Parameters 215
23.28 Variable slope 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 (23.29 Variable slope rate)
are equal, speed reference (23.02 Speed ref ramp output) is
a straight line.
This function is only active in remote control.
Off
Off Variable slope disabled. 0
On Variable slope enabled (not available in local control). 1
23.29 Variable slope rate Defines the rate of the speed reference change when variable
slope is enabled by parameter 23.28 Variable slope.
For the best result, enter the reference update interval into
this parameter.
