Fault Descriptions
1. Short-circuit at motor output: Check for possible poor
insulation at the output.
2. Acceleration Time too short: Increase the Acceleration Time.
3. AC motor drive output power is too small: Replace the AC
motor drive with the next higher power model.
1. Short-circuit at motor output: Check for possible poor
insulation at the output.
2. Decceleration Time too short: Increase the Decceleration
Time.
3. AC motor drive output power is too small: Replace the AC
motor drive with the next higher power model.
1. Short-circuit at motor output: Check for possible poor
insulation at the output.
2. Sudden increase in motor loading: Check for possible motor
stall.
3. AC motor drive output power is too small: Replace the AC
motor drive with the next higher power model.
Return to the factory
When (one of) the output terminal(s) is grounded, short circuit
current is more than 50% of AC motor drive rated current, the
AC motor drive power module may be damaged.
NOTE: The short circuit protection is provided for AC motor
drive protection, not for protecting the user.
1. Check the wiring connections between the AC motor drive
and motor for possible short circuits, also to ground.
2. Check whether the IGBT power module is damaged.
3. Check for possible poor insulation at the output.
Return to the factory
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.
