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.

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

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.

Reset method
Auto
When Pr.10-15=0, PGF4 is a “Warning”. When the deviation between the 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.
