Over-current during acceleration
(Output current exceeds triple rated current during
acceleration.)
Corrective Actions:
1.
Short-circuit at motor output: Check for possible poor
insulation at the output lines.
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.

Over-current during steady state operation
(Output current exceeds triple rated current during constant
speed.)
Corrective Actions:
1.
Short-circuit at motor output: Check for possible poor
insulation at the output line.
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.
