LOGIC CNC INPUTS AND OUTPUTS.<br />
CNC <strong>8065</strong><br />

Consulting and modifiable signals of the spindle.<br />
Execution channels<br />
speed using the variable "(V.)PLC.S.sn", but without generating a gear change even if the<br />
gear change is automatic (parameter AUTOGEAR).<br />
These M functions are treated the same way as those executed from the CNC. When the<br />
CNC activates one of these marks, the CNC activates the MSTROBE mark and writes the<br />
corresponding M function into the MFUN register. Once the M function has been<br />
synchronized at the PLC (AUX<strong>EN</strong>D signal), the CNC starts sending the velocity com<strong>man</strong>d<br />
to that spindle, updates (refreshes) the M function history and deactivates the mark at the<br />
PLC.<br />
The CNC will admit M functions even if the channel is in execution (executing a program,<br />
jogging an axis, etc.) as long as the channel status is other than "In error" and "Not ready"<br />
and the channel is not doing a reset or validating machine parameters. If during tool<br />
inspection, the PLC changes the turning direction of a spindle using these marks, the change<br />
will be identified when repositioning and will appear as pending to reposition.<br />
The CNC ignores the PLC requests in the following cases, when the CNC ignores the mark<br />
set by the PLC and it erases it so the request does not remain pending.<br />
When the spindle is working as a C axis.<br />
When the spindle is threading (rigid tapping, normal tapping or electronic threading).<br />
When the CNC status is "In error" or "Not ready", is doing a reset or validating parameters.<br />
If the PLC activates these marks while synchronizing another M function of the program<br />
being executed or while homing the spindle, the PLC keeps this mark activated until the CNC<br />
can attend to it.<br />
SLIMITACSPDL<br />
There is a mark for each spindle. The mnemonics for each spindle are the following:<br />
SLIMITACSPDL1 (can also be programmed as SLIMITACSPDL)<br />
SLIMITACSPDL2 SLIMITACSPDL3 SLIMITACSPDL4<br />
If the PLC activates this mark, the CNC activates the speed safety limits (parameter SLIMIT)<br />
on the indicated spindle during the execution of the current block. If the PLC deactivates this<br />
mark, the CNC restores the programmed speed.
