<4> For SERVO and VECTOR, the following applies: Inhibited during jogging.

<100> For SERVO, the following applies: Only if the function module "extended setpoint channel" is activated (r0108.8 = 1). For r0108.8 = 0, [3095] applies for the generation of the speed limits.
<100>
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.
