System Functions
Pr.67 Pr.68 Pr.69 Pr.70
Skip Frequencies 1 to 3 Setting
Parameter # 67, 68, 69
Parameter Name Skip frequency 1, 2, 3
Factory Setting d000.0 Hz
Units 0.1 Hz
Parameter value d000.1 - d400.0 Hz
This parameter determines the three skip frequencies, which in conjunction with
Pr.70 [Skip Frequency Band] will cause the AC drive to skip operation at these
frequency ranges. (See graph below)
Parameter # 70
Parameter Name Skip frequency band
Factory Setting d000.1
Units 0.1 Hz
Parameter value d000.1 - d020.0 Hz
This parameter determines the frequency band of a given [Skip frequency]. The
actual band is 2 x Skip frequency band, half of which is above and the other half is
below the [Skip frequency] setting. Setting this parameter to 0.1 to disable all skip
frequencies. (See graph below)
