Cause : Control Fault comes when the torque limit was reached continuously for three seconds after the Stop command was input and deceleration was not possible in OLV Control.

1. Motor parameters are set improperly.

• Check the motor parameter settings and repeat Auto-Tuning.

2. Torque limit is too low.

• Set the torque limit to the most appropriate setting (L7-01 through L7-04).

3. Load inertia is too big.

• Adjust the deceleration time (C1-02, C1-04, C1-06, C1-08).
• Set the frequency to the minimum value and interrupt the Run command when the drive finishes decelerating.
