Corrective Actions
1.
Short-circuit at motor output: Check for
possible poor insulation at the output lines.
2.
Torque boost too high: Decrease the torque
compensation setting in Pr.07.02.
3.
Acceleration Time too short: Increase the
Acceleration Time.
4.
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 line.
2.
Deceleration Time too short: Increase the
Deceleration 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 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.
1.
When multi-function input terminals (MI3-MI9)
are set to external fault, the AC motor drive
stops output U, V and W.
2.
Give RESET command after fault has been
cleared.
Return to the factory.
Return to the factory.
1.
Press RESET key to set all parameters to
factory setting.
2.
Return to the factory.
1.
Press RESET key to set all parameters to
factory setting.
2.
Return to the factory.
Return to the factory.
