6-3 Sensor Vector Control
Follow the steps below to set the sensor vector control function.
• Sensor vector control parameter settings
• PG Board settings
• Auto-tuning
• Adjustment
• Set the 1st Control Method (A044) to 05 (Sensor vector control).
• Set the 1st Motor Capacity (H003) and the 1st/ Motor Pole Number (H004) according to your motor.
• In the 1st Base Frequency (A003), set the rated frequency of the motor. In the Motor Rated Voltage
Selection (A082), set the rated voltage of the motor.
• Sensor vector control can be used only for the 1st control method.
• Sensor vector control cannot be used in the light load mode.
• In the V2 Control Mode Selection (P012), set the control method used for sensor vector control. You
can select speed control, position control, etc.
