Description
The
SetDrivePWM
command is used to set the PWMLimit register, which limits the maximum PWM
duty cycle, and hence the effective output voltage. The PWM limit is applied to each terminal
individually, whether the current loop is enabled or not. The
GetDrivePWM
returns the current value
of the PWMLimit register.
