Pull-in Current Switching
Speed
Sets the speed range to operate with the pull-in current command. Drive rated frequency = 100%
value. If there is a large quantity of oscillation when you operate in the low speed range, increase the
setting value.

Initial Pole Detection
Method
Sets how the drive detects the position of the rotor when the motor starts.
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.
