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%)
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.
