Treatment of emergency signals
7.11 Treatment of emergency signals
The CNC provides the following emergency signals:
/EMERGENCY STOP
Physical emergency input.
It is generated from the outside and corresponds to the physical emergency input.
This signal is active low (0 V).
/EMERGENCY OUTPUT
Physical emergency output.
It is generated internally when an error is detected at the CNC or at the PLC.
This signal is active low (0 V).
/EMERGEN (M5000)
Logic input of the CNC, generated by the PLC.
When the PLC activates this signal, the CNC stops the axis feed and the rotation of the spindle,
and it displays the corresponding error message.
This signal is active low (0 V).
/ALARM (M5507)
Logic input of the PLC, generated by the CNC.
The CNC activates this signal to let the PLC "know" that an alarm or emergency condition has
occurred.
This signal is active low (0 V).
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.
