Travel commandDepending on the setting in machine data MD11324$MN_HANDWH_VDI_REPRESENTATION (see Section "Parameter assignment(Page 173)"), the following interface signal is output to the PC already when a travel requestis present or not until the axis moves:● Machine axes:– DB31, ... DBX64.6 (minus travel command) or– DB31, ... DBX64.7 (plus travel command)● Geometry axis 1:– DB21, … DBX40.6 (geometry axis 1: Minus travel command) or– DB21, … DBX40.7 (geometry axis 1: Plus travel command)● Geometry axis 2:– DB21, … DBX46.6 (geometry axis 2: Minus travel command) or– DB21, … DBX46.7 (geometry axis 2: Plus travel command)● Geometry axis 3:– DB21, … DBX52.6 (geometry axis 3: Minus travel command) or– DB21, … DBX52.7 (geometry axis 3: Plus travel command)● Orientation axis 1:– DB21, … DBX332.6 (orientation axis 1: Minus travel command) or– DB21, … DBX332.7 (orientation axis 1: Plus travel command)● Orientation axis 2:– DB21, … DBX336.6 (orientation axis 2: Minus travel command) or– DB21, … DBX336.7 (orientation axis 2: Plus travel command)● Orientation axis 3:– DB21, … DBX340.6 (orientation axis 3: Minus travel command) or– DB21, … DBX340.7 (orientation axis 3: Plus travel command)NoteA travel command set in JOG mode is canceled if the controller enable or pulse enable for theaxis to be traversed is missing. The travel command must therefore be set again after releaseof the axis.Invert handwheel direction of rotationThe handwheel direction of rotation can be inverted, if the direction of movement of thehandwheel does not match the expected direction of motion of the axis. The adaptation canbe especially necessary, if a handwheel (HT2, HT8) can be assigned to various axes.H1: Manual and handwheel travel4.6 Handwheel travelExtended Functions170 Function Manual, 10/2015, 6FC5397-1BP40-5BA3
