Fault Name Fault Descriptions Corrective Actions
LvS
Lv at stop
Fault
DC BUS voltage is less than
Pr.03-00 at stop 1. Check if the input voltage is normal
2. Check for possible sudden load
oH1
IGBT over heat
Fault
IGBT overheating
IGBT temperature exceeds
protection level
1~50HP: 105
; 60~100HP:
℃
110
℃
1. Ensure that the ambient temperature
falls within the specified temperature
range.
2. Make sure that the ventilation holes are
not obstructed.
3. Remove any foreign objects from the
heatsinks and check for possible dirty
heat sink fins.
4. Check the fan and clean it.
5. Provide enough spacing for adequate
ventilation.
oH2
Heat Sink oH
Fault
Heatsink overheating
Capacitance temperature exceeds
protection level.
1~50HP: 80
; 60~100HP: 65
℃ ℃
1. Ensure that the ambient temperature
falls within the specified temperature
range.
2. Make sure heat sink is not obstructed.
Check if the fan is operating
3. Check if there is enough ventilation
clearance for AC motor drive.

oL
Over load
Fault
Overload
The AC motor drive detects
excessive drive output current.
1. Increase AFE2000 output capacity.
Replace with the next higher power
AFE2000 unit.

1. Press “RESET” key to the factory setting
2. Return to the factory.
cF2
EEPROM read err
Fault
Internal EEPROM can not be
read. 1. Press “RESET” key to the factory setting
2. Return to the factory.
