It is recommended that the PWM frequency parameter be set
to approximately16 times the maximum output frequency of
the control. The greater the ratio, the more sinusoidal the
output current waveform will be.

Note: The output current rating of the control must be derated for high PWM
frequency operation as follows:
Standard Constant Torque and Standard Variable Torque: Linearly
derate to 10% between 2.5 and 5.0KHz (10% derating at 5.0KHz).
Quiet Constant Torque and Quiet Variable Torque: Linearly derate to
30% between 8.0 and 16KHz (30% derating at 16KHz).
