10. Troubleshooting
Operating Panel Display
Cause
The EEPROM chip is damaged.
Operating Panel Display
Cause
Motor is short circuited to the ground.
Operating Panel Display
Cause
Accumulative running time reaches the
setting value.
Operating Panel Display
Cause
User-defined fault 1 is input via DI.
User-defined fault 1 is input via virtual I/O.
Operating Panel Display
Cause
User-defined fault 2 is input via DI.
User-defined fault 2 is input via virtual I/O.
Operating Panel Display
Cause
Accumulative power-on time reaches the
setting value.
Operating Panel Display
Cause
The output current of AC drive is smaller
than F9-64 (load loss detection level).
11
Operating Panel Display
Cause
PID feedback is smaller than the setting
value of FA-26 (detection level of PID
- 300 -
feedback loss).
Fault Name
EEPROM read-write fault
Possible Solution
Replace the main control board.
Fault Name
Short circuit to ground
Possible Solution
Replace cable or motor.
Fault Name
Accumulative running time reached
Possible Solution
Clear the record through parameter initialization.
Fault Name
User-defined fault 1
Possible Solution
Reset the operation.
Reset the operation.
Fault Name
User-defined fault 2
Possible Solution
Reset the operation.
Reset the operation.
Fault Name
Accumulative power-on time reached
Possible Solution
Clear the record through parameter initialization.
Fault Name
Load loss
Possible Solution
Check whether load is disconnected or the setting of F9-64
and F9-65 (load lost detection time) satisfies actual running
condition.
Fault Name
PID feedback lost during running
Possible Solution
Check PID feedback or set FA-26 properly.
