No.
Off / uint32
Activates the variable slope function, which controls
the slope of the speed ramp during a speed reference
change. This allows for a constantly variable ramp rate
to be generated, instead of just the standard two
ramps normally available.
If the update interval of the signal from an external
control system and the variable slope rate (
) are equal, the resulting speed
reference (
) is a straight
line.
