262 Parameters
23.28 Variable slope
enable
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, the resulting 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
Other [bit] Source selection (see Terms and abbreviations on page 148). -
23.29 Variable slope rate Defines the rate of the speed reference change when variable
slope is enabled by parameter 23.28 Variable slope enable.
For the best result, enter the reference update interval into
this parameter.

2…30000 ms Variable slope rate. 1 = 1 ms
23.39 Follower speed
correction out
Displays the speed correction term for the load share function
with a speed-controlled follower drive.
See section Load share function with a speed-controlled
follower (page 69).
This parameter is read-only.
