◆ Subchart A-2: High Performance Operation Using OLV or CLV

Subchart A-2 describes the setup procedure when using Open Loop Vector Control or Closed Loop Vector Control.
Vector control is appropriate for applications requiring a 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.
