Features of JOG in AUTOMATIC
• The +/– keys cause a JOG movement, and the mode group is switched internally to JOG.
• Moving the handwheels causes a JOG movement, and the mode group is switched
• An ongoing JOG movement is not complete until the end position of the increment has
• Without any JOG movement, "JOG in AUTOMATIC" responds in the same way as
• If JOG movement is active, the NCK is internally in JOG mode, and, thus, a block search
• While a mode group axis is being traversed in JOG mode, the mode group remains
• Axis replacement is not possible for an axis with active JOG movement. (The axis might
• The PLC user interface indicates "Automatic" mode:
• In "JOG in AUTOMATIC", the PLC user interface displays whether the mode group is in
• In "JOG in AUTOMATIC", the PLC user interface displays whether the NCK has

In this way an increment can be stopped using Stop and then moved to the end using
Start. The NCK remains in "Internal JOG" during this time. A partial increment is possible,
but it must not be interrupted using Stop. There is a mode in which releasing the travel
