Pr.67
Skip Frequency 1
Pr.68
Skip Frequency 2
Pr.69
Skip Frequency 3
Settings 0.00 to 400.0 Hz
These three parameters determine the three Skip Frequencies that in conjunction with Pr.70,
Skip Frequency Band, will cause the AC drive to skip operating in each frequency band. Note:
Pr.67 > Pr.68 > Pr.69.
Pr.70
Skip Frequency Band
Settings 0.00 to 20.00 Hz
This parameter determines the frequency band for a given Skip Frequency. Half of the Skip
Frequency Band is above the Skip Frequency and the other half is below. Programming this
parameter to 0.1 disables all skip frequencies.
Pr.71
PWM Carrier Frequency
Settings 115V series
230V series
460V series
575V series 01 to 10 (1KHz to 10KHz)
Note: 1-9kHz in sensorless vector control mode
The parameter defines the carrier frequency of the PWM (Pulse-Width Modulated) output.
