SRFG1-LOAD
l The ramp generator is loaded (set) with the signal of SRFG1-SET via the digital input
SRFG1-LOAD.
l This value is immediately accepted, i.e. there is no S-shaped acceleration or deceleration (the
output jumps to this value).
l As long as SRFG-LOAD = HIGH, the ramp generator remains inhibited.
Function
The maximum acceleration and the jolt can be adjusted separately.
