Fault Name
Under PG mode, when the motor frequency exceeds
the encoder observer stall level (Pr. 10-10) and starts to
PG feedback stall
count, the fault time is longer than the detection time of
(GF3)
encoder observer stall (Pr. 10-11), then PGF3 fault
occurs.

Reset encoder parameter (Pr. 10-01)
Set proper value for Pr. 01-00.
Reset ASR parameters.
Set correct accel./decel. time.
Reset proper values for Pr. 10-10 and Pr. 10-11
Fault Name
Under PG mode, when the motor frequency exceeds
PG slip error encoder observer slip range (Pr. 10-13) and starts to
(PGF4) count, the fault time is longer than the detection time of
encoder observer slip (Pr. 10-14), PGF4 fault occurs.
Action and Reset

0: warn and keep operation
1: warn and ramp to stop
2: warn and coast to stop
When Pr. 10-15=0, PGF4 is a "Warning", when the deviation between
Auto output frequency and motor frequency is smaller than the encoder
observer slip range, the warning is automatically cleared.
Manual When Pr. 10-15=1 or 2, PGF4 is a "Fault". You must reset manually.
Immediately reset
When Pr. 10-15=1 or 2, PGF4 is a "Fault", and the fault is recorded.
Reset correct values for Pr. 10-13 and Pr. 10-14.
Reset ASR parameters.
Set correct accel./decel time.
Reset encoder parameters (Pr. 10-01).
Reset proper accel./decel. time.
Reset proper setting values for Pr. 06-12 and Pr. 11-17–Pr. 17-20.
Remove causes of motor shaft lock.
Check the action sequence of the system.
