Fault Name
KPED-LE02
Phase loss
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
Use Pr.04-02 to set to reset automatically or manually
Resets immediately when DC bus voltage is higher than Pr.07-51 (Brake Transistor
Level)
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.
Tighten the terminal screws with the torque listed in the user manual.
Make sure the wiring is correct.
Replace the broken part of the cable.
Check the status of three-phase power.
Adjust Pr.07-51 (Brake Transistor Level) setting value.

IGBT overheating fault
Action and Reset
When IGBT temperature is higher than oH1 Fault Level shown in the table below
When IGBT temperature is higher than the protection level for more than 100 ms
Manual reset
Resets manually when temperature is lower than [IGBT limits – 5°C]
Yes
1. Check the ambient temperature.
2. Regularly inspect the ventilation hole of the control cabinet.
3. Change the installed place if there are heating objects, such as brake
resistors, in the surroundings.
4. Install/add cooling fan or air conditioner to lower the temperature inside the
cabinet.
Remove the obstruction or replace the cooling fan.
Increase ventilation space of the drive.

Input phase loss warning
Corrective Actions
If IGBT temperature is higher than oH1 Fault
Level shown in the table below when drive
detects overheating of IGBT, keypad displays
oH1 fault, not oH1 warning.
