage the product.
● Install module so that excessive force will not be applied to terminal blocks, power wire, or
communication cables. Failure to do so may result in wire damage/breakage or tension controller
failure.
● Make sure to observe the following precautions in order to prevent any damage to the machinery or
accidents due to malfunction of the tension controller due to the effects of noise.
- Do not bundle the power line and communication cables together with or lay them close to the
main circuit, high-voltage line, load line or power line. As a guideline, lay the power line, control
line and communication cables at least 100 mm away from the main circuit, high-voltage line, load
line or power line.
- Ground the shield of the shielded wire or shielded cable at one point on the tension controller.
However, do not use common grounding with heavy electrical systems.
- Ground the shield of the analog input/output cable at one point on the signal receiving side.
However, do not use common grounding with heavy electrical systems.

COMMUNICATION
Since LE7-40GU supports the slave function of CC-Link IE Field Network Basic communication which is an open FA network,
it can communicate with various CC-Link IE field network Basic master stations.
Precautions
3
• Since CC-Link IE Field Network Basic uses port No. [61451] as a device detection port, when port No. [61451] is used for
another communication function, CC-Link IE Field Network Basic connection cannot be used.
• Since LE7-40GU handles a number of object functions besides the CC-Link IE Field Network Basic connection function,
the response performance with respect to access from the master station may deteriorate. In such a case, it is necessary to
adjust the link scan time or the timeout time on the master station side. The recommended setting value is 50 ms or more.

Continuous setting/continuous monitoring
Data specified in advance can be set and monitored continuously by setting the continuous setting execution (RY2E) and
continuous monitor execution (RY2E) in the master station to ON.
For continuous setting data, the data set for RAM writing is not stored during a power failure.
The latest data existing in LE7-40GU when the master station gives the send request can be monitored continuously.
However, regarding the update of parameters for which the monitor update cycle is specified by the setting in LE7-40GU, the
data is updated in the specified update cycle if the specified update cycle is longer than the monitor update cycle in the send
request given by the master station.

Access by request command

For any access to data in LE7-40GU from the master station, data can be read and written by handshake between the
"request command execution (RY2F)" flag and the "request command completion (RX2F)" flag.
This access is performed using a 2-word word device of the master station.
This 2-word data is comprised of the request command, to which the upper 4 bits of the first word are assigned, and the
request code, to which the lower 2 bits are assigned, and the setting data, to which the next word is assigned.
bit 15 to 12 bit 11 to 0
Request command Request code
Setting data
There are three types of request command, Data Monitor, Writing to RAM, and Writing to RAM + ROM, according to the
selection of data reading and writing method.

not stored in the case of a power failure. not stored in the case of a power failure.
In the ROM for storage against power interruption, the allowable number of times of writing is limited. Accordingly, data
cyclically written and updated by the PLC must be written only to the RAM.
Request command Contents of execution Execution result
H0 Monitor Monitored value
H1 Writing to RAM Writing result
H2 Writing to RAM + ROM Writing result
The request code is the data number (address) of the data that executes the request command. The subsequent data setting
is the data to be written to the data number, and if the request command is the monitor, the data setting data is ignored.
When double word data is written to send data in the master station, and the handshake is executed by turning ON/OFF the
request command execution flag and request command completion flag as follows, LE-70GU sends back the request
command execution request.
1. The master station is set to request command execution ON.

2. LE7-40GU executes processing when receiving turning ON of the request command execution by the master station.
3. LE7-40GU turns ON the request command completion.
4. The master station receives the request command completion ON.
5. The master station is set to request command execution OFF.

6. LE7-40GU receives turning OFF of the request command execution by the master station.
7. LE7-40GU turns OFF the request command completion.
8. The master station receives the request command completion OFF.

Please perform reading of the execution results of the request command between step 4 and 5 of the handshake procedure.
If an error occurs, in the execution result with respect to the request command from the master station, turn on the network
alarm occurrence flag and output the device number where the alarm occurred to the network alarm device number monitor.
For the request command execution result, refer to the following.
Request code
The numerical value of each parameter corresponding to the request code is treated as real number data without a decimal
point.
In addition, the minimum and maximum values are determined for LE7-40GU, and when a value exceeding this data is
written, it is automatically rewritten to the minimum or maximum value.
In this case, an "Out of data range" alarm is generated.

