Subchart A-3: Operation with Permanent Magnet Motors
Flowchart A3 in Figure 4.7 describes the setup procedure for running a PM motor in Open Loop Vector Control. PM motors
can be used for more energy-efficient operation in reduced or variable torque applications.
Note: 1. 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.
2. Realign the Z Pulse if the PG encoder is replaced. Set T2-01 to 3 to recalibrate the drive for the new encoder.
