Defines the reference for speed ramp balancing. The output
of the ramp generator is forced to this value when balancing
is enabled by parameter
Speed ramp balancing reference.
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, speed reference 3