4 SLMP COMMUNICATION
Since the LE7-40GU supports the SLMP communication function which is an open FA network, it can communicate with
various SLMP-compatible devices. Also, up to seven LE7-40GU units can be connected to one SLMP-compatible device to
carry out data monitoring and parameter writing.
Precautions
If you replace an external device or an SLMP equipment due to a malfunction, the MAC address of the connected device
changes, so communication may not be possible. (When exchanged with the same IP address equipment)
If you replace a device in the Ethernet, restart all the devices in the network.

of the LE7-40GU screen.
5. If you want to change the SLMP station No. (default: 2), change it on the "SLMP station number" screen on the LE7-
40GU screen.
Precautions
For SLMP communication, only the LE7-40GU station No. and IP address can be changed on the LE7-40GU screen.
To change the port number or SLMP equipment communication settings, they must be set with GT Designer3 (GOT2000).
1. Obtain the "Screen package data for SLMP communication" from your local Mitsubishi Electric representative.

Station Number command

Determine the station No. of the LE7-40GU to be accessed by the station No. command of the SLMP equipment D device (D
106).
By setting the station No. command to 0, simultaneous settings can be done for all LE7-40GU units.
Station No. command Function
1 to 7 Individual access to designated LE7-40GU
0 Simultaneous access to all LE7-40GU units

By simply turning on continuous settings execution (D103, b13) and continuous monitor execution (D103, b14) of SLMP
equipment, preset data can be set and monitored continuously.
For any access to data in LE7-40GU from the SLMP equipment, data can be read and written by handshake between the
"request command execution" flag and the "request command completion" flag.
Double word data from the SLMP equipment is used for this access.
Setting data
Writing data is reflected in the settings based on a Writing data is reflected in the settings based on a Execute data writing to the RAM + ROM (for
data read request from the SLMP equipment but is data write request from the SLMP equipment but is storage against power interruption).
not stored against power interruption. not stored against power interruption.
Since there is a limit on the number of writable times in the ROM for power failure storage, it is necessary to write the data
where write updates are performed periodically from the PLC only to RAM.
The request code indicates the data No. (address) of data for which the request command is executed. Also, the subsequent
data setting is the data to be written to that data number.
If the request command is a monitor, the data setting data is ignored.
When double word data is written to send data in the SLMP equipment, and the handshake is executed by turning ON/OFF
the request command execution flag and request command completion flag as follows, LE7-40GU sends back the request
command execution result.
If an error occurs, triggered by the request command from the SLMP equipment, the local station turns ON the network alarm
occurrence flag and outputs the device No. that has the error to the monitor of the device number of the network alarm.
1. SLMP compatible device executes request command (D103, b15) ON.

2. The LE7-40GU processes in accordance with the SLMP equipment request command execution ON.
4. The SLMP equipment receives request command completion (Dn+3, b15) ON.
5. The SLMP equipment sets request command completion OFF.
6. The LE7-40GU receives request command execution OFF from the SLMP equipment.
8. The SLMP equipment receives turning OFF of the request command completion.

Connection to LE7-40GU should be performed as the following procedure.
■Wire size
No. of wire per terminal Wire size
Single wire/Strandwire Ferrules with insulation sleeve Ferrules withoutinsulation sleeve
One wire AWG24 to 16 AWG23 to 16 AWG23 to 16
■Treatment of wire ends

Strip the cable about 10 mm from the tip to connect a wire ferrule at the striped area. Failure to do so may result in electric
shock or short circuit between adjacent terminals because of the conductive part. If the wire strip length is too short, it may
result in the poor contact to the spring clamp terminal part.
When using a wire ferrule with an insulating sleeve, choose a wire with proper cable sheath referring to the above outside
dimensions, otherwise the wire cannot be inserted easily.
- Strand wire/single wire - Ferrule with insulation sleeve
Insulation sleeve Contact area
(Crimp area)
10 mm 10 mm
2 to 2.8 mm 14.5 to 16 mm
The following table shows wire ferrules and tools for wire ferrules compatible with the terminal block. Use of items other than
these may result in not being able to remove the wire ferrule, so carefully check that the wire ferrule can be unplugged.

