The system installer determines what axes are shared and how a shared
axis is changed from process to process. Using AMP and PAL the system
installer determines the process for a shared axis at power up, control reset,
and E-Stop reset. Refer to your system installer’s documentation for
details.
Even though the system installer’s PAL program determines how and when
a shared axis changes processes, there are some global restrictions that can
not be altered. Before a request to change a shared axes process is
performed, both processes that share the axis must be in one of the
following states:
- E-Stop
- Cycle Stop (not cycle suspend)
- Manual mode with the shared axis not being positioned
- Executing an M99 in a main program
- Postlude State (established through PAL)
Other restrictions are as follows:
If the sharedaxis is currently: Then:
performing a manual motion(including
continuous, incremental, or handwheel jog,
homing, jog on the fly, or angled jogs)
the request to change process for that axisis ignored until the
manual motionis completed
¶
being positioned by thePAL axis mover the request to change processesis ignored until the PAL axis
mover hascompleted movingthe sharedaxis
¶
in the active plane andcutter compensation is
active
the request to change processes is ignoreduntil theplane is
changed or cutter compensation isdeactivated
¶
used to perform CSS calculations(the sharedaxis
has beenassigned asthe CSSaxis andthe
control iscurrently inCSS mode)
the request to change processes is ignoreduntil CSSmode is
canceled
¶
involved in a modal fixed cycle(such asdrilling,
turning, threading, or 7300cycles)
the request to change processes is ignoreduntil thecycle is
canceled
¶
If either processis performing a: Then:
jog retract or block retrace shared axes can not beswitched intoor out of theprocess.
This isindependent of whether the shared axisis involved in
the jog retract or blockretrace operation
¶
program interrupt a shared axis cannot be switchedinto or out of the process
¶
synchronization operation with a synchronization
M--code
a shared axis cannot be switchedinto or out of the process
¶
¶ The request for anaxis tochange processesis ignoreduntil theprohibiting featureis completed or canceled.
Then the change in process onlytakes placeprovided therequest for theaxis change is still true.
