<1> Inhibited during jogging.
<2> After a 0/1 signal the ramping is re-started.
<3> With activated Technology controller (p2200 > 0, p2251 = 0) the ramp-function generator is bypassed (r2349.5).
<4> With simultaneous jog 1 and 2 (p1055 = p1056 = 1) the last setpoint remains effective (Freeze ramp-function generator).
<5> Value range and/or factory setting depend on Power Module.
