CNC Treatment of emergency signals
The emergency inputs of the CNC are:
/EMERGEN (M5000)
Physical input coming from the PLC.
/EMERGENCY STOP
Physical input coming from the outside. Pin 10 of connector X2
The emergency outputs of the CNC are:
/ALARM (M5507)
Physical output to the PLC.
/EMERGENCY OUTPUT
Physical output to the outside. Pin 2 of connector X2
There are to ways to cause an emergency at the CNC, by activating the physical input /
EMERGENCY STOP or the general logic input "/EMERGEN" from the PLC.
Whenever any of these signals is activated, the CNC stops the axes feed and the spindle rotation
and it displays the corresponding error message.
By the same token, when the CNC detects an internal malfunction or at an external device, it stops
the axes feed and the spindle rotation displaying at the same time the corresponding error message.
In both cases, the CNC will activate the /EMERGENCY OUTPUT and /ALARM signals to indicate
to the PLC and to the outside world that an emergency has occurred at the CNC.
Once the cause of the emergency has disappeared, the CNC will deactivate these signals to indicate
to the PLC and to the outside world that everything is back to normal.
