JOG in AUTOMATIC details
JOG in AUTOMATIC mode is permitted if the mode group is in RESET state and the axis is
jog-capable.
RESET for the mode group means:
• All channels in RESET state.
• All programs interrupted.
• No DRF channel active.
Jog-capable axis means:
• The axis is not:
Note: The "jog-capable" property is independent of the "JOG in AUTOMATIC" function.
Activation:
The "JOG in AUTOMATIC" function can be activated using machine data
MD10735 $MN_JOG_MODE_MASK.

2. The user switches to AUTO (PLC user interface DB11.DBX0.0 = 0→1 edge). "JOG in
3. RESET is initiated or the running program is finished with "M30/M2" in all mode group
4. The relevant axis is made "Jog-capable" (e.g., axis replacement PLC→NCK).
Note: In most applications, the axes to be traversed are "JOG-capable" and switching to
AUTO will also activate "JOG in AUTOMATIC"!

– A PLC axis (concurrent Pos axis), i.e., the PLC has fetched the axis via axis
replacement (e.g., FC18).
– A command axis, i.e., the axis was programmed by a synchronous action and the
motion has not yet been completed.
– A rotating spindle, e.g., a spindle rotating despite RESET.
– An asynchronous reciprocating axis.
