PWM threshold
speed
The StealthChop feature will be switched off
when the actual velocity is higher than this value.
It will be switched on when the actual velocity is
below this value (and parameter #187 is greater
than zero).

PWM gradient
Velocity dependent gradient for PWM amplitude
(StealthChop). Setting this value to 0 turns off
StealthChop.

PWM
amplitude
Maximum PWM amplitude when switching to
StealthChop mode. Do not set too low. Values
above 64 recommended.

PWM scale
Actual PWM amplitude scaler (255=maximum
voltage). In voltage mode PWM, this value allows
to detect a motor stall.
