Flowchart A2 in Figure 4.9
Closed Loop Vector Control. Appropriate for applications requiring high starting torque and torque limits.
Note: Although the drive sets parameters for the PG encoder during Auto-Tuning, sometimes the direction of the motor and direction
of the PG get reversed. Use parameter F1-05 to switch the direction of the PG so that it matches the motor direction.
Figure 4.9
Run the motor without load; check the rotation direction and operation.
Verify external signal commands to the drive work as desired.
<1> The load must be decoupled from the motor to properly perform Rotational Auto-Tuning.
<2> Rotational Auto-Tuning can still be performed if the load is 30% or less, though Stationary Auto-Tuning will probably yield better control
performance.
<3> Make sure the motor and load can run freely, i.e., if a brake is mounted, make sure it is released.
<4> ASR Gain Tuning automatically performs Inertia Tuning and sets parameters related to Feed Forward and the KEB function.
