LOGIC CNC INPUTS AND OUTPUTS
SOFT: V02.2X
Spindle logic inputs.
ELIMIS (M5456) Main spindle
ELIMIS2 (M5481) Second spindle
If the PLC sets one these signals high, the CNC does not display the corresponding spindle but
keeps controlling it. Same as when setting axis parameter DFORMAT (P1) =4.
This mark can be activated and deactivated at any time and it also cancels the feedback alarms
which the machine parameter does not do.
When the spindle is controlled via Sercos and the PLC sets this signal high, the commands to park
the axis are generated automatically via Sercos. The drive of that spindle will not issue, for example,
when removing the feedback, the CNC will not issue a feedback error.
PLCM3 (M5070) PLCM4 (M5071) PLCM5 (M5072) Main spindle
PLCM3SP2 (M5073) PLCM4SP2 (M5074) PLCM5SP2 (M5075) Second spindle
These marks may be used to execute functions M3, M4 and M5 from the PLC. Executing these M
functions from the PLC is similar to doing it from the main channel; i.e. besides acting upon the
spindle command, it changes the execution history.
The same PLC operation that handles the execution from the main channel also serves for this
execution mode, that does it through PLC marks.
The names of the marks of the first spindle will be as follows:
• To execute function M3: PLCM3.
• To execute function M4: PLCM4.
• To execute function M5: PLCM5.
When having two spindles, the marks of the first spindle will be called in one of the following ways:
• To execute function M3: PLCM3 or PLCM3SP1.
• To execute function M4: PLCM4 or PLCM4SP1.
• To execute function M5: PLCM5 or PLCM5SP1.
The marks of the second spindle will be called as follows:
• To execute function M3: PLCM3SP2.
• To execute function M4: PLCM4SP2.
• To execute function M5: PLCM5SP2.
