Behavior In Automatic, Mda And Jog Modes - Siemens SINUMERIK 840D Function Manual

Note
If the following axis is not enabled for travel, it is stopped and is no longer synchronous.

Behavior in AUTOMATIC, MDA and JOG modes

Effectiveness
A master value coupling is active depending on the settings in the part program and in the
following machine data:
MD20110 $MC_RESET_MODE_MASK (definition of initial control settings after RESET / TP
End)
MD20112 $MC_START_MODE_MASK (definition of initial control system settings with NC-
START)
Manual mode
Once a master axis coupling has been activated, traversal of the master axis (e.g. with rapid
traverse or incremental dimension INC1 ... INC10000) results in a movement of the slave axis,
allowing for the curve table definition.
Referencing
A master value coupled-following axis should be referenced prior to activation of the coupling.
A following axis cannot be referenced when the coupling is activated.
Deletion of distance-to-go
When deletion of distance-to-go is performed for a leading axis, all axes in the associated,
activated master value coupling are shut down.
Basic setting after POWER ON
No master value couplings are active after POWER ON. (Options with ASUB).
Behavior after NC start/RESET
The following behavior results, depending on the settings of the machine data:
MD20110 $MC_RESET_MODE_MASK (bit 13) (definition of initial control settings after
RESET / TP End)