■Connection and disconnection of the cable

Spring clamp terminal block is push-in type, therefore, wiring without a tool is possible by simply inserting the connecting
terminal to the terminal block. However, the stranded wire does not comply with the push-in type, and a tool is required for
connecting cables.
• Connection of the cable
Fully insert a cable or bar solderless terminal whose end has been properly processed into the wire insertion opening.
If the cable or bar solderless terminal cannot be inserted with this procedure, fully insert the cable or bar solderless terminal
while pushing the open/close button with a flathead screwdriver having a tip width of 2.0 to 2.5 mm. After fully inserting the
cable, remove the screwdriver.
Do not tighten terminal screws exceeding the specified torque range. Otherwise it may cause equipment failure or
malfunction.
When wiring with the thick electric wire, make sure to prevent the conductive parts from protruding to the front of the terminal
block.

One wire AWG24 to 16 AWG23 to 16 AWG23 to 16
■Treatment of wire ends

Strip the cable about 10 mm from the tip to connect a wire ferrule at the striped area. Failure to do so may result in electric
shock or short circuit between adjacent terminals because of the conductive part. If the wire strip length is too short, it may
result in the poor contact to the spring clamp terminal part.
When using a wire ferrule with an insulating sleeve, choose a wire with proper cable sheath referring to the above outside 7
dimensions, otherwise the wire cannot be inserted easily.

7.2 Wiring 113
■Connection and disconnection of the cable
Spring clamp terminal block is push-in type, therefore, wiring without a tool is possible by simply inserting the connecting
terminal to the terminal block. However, the stranded wire does not comply with the push-in type, and a tool is required for
connecting cables.
• Connection of the cable
Fully insert a cable or bar solderless terminal whose end has been properly processed into the wire insertion opening.
If the cable or bar solderless terminal cannot be inserted with this procedure, fully insert the cable or bar solderless terminal
while pushing the open/close button with a flathead screwdriver having a tip width of 2.0 to 2.5 mm. After fully inserting the
cable, remove the screwdriver.
Do not tighten terminal screws exceeding the specified torque range. Otherwise it may cause equipment failure or
malfunction.
When wiring with the thick electric wire, make sure to prevent the conductive parts from protruding to the front of the terminal
block.

Used coil/holding register

The coil and holding register used for MODBUS communication of LE7-40GU are as follows.
The coil is an area to store bit data and the holding register is an area to store word data. Each slave station has coils from
H0000 to H02F and H1000 to H102F as well as holding registers from H0000 to H015F and H1000 to H115F.
The usage of each kind of address is as follows.
• Coil (for Master stationSlave station)
An area in which the master station writes an instruction to the slave station
• Coil (for Slave stationMaster station)
An area in which the slave station writes the execution result of the instruction from the master station.
By reading the area of this coil from the master station, it becomes possible to monitor the instruction execution result of the
slave station by the master station.

• Holding register (for master station monitoring)
The status of the slave station monitored by the master station is stored in this area.
Slave station monitoring is performed by the master station by reading the area of the holding register by the master station.
• Holding register (for slave station RAM write)

Data exchange between the master station and the slave station
The master station reads and writes data from/to the coil and holding registers of the slave station, enabling monitoring of the
slave station and setting of parameters.
Coil (bit data)

■Coil for Master stationSlave station
An area used to write instructions to the slave station.
■Coil for Slave stationMaster station

The execution result of the instruction is an area for writing.
Holding register (word data)

■For monitoring by the master station
The status of the slave station monitored by the master station is stored in this area.
■For writing to RAM in the slave station

Data to be written to the RAM in the slave station is stored in this area.
RAM writing data is reflected in the settings, but is not stored in the case of power failure.
It can be written only to LE7-40GU.
■For writing to RAM + ROM in the slave station

An area to store data to perform the above RAM writing + data power failure writing. 7
• The numerical value of each parameter is treated as real data without a decimal point. The data defines the
minimum value and the maximum value within LE7-40GU and automatically rewrites it to the minimum
value or the maximum value when writing data outside the range. At that time, a network alarm "22" is
output to the alarm display (H00EB) of the holding register.
• For holding registers where change of password of monitor, parameter list of setting items="", if the
password setting and the password input do not match, the holding register cannot be written to, the monitor
value of the holding register is rewritten with a numerical value of maximum value +1, and the set numerical
value can no longer be monitored.
• If an error occurs triggered by the request from the master station, the slave station turns ON the coil of the
network alarm occurrence flag (H101A), and outputs the address of the holding register that has the error to
the holding register of the device number of the network alarm (H00EC).
