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.H1: Manual and handwheel travel4.6 Handwheel travelExtended FunctionsFunction Manual, 10/2015, 6FC5397-1BP40-5BA3 177
