Initial Pole Detection Method

Sets how the drive detects the position of the rotor when the motor starts.

Determined by A1-02

(0 - 2)

Note:

When you use an SPM motor, set n8-35 = 0. When you use an IPM motor, set n8-35 = 0 to 2.
When you set n8-35 = 1, do High Frequency Injection Auto-Tuning.
When you set n8-35 = 0 or 2, always evaluate the drive with the equipment being used for the application. If the drive incorrectly detects the polarity, the motor can rotate in the direction opposite of the Run command.

0
Pull-in: Starts the rotor with pull-in current.
1
High Frequency Injection: Injects high frequency to detect the rotor position. This setting can cause a loud excitation sound when the motor starts.

Note:
When you set 1, do High Frequency Injection Auto-Tuning.
2
Pulse Injection: Inputs the pulse signal to the motor to detect the rotor position.
