<1> Only for SINAMICS S120.
<2> Effective ramp-up time: Tup_eff = Tup + (IR/2 + FR/2)
Effective ramp-down time: Tdn_eff = Tdn + (IR/2 + FR/2)
<3> p1151.0 = 0: Rounding-off at zero crossover enabled.
p1151.0 = 1: Rounding-off at zero crossover disabled.
<4> p1134 = 0: Rounding-off is always active.
Overshoots can occur.
p1134 = 1: Final rounding-off is not effective
when the setpoint is suddenly
reduced during ramp-up.
<5> For SERVO and VECTOR, the following applies: Inhibited during jogging.
<6> After a 0/1 signal a ramp-up is started again.
<7> With simultaneous jog 1 and 2 (p1055 = p1056 = 1) the last setpoint remains effective (Freeze ramp-function generator).
<100> For SERVO, the following applies: Only if the function module "extended setpoint channel" is activated (r0108.8 = 1).
<101> To view the pre-assignment of the sampling times in p0115, refer to p0112.
