■ n8-35: Initial Pole Detection Method
No.
(Hex.)
Name Description
Default
(Range)
n8-35
(0562)
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.
■ n8-36: HFI Frequency Level for L Tuning
No.
(Hex.)
Name Description
Default
(Range)
n8-36
(0563)
HFI Frequency Level for L
Tuning
Sets the injection frequency for high frequency injection.
500 Hz
(200 - 1000 Hz)
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.
■ n8-37: HFI Voltage Amplitude Level
No.
(Hex.)
Name Description
Default
(Range)
n8-37
(0564)
Expert
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.
20.0%
(0.0 - 50.0%)
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.
■ n8-39: HFI LPF Cutoff Freq
No.
(Hex.)
Name Description
Default
(Range)
n8-39
(0566)
HFI LPF Cutoff Freq
Sets the low-pass filter shut-off frequency for high frequency injection.
250 Hz
(0 - 1000 Hz)
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.
