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 Condition
Pr.10-13
Action Time
Pr.10-14
Fault Treatment Parameter
Pr.10-15
0: Warn and continue 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 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.
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.11-20.
Motor shaft lock
Remove causes of motor shaft lock.
Mechanical brake is not released
Check the action timing of the system.
