Probable causes
Overshooting/undershooting are
occurring.
The reference speed is too high.
The settings in F1-08 and F1-09 aren't
appropriate.
There is a break in the PG wiring.
The PG is wired incorrectly.
Power isn't being supplied to the PG.
The load is too large.
The acceleration time and decelera-
tion time are too short.
The load is locked.
The settings in F1-10 and F1-11 aren't
appropriate.
Protective and Diagnostic Functions
Corrective Actions
• Make sure that the settings in L6-02
and L6-03 are appropriate.
-
• Check the mechanical system and
correct the cause of the overtorque.
• Make sure that the current setting in
L6-05 and time setting in L6-06 are
- appropriate.
• Check the mechanical system and
correct the cause of the overtorque.
• Make sure that the settings in L6-02
and L6-03 are appropriate.
-
• Check the mechanical system and
correct the cause of the overtorque.
• Make sure that the current setting in
L6-05 and time setting in L6-06 are
- appropriate.
• Check the mechanical system and
correct the cause of the overtorque.
Adjust the gain again.
Check the reference circuit and refer-
ence gain.
Check the settings in F1-08 and F1-09.
Fix the broken/disconnected wiring.
Fix the wiring.
Supply power to the PG properly.
Reduce the load.
Lengthen the acceleration time and
deceleration time.
Check the mechanical system.
Check the settings in F1-10 and F1-11.
- Remove the cause of the external fault.
