NOTE
 Notethatthefiltersnotonlyhaveaneffectontheamountbutalso
onthephaseofthefrequencyresponse.Atlowerfrequencies
higher-orderfilters(PT3,PT4)shouldnotbeused,asthephase
withinthecontrolbandwidthisnegativelyinfluenced.
 ThecoefficientscanalsobespecifieddirectlyviaparameterP 327
- CON_SCON_FilterPara.Theytakeeffectdirectly,sochanging
themisonlyrecommendedwhenthecontrolisswitchedoff.
 Alargebandwidthwillresultinalowerattenuationofthecut-off
frequency.

7.4.3AnalysisofSpeedcontrol
The speed controller is executed as a PI controller. The gain (P-component) and the
integral-action time (I-component) of the individual controllers are programmable.
In order to optimize the speed control loop, two rectangular reference steps are
preset. For automatic controller optimization the step response and transfer function
wizards are available.
