PG slip error
Action and Reset
Pr.04-75 Encoder Slip Range (Default: 50% of Maximum Output Frequency (Pr.03-
50))
Pr.04-76 Encoder Slip Detection Time (Default: 0.05 second)
Pr.04-72 (Default: 2)
0: Warn and keep operation
1: Fault and ramp to stop
2: Fault and stop operation
PGF4 is a warning when Pr.04-72=0. It will be automatically cleared when
Auto the difference between Frequency command and feedback frequency is
smaller than encoder slip range.
Manual PGF4 is a fault when Pr.04-72= 1 or 2. You must reset it manually.
Resets immediately
If PGF4 is a warning, it will not be recorded.
If PGF4 is a fault, it will be recorded.
Verify motor specification and set motor parameter settings again (Pr.00-10–Pr.00-16)
Set encoder-related parameters again (Pr.00-20–Pr.00-23), and check if the wiring is
correct.
Adjust acceleration /deceleration time (Pr.00-71–Pr.00-78)
Properly increase Pr.04-75 and Pr.04-76 settings

Fault Name
KPED-LE02
External fault
Action and Reset
MI#10 = EF and the MI terminal is ON
Immediately act
Pr.02-16 (Emergency Stop (EF) & Forced Stop) (Default: 0)
0: Coast to stop
1: According to deceleration Time 1
2: According to deceleration Time 2
3: According to deceleration Time 3
4: According to deceleration Time 4
5: According to Pr.00-82
Manual reset
Resets only after the external fault is cleared (terminal status is recovered)
Yes
Press RESET key after the fault is cleared.
In PG mode, when motor the difference
between output frequency command and
motor feedback frequency is larger than
encoder slip range (Pr.04-75) and starts to
count the time, and the time error occurred
exceeds Pr.04-76 (Encoder Slip Detection
Time), PGF4 occurs.
Corrective Actions
When external fault terminal is OFF, drive
stops output.
