DC BUS voltage is less than Pr.06-00 during constant speed.
Corrective Actions:
Lvn
1. Check if the input voltage is normal
2. Check for possible sudden load
Low voltage at stop
Corrective Actions:
LvS
1. Check if the input voltage is normal
2. Check for possible sudden load
Phase Loss
Corrective Actions:
orP
Check Power Source Input if all 3 input phases are connected without
loose contacts.
IGBT overheating
IGBT temperature exceeds protection level
40 to100HP: 100
oH1
Corrective Actions:
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.
Heatsink overheating
Capacitance temperature exceeds cause heatsink overheating.
oH2
Corrective Actions:
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.
Motor overheating
The AC motor drive detecting internal temperature exceeds the setting of
Pr.06-30 (PTC level)
oH3
Corrective Actions:
1. Make sure that the motor is not obstructed.
2. Ensure that the ambient temperature falls within the specified
temperature range.
3. Take the next higher power AC motor drive model.
Motor 1 overload
Corrective Actions:
tH1o
1. Check whether the motor is overloaded.
2. Check whether the rated current of motor (Pr.05-01) is suitable
3. Take the next higher power AC motor drive model.
Motor overheating
The AC motor drive detects that the internal temperature exceeds
Pr.06-30 (PTC level)
tH2o
Corrective Actions:
1. Make sure that the motor is not obstructed.
2. Ensure that the ambient temperature falls within the specified
temperature range.
3. Take the next higher power AC motor drive model.
