Cause Corrective Action
• Increase the acceleration time C1-01.
• Check the torque limits L7-01 and L7-02.
• Increase the acceleration time (C1-01).
• If possible, disconnect the load.
• Check the wiring.
• Make sure, that the drive rating fits to the motor.
• Check the load. (Auto-Tuning should have been performed
without the load connected.)
• Replace the drive.
• Check all wiring and correct any mistakes.
• Double check the motor rated current value that was entered
to T1-04 for Auto-Tuning.
• Check the motor rated current value written on the motor
nameplate and enter the correct value.
• Check the V/f pattern setting.
• Perform Auto-Tuning without the load connected.
• Check the input data and repeat Auto-Tuning.
• Check the input data.
• Check the motor wiring.
• Perform Auto-Tuning without load connected.
Check the input data and repeat tuning.
• Make sure the data entered for Auto-Tuning is correct.
• Execute Rotational Auto-Tuning instead. If not possible, try
Stationary Auto-Tuning 2.
• Double check the data that was entered for the Auto-Tuning
process.
• Check the motor and motor cable connection for faults.
Double check the data that was entered for the Auto-Tuning
process.
• Check and correct faulty motor wiring.
• Double check the data that was entered for the Auto-Tuning
process.
