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.

HFI Voltage Amplitude
Level
Sets the high frequency injection amplitude as a percentage where 200 V = 100% for 200
V class drives and 400 V = 100% for a 400 V class drives. Usually it is not necessary to
change this setting.
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.

HFI LPF Cutoff Freq
Sets the low-pass filter shut-off 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-

HFI P Gain
Sets the response gain for the high frequency injection speed estimation.
Note:
• Set n8-35 = 1 [Initial Pole Detection Method = High Frequency Injection] or n8-57
= 1 [HFI Overlap Selection = Enabled] to enable this parameter.
• When A1-02= 6 [Control Method Selection = AOLV/PM] and you do High
Frequency Injection Auto-Tuning, the drive automatically sets this parameter .
