H1: Manual and handwheel travel 44.1 OverviewApplicationEven on modern, numerically controlled machine tools, a facility must be provided that allowsthe user to traverse the axes manually.Examples:● Setting up the machineEspecially when setting up a new machining program, a manual traversing of the machineaxes is required. Where coordinate offset or rotation is selected, manual travel can evenbe performed in the transformed workpiece coordinate system.● Retraction of the tool after a program abortAfter a program abort due to a power failure or RESET, the operator must manually retractthe tool from its current machining position. The transformations and coordinate systemsused for machining must remain active while this is done.JOG modeManual traversing of axes is performed in JOG mode.If JOG mode is active for the current mode group, this is reported to the PLC via thecorresponding interface signal:DB11 DBX6.2 (BAG1: operating mode JOG)DB11 DBX26.2 (BAG2: operating mode JOG)...DB11 DBX186.2 (BAG10: operating mode JOG)References:Function Manual, Basic Functions; Mode Group, Channel, Program Operation, ResetResponse (K1)DisplayIf JOG mode is active, the basic JOG screen is displayed on the operator interface. This mainscreen contains values relating to position, feedrate, spindle, and tool.Extended FunctionsFunction Manual, 10/2015, 6FC5397-1BP40-5BA3 147
