Corrective Action
Re-enter the data and repeat Auto-Tuning.
• Check the wiring.

with the load decoupled from the motor.
and
Repeat the Auto-Tuning.
• Check the input data.
• Check the wiring.
• Re-enter the data and repeat the Auto-Tun-
ing.
• 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 con-
nected).
• Replace the drive.

• Perform Auto-Tuning without the load con-
nected.
• Check the input data and repeat Auto-Tuning.
