Effective ramp-up time: Tup_eff = Tup + (IR/2 + FR/2)
Effective ramp-down time: Tdn_eff = Tdn + (IR/2 + FR/2)
Rounding-off is always active.
Overshoots can occur.
Final rounding-off is not effective
when the setpoint is suddenly
reduced during ramp-up.
Inhibited during jogging.

With activated Technology controller (p2200 > 0, p2251 = 0) the ramp-function generator is bypassed (r2349.5).
