■ Checking LED Operation
Table 15 LED Display
Note: If communication stops while the drive is running, check the following:
• Is the CC-Link properly installed?
• Is the CC-Link communication line connected to the CC-Link Option correctly? Is it loose?
• Is the PLC program working? Has the PLC CPU stopped?
• Did a momentary loss in power interrupt communications?
Operator Display Fault Name
oFb02
CC-Link Option Fault (CN5-B)
Two of the same option cards are connected at the same time.
Cause Possible Solution
Option cards AI-A3 or D1-A3 were connected to the CN5-
B port while an option card was already connected to CN5-
A.
⇒ Only one type of option input card AI-A3 or DI-A3 can be connected to the drive. Only this option card for CANopen can be
connected to CN5-A.
Operator Display Fault Name
oFc00
CC-Link Option Fault (CN5-C)
Non-compatible option card is connected.
Cause Possible Solution
Non-compatible option connected to the drive. ⇒ Connect the correct option card to CN5-A.

Check for wiring errors.
⇒ Correct the wiring.
⇒ Remove and ground shorts and reconnect loose wires.
YES
Programming error on the master side ⇒ Check communications at start-up and correct programming errors.
Communication circuitry is damaged.
Perform a self-diagnostics check.
⇒ Replace the drive if the fault continues to occur.
L.RUN Switches on when data is being received normally. Turns off when the receive data is interrupted.
SD Lights whenever the drive is sending data.
RD Lights whenever the drive is receiving data.
L.ERR Lights when a CRC or abort error occurs.
