Retrace-in-progress signal RVSL<F044#2>
[Classification] Output signal
[Function] Notifies the PMC that retrace is in progress.
[Operation] This signal turns to "1"when:
- Tool is in retrace with the retrace signal RVS turned to "1".
This signal turns to "0"
- The tool is in forward or re-forward with the retrace signal RVS
turned to "0".
- The tool is at stop because of no block to retrace during retracing.
When the tool is in retrace, the M functions, S functions, T functions,
and second auxiliary functions are executed in the same way as when
the tool is moving forward. During retrace, this signal can be used on
the PMC, if required, to prevent these functions from being executed in
the same way as when the tool is moving forward.
Particularly when an M function, S function, T function, or second
auxiliary function is specified in a block containing a move command,
the positions where the code signals and strobe signal are output differ,
depending on whether the tool is in forward (or re-forward) or retrace.
So, take action on the PMC by using this signal and distribution end
signal DEN as required.
