DBX21.7 (pulse en‐able)Geometry axis / machine axis Interruption AbortNoteRemoval of the "Controller enable" and "Pulse enable" during traversing results in a rapid stopof the axis and a reset alarm.Interruption of a traversing motionWhen a stop command is issued, the distance-to-go is saved and the handwheel pulses arecollected. When the stop condition no longer applies, the resulting distance is traversed.Abort of a traversing motionWhen a stop command is issued, the distance-to-go is deleted and the handwheel pulses areignored (i.e. not collected) until the stop condition no longer applies.Behavior in the event of a safe operating stopAnalog to the NC/PLC interface stop signals, the behavior in the event of a stop can also beadjusted by activating the safe operating stop (SBH):Stop condition Scope MD20624 $MC_HANDWH_CHAN_STOP_CONDBit 12 == 0 Bit 12 == 1(Default setting)Safe operating stop inthe event of active tar‐get velocity limitMachine axis Interruption AbortIn the default setting, Bit 12 is set to "1", i.e. in the event of a stop resulting from activation ofthe safe stop, current movements are aborted and new handwheel pulses ignored.Prerequisite for an interpolatory stop is an active target velocity limit (i.e., MD36933$MA_SAFE_DES_VELO_LIMIT > 0).H1: Manual traversing17.6 Manual traversing using a handwheelAxes and spindlesFunction Manual, 06/2019, A5E47437747B AA 663
