Initial Pole Detection
Method
Sets how the drive detects the position of the rotor at start.
Note:
• When you operate an SPM motor, set n8-35 = 0. When you operate an IPM motor, you can set
n8-35 = 0 to 2.
• When you set n8-35 = 1, doHigh Frequency Injection Auto-Tuning.

HFI Frequency Level for L
Tuning
Sets the injection frequency for high frequency injection.
Note:
• Set n8-35 = 1 [Initial Pole Detection Method = High Frequency Injection] or n8-57 = 1 [HFI
Overlap Selection = Enabled] to enable this parameter.
• The drive automatically calculates this value when High Frequency Injection Auto-Tuning
completes successfully.
