1. Check for possible motor overload.
2. Check electronic thermal overload setting.
3. Use a higher power motor.
4. Reduce the current level so that the drive
output current does not exceed the value set by
the Motor Rated Current Pr.07.00.
1. Reduce the motor load.
2. Adjust the over-torque detection setting to an
appropriate setting (Pr.06.03 to Pr.06.05).
Please contact the Gefran Technical Assistance.
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 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. 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.
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.
