7.7.4.2 Setpoint smoothening
For applications, when new setpoints are preset by an external control within xed time base there is one
additional function for the acceleration torque pre-control: the setpoint smoothening.
without setpoint smoothening
(Parameter oP.74 „setpoint smoothening“ = 0: off)
A high precontrol value is calculated at every new
setpoint step without setpoint smoothening. The
precontrol function cannot be used.
with optimal setpoint smoothening
(Parameter oP.74 „reference splitting“ = cycle time of
the external setpoint setting in ms)
The speed setpoint is smoothed, the precontrol va-
lue remains constant.

with reference splitting and variable clock time of the external control
The longest clock time (in ms) must be entered in parameter oP.74 "reference splitting" for optimal precon-
trol at non-constant cycle time of the external control.
This causes a short delay of the reference value, but also a smoother precontrol value.
