u Subchart A-2: High Performance Operation Using OLV or CLV
Flowchart A2 in Figure 4.6 describes the setup procedure for high-performance with Open Loop Vector Control or Closed
Loop Vector Control, which is 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.
Is the load less than
30% of the rated load
for the motor?

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.

<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 less, though Stationary Auto-Tuning may 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 Ride-Thru
function.
