S−shaped ramp function generator (SRFG)
Purpose
The function block serves to direct the input signal via a jerk−limited ramp generator (S shape) in order
to avoid setpoint step−changes.

SRFG1−LOAD
l
Via digital input SRFG1−LOAD, the ramp function generator is loaded (set) with the signal from
SRFG1−SET.
l
This value is immediately accepted, i.e. there is no acceleration/deceleration via S shape (the
output skips to this value).
l
As long as SRFG−LOAD = HIGH, the ramp function generator remains inhibited.
