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.
Action and Reset
Action level Pr. 10-10
Action time Pr. 10-11

0: warn and keep operation
1: warn and ramp to stop

Reset method Manual reset
Reset condition Immediately reset
Record Yes
Cause Corrective Actions
Incorrect setting of encoder
parameter
Reset encoder parameter (Pr. 10-01)
Pr. 01-00 is set too small Set proper value for Pr. 01-00.
Incorrect setting for ASR
parameters and accel./decel. time
Reset ASR parameters.
Set correct accel./decel. time.
Incorrect setting for PG feedback
stall
Reset proper values for Pr. 10-10 and Pr. 10-11

45
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: warn and ramp to stop
2: warn 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.
