Extended FunctionsParking axis and parking sensor4.12 Parking axis and parking sensor4.12.1 DescriptionThe parking function is used in two ways:“Parking sensor”– Monitoring of a certain encoder is suppressed.– The encoder is prepared for the “removed” state.“Parking axis”– Monitoring of all encoders and Motor Modules assigned to the “Motorcontrol” application of a drive are suppressed.– All encoders assigned to the “Motor control” application of a drive areprepared for the “removed” state.– The Motor Module that is assigned the application “Motor control” of drive isprepared for the state “removed Motor Module”.Parking a sensorWhen a sensor is parked, the sensor being addressed is switched to inactive(r0146 = 0).Parking an axisControl is carried out via the sensor control/status words of the cyclic telegram(Gn_STW.14 and Gn_ZSW.14).With a parked motor measuring system, the associated drive must be broughtto a standstill by the higher-level control system (disable pulsese.g. via STW1.0/OFF1). The monitoring functions for the power section remain active (r0126 = 1).When an axis is parked, the power section and all the sensors assigned to the“motor control” are switched to inactive (r0146[n] = 0).Control is carried out via the control/status words of the cyclic telegram(STW2.7 and ZSW2.7) or using parameters p0897 and r0896.0.The drive must be brought to a standstill by the higher-level controller (disablepulses e.g. via STW1.0/OFF1).DRIVE-CLiQ communication to downstream components via the deactivatedpower section (r0126 = 0) remains active.A measuring system that is not assigned to the “motor control” (e.g. directmeasuring system) remains active (r0146[n] = 1). The drive object remains active (r0106 = 1).© Siemens AG 2006 All Rights ReservedSINAMICS S120 Function Manual, 03/2006 Edition4-215
