Parameters 225
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.
This function is only active in remote control.
Off
Variable slope disabled.
0
On
Variable slope enabled (not available in local control).
1

Defines the rate of the speed reference change when variable
slope is enabled by parameter
.
For the best result, enter the reference update interval into
this parameter.
