14 Test Operation, Adjustment, Maintenance and Troubleshooting
14.6 Judgment by Error Codes and Representation of Error Codes
Error codes in shaded columns are added in FX
Check the cable connection between the
programming panel (PP) / programming device and
the PLC. This error may occur when a cable is
disconnected and reconnected during PLC
monitoring.
• Inverter communication, computer link and
programming:
Ensure that the communication parameters are
correctly set according to their applications.
• N:N network, parallel link, etc.:
Check programs according to applications.
• Remote maintenance:
Ensure modem power is ON and check the
settings of the AT commands.
• Wiring:
Check the communication cables for correct
wiring.
STOP the PLC, and correctly set the parameters.
During programming, each instruction is checked. If
a syntax error is detected, modify the instruction
correctly.
