Acceleration Error

The motor did not accelerate for the specified acceleration time.

  1. Increase the value set in C1-01 [Acceleration Time 1].

  2. Disconnect the machine from the motor and do Rotational Auto-Tuning again.

The value of L7-01 or L7-02 [Forward/Reverse Torque Limit] is small.

Increase the value set in L7-01 or L7-02.

Rotational Auto-Tuning was done with a load that was more than 30% of the rating connected to the motor.

  • Disconnect the machine from the motor and do Rotational Auto-Tuning again.

  • If you cannot uncouple the motor and load, make sure that the load is less than 30% of the motor rating. If a mechanical brake is installed in the motor, release the brake during Rotational Auto-Tuning.
