2.2 Mode groups
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:
– A rotating spindle, e.g., a spindle rotating despite RESET.
– An asynchronous reciprocating axis.
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.
1. Before POWER ON, the machine data:
MD10735 $MN_JOG_MODE_MASK (Bit 0)
must be set.
2. The user switches to AUTO
(PLC user interface DB11, ... DBX0.0 = 0→1 edge). "JOG in AUTOMATIC" is then active
if the NCK previously had channel status "RESET" and program status "Aborted" in all
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 (as a concurrent positioning axis), i.e., the PLC has fetched the axis via
axis replacement (e.g., via FC18).
– A command axis, i.e., the axis was programmed by a synchronous action and the
motion has not yet been completed.
mode group channels. The axis in question must also be "jog-capable". DRF must be
deactivated (if not already deactivated).
channels that do not have channel status "Reset" and program status "Aborted".
