W7B ASD Installation & Operation Manual
PWM Carrier Frequency
Program  Special  Carrier Frequency
This parameter sets the frequency of the pulse width modulation signal
applied to the motor.
Note: The maximum Carrier Frequency setting allowed is 5.0 kHz for
the following ASDs:
460 Volt  200 HP – 800 HP.
575 Volt  150 HP – 400 HP.
The maximum Carrier Frequency setting allowed for all other ASDs is 15
kHz.
Setting the Carrier Frequency above the Derate Threshold frequency (as
listed below) for a given ASD will reduce the capability of the ASD.
