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

Action and Reset
1: Software detection: DC bus is lower than Pr.07-51 (Brake Transistor Level) and DC
bus ripple is higher than 30V
2: Software detection: Power factor angle is smaller than 80 degree and DC bus ripple
is higher than 30V
3: Hardware automatically detects external phase loss
Hardware automatically detects external phase loss
Pr.04-31 (Phase Loss Protection during Operation)
This warning will be automatically cleared after drive stops.
Resets once the drive stops
Pr.04-31 Phase Loss Protection during Operation (Default: 2)
When Pr.04-31=0, PHL is a warning and will not be recorded.
When Pr.04-31=1 or 2, PHL is a fault and will be recorded.
Verify wiring of the main circuit.
Use the model with voltage that matches the power.
If the power of main circuit works well, check if the MC of the main circuit is broken.
Cycle the power after verifying the power is normal. If PHL still occurs, return to the
factory for repair.
Chapter 9 Warning and Fault CodesEB3000
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.
