The correspondingdigital I/Os are used for drive enables and drive feedbacksignals.PROFIBUS DP - Connection of drive systems to SIMOTION C - Schematic representationSIMOTION CSpeed SetpointConverter Motor / EncoderActual ValueEnable Signals/Feedback SignalsMCFunctionsInterpolator+-PositionControllerDSCn-Controllerl-ControllerPowerSectionRotorPositionG_PM10_en_00055• Coupling via PROFIBUS DP enables the drive system andSIMOTION to exchange all of their data over this link. Isochronousoperation on PROFIBUS DP (PROFIdrive, version 3,isochronous operation) ensures synchronized communicationbetween SIMOTION and the drive.• This type of connection allows all parameter data of the driveto be exchanged over PROFIBUS DP. This also allows commissioning,testing and diagnostics without having to reconnectcables.• To achieve higher dynamics, shorter response times to faultsand reduce the following error, the function DSC (DynamicServo Control) can be used. The position controller is executedin the drive with the same frequency as the speed controller(e. g. in 125 µs).8Siemens PM 10 · 20058/57
