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

PG slip error
(PGF4)
Under PG mode, when the motor frequency exceeds
encoder observer slip range (Pr.10-13) and starts to
count, the fault time is longer than the detection time of
encoder observer slip (Pr.10-14), PGF4 fault occurs.
Action and Reset
Action level Pr.10-13
Action time Pr.10-14
Fault treatment parameter
Pr.10-15
0: Warn and keep operation
1: Fault and ramp to stop
2: Fault and coast to stop
Reset method
Auto
When Pr.10-15=0, PGF4 is a “Warning”, when the deviation between
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.
Reset condition Immediately reset
Record When Pr.10-15=1 or 2, PGF4 is a “Fault”, and the fault is recorded.
Cause Corrective Actions
Incorrect settings for PG feedback
parameters
Reset correct values for Pr.10-13 and Pr.10-14.
Incorrect settings for ASR
parameters and accel./decel. time
Reset ASR parameters.
Set correct accel./decel time.
Incorrect settings of encoder
parameters
Reset encoder parameters (Pr.10-01).
Accel./Decel. time is too short Reset proper accel./decel. time.
Incorrect settings of torque limit
parameters (Pr.06-12,
Pr.11-17–20)
Reset proper setting values for Pr.06-12 and Pr.11-17–Pr. 17-20.
Motor shaft lock Remove causes of motor shaft lock.
Mechanical brake is not released Check the action sequence of the system.
