Corrective Actions
1. When the external input terminal (B.B) is
active, the AC motor drive
Output will be turned off.
2. Deactivate the external input terminal
(B.B) to operate the AC motor drive
again.
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 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 samll: 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 factory.
Return to factory.
1. Press RESET key to set all
parameters to factory.
2. Return to factory.
