The system i nstaller 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:
