1. Check if the input voltage falls within the rated AC motor
drive input voltage range.
2. Check for possible voltage transients.
3. If DC BUS over-voltage due to regenerative voltage, please
increase the Decceleration Time or add an optional brake
resistor.
1. Check if the input voltage falls within the rated AC motor
drive input voltage range.
2. Check for possible voltage transients.
1. Check if the input voltage is normal
2. Check for possible sudden load
1. Check if the input voltage is normal
2. Check for possible sudden load
1. Check if the input voltage is normal
2. Check for possible sudden load
2. Check for possible sudden load
Check Power Source Input if all 3 input phases are connected
without loose contacts.
For models 40hp and above, please check if the fuse for the AC
input circuit is blown.
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.
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.
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.
Check if the motor is overloaded, if yes, replace with next larger
drive
1. Check whether the motor is overloaded.
2. Check whether motor rated current setting (Pr.05-01) is
suitable
3. Take the next higher power AC motor drive model.
Check Pr.06-61, Pr.06-62, Pr.06-63.
