Subchart A-2: High Performance Operation Using Olv Or Clv - YASKAWA U1000 Series Technical Manual

 Subchart A-2: High Performance Operation Using OLV or CLV
Flowchart A-2 in Figure 4.10
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.

Auto-Tuning 3 (T1-01 = 5)
<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> Run the operation in test mode for Auto-Tuning 3. The drive will automatically set motor parameters automatically. For details, refer to
Stationary Auto-Tuning 3 on page
<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 Feed Forward function.
