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 installers documentation for
details.
Even though the system installers 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.
