0: Warn and continue operation
1: Fault and ramp to stop
2: Fault and coast to stop
When Pr.10-15 = 0, PGF4 is a "Warning". When the deviation
Auto 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.
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.11-20.
Remove causes of motor shaft lock.
Check the action timing of the system.

Fault Descriptions
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.
