A168 [PWM Frequency] Related Parameter(s): A169
Sets the carrier frequency for the PWM output waveform. The chart below provides derating guidelines based on the PWM frequency setting.
Values Default: 4.0 kHz
Min/Max: 2.0/10.0 kHz (Frame C and D drives)
2.0/8.0 kHz (Frame E, F, G and H drives)
Display: 0.1 kHz
IMPORTANT
Ignoring derating guidelines can cause reduced drive performance.
