Can you write to Mxx30? Or does it stay latched?


We don't use the standard M variable definition and I don't have the manuals to hand.


If your referfing to Motor or Coord status register, then yes it stays latched. Actively writing to the register does not clear it.

If lookahead is on when this occurs you can “retrace” the path in the current program with the "<" command or resume forward execution after changing the limit value.


See the section in the TURBO PMAC USER MANUAL on "Position Limits" in the Lookahead section, page 310 (326 electronic) for complete details of this feature.
