Causes
A data error occurred due to electric interference
Option is damaged
Connection Time-out
The option received an external fault from the
controller.
A programming error occurred on the controller
side.
The option connected to connector CN5-A is not
compatible.
The option connected to option port CN5-A was
changed during run.
A fault occurred in the option.
A fault occurred in the option.
The option connected to connector CN5-B is not
compatible.
An option of the same type is already installed in
option port CN5-A, CN5-B, or CN5-C.
The option connected to connector CN5-C is not
compatible.
An option of the same type is already installed in
option port CN5-A, CN5-B, or CN5-C.
Causes
The node address for the communication option is
not in the permitted setting range.
The communications cable wiring is incorrect.
There is a short circuit in the communications cable
or the communications cable is not connected.
A programming error occurred on the controller
side.
There is damage to the communications circuitry.
The termination resistor setting for MEMOBUS/
Modbus communications is incorrect.
Comm. Option Parameter Not Upgraded
Possible Solutions
• Prevent noise in the control circuit, main circuit, and ground
wiring.
• If you identify a magnetic contactor as a source of noise,
install a surge absorber to the contactor coil.
• Use only recommended cables or other shielded line. Ground
the shield on the controller side or the drive input power side.
• Separate all communication wiring from drive power lines.
Install an EMC noise filter to the drive power supply input.
• Counteract noise in the master controller (PLC).
If there are no problems with the wiring and the error continues to
occur, replace the option.
• The option Requested Packet Interval (RPI) timer timed out
• Make sure that RPI time is set properly
1.
Find the device that caused the external fault and remove the
caus.
2.
Clear the external fault input from the controller.
Examine the operation of the controller program.
Connect the option to the correct connector.
• Use connector CN5-A when you connect the option.
To use other options, refer to those option manuals.
1.
De-energize the drive.
2.
Connect the option to the correct option port.
1.
De-energize the drive.
2.
Make sure that the option is correctly connected to the
connector.
3.
If the problem continues, replace the option.

Connect the option to the correct option port.
Possible Solutions
Set F6-10 [CC-Link Node Address] correctly.
Correct wiring errors.
• Repair the short-circuited or disconnected portion of the cable.
• Replace the defective communications cable.
Examine communications at start-up and correct programming
errors.
• Do a self-diagnostics check.
• If the problem continues, replace the control board or the
drive. Contact Yaskawa or your nearest sales representative to
replace the control board.
On the last drive in a MEMOBUS/Modbus network, set DIP
switch S2 to the ON position to enable the termination resistor.
Re-energize the drive to update the communication option
parameters.
