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-Tuning
completes successfully.

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 .

Pull-in/Light Load Id
Current
Sets the d-axis current that flows to the motor during run at constant speed as a percentage where E5-
03 [PM Motor Rated Current (FLA)] = 100%.

Heavy Load Id Current
Sets the d-axis current to that the drive will supply to the motor to run it at a constant speed with a
heavy load. Considers
E5-03 [PM Motor Rated Current (FLA)] to be 100%. Usually it is not
necessary to change this setting.

Pull-in Current @
Acceleration
Sets the pull-in current allowed to flow during acceleration/deceleration as a percentage of the motor
rated current.
Note:
Parameter A1-02 [Control Method Selection] selects which parameter is the motor rated current.
•
A1-02 = 5 [OLV/PM] : E5-03 [PM Motor Rated Current (FLA)]
• A1-02 = 8 [EZOLV] : E9-06 [Motor Rated Current (FLA)]
