Run the motor without load; check the rotation direction and operation.
Verify external signal commands to the drive work as desired.
Run the operation in test mode for Auto-Tuning 3.
Connect the load to the motor.
Perform ASR gain tuning.

Is the load less than
30% of the rated load

<1> Decouple the load from the motor to properly perform Rotational Auto-Tuning
<2> Rotational Auto-Tuning can still be performed if the load is 30% or smaller, though Stationary Auto-Tuning may yield better
control performance.
<3> Run the operation in test mode for Auto-Tuning 3. The drive will set motor parameters automatically. Refer to Stationary Auto-
Tuning 3 on page 161 for details.
<4> Make sure the motor and load can run freely, i.e., if a brake is mounted, make sure it is released.
<5> ASR Gain Tuning automatically performs Inertia Tuning and sets parameters related to the Feed Forward function.
