at SRFG1-OUT; SRFG1-DIFF remains on 0 %
SRFG1-OUT O - - - - Output is limited to ±100 %
SRFG1-DIFF O - - - - Output is limited to ±100 %, outputs the acceleration of
the ramp function generator
SRFG1-LOAD
z Via the digital input SRFG1-LOAD the ramp function generator is loaded with the signal of
SRFG1-SET (set).
z This value is accepted immediately , i.e. no acceleration or deceleration via an S shape takes
place (the output jumps to this value).
z As long as SRFG-LOAD = HIGH, the ramp function generator remains inhibited.
