/ALARM (M5507)
The CNC sets this signal low in order to tell the PLC that an alarm or emergency condition has been
detected. This signal will be set high once again, once the message from the CNC has been
eliminated and the cause of the alarm has disappeared.
Likewise, while this signal is low, the CNC keeps the emergency output (pin 2 of connector X2) active
(low).
MANUAL (M5508)
The CNC sets this signal high to tell the PLC that the JOG (Manual) operating mode is selected.
AUTOMAT (M5509)
The CNC sets this signal high to tell the PLC that the automatic operating mode is selected.
MDI (M5510)
The CNC sets this signal high to tell the PLC that the MDI mode (manual data input) is selected
in one of the operating modes (JOG, automatic, etc).
SBOUT (M5511)
The CNC sets this signal high to tell the PLC that the single block execution mode is selected.
INCYCLE (M5515)
The CNC sets this signal high while executing a block or moving an axis.
Once the execution of the program has been requested by the PLC to the CNC by means of the
logic input CYSTART, the latter will indicate that it is being executed by setting the INCYCLE signal
high.
This signal is maintained high until the CNC finishes the part program or when this is stopped by
means of the STOP key on the CONTROL PANEL or the general logic input /STOP.
If the CNC is in the single block execution mode, the INCYCLE signal is set low as soon as the block
execution is concluded.
If the CNC is in JOG mode, the INCYCLE signal is set low as soon as the position indicated has
been reached.
If the CNC is in JOG mode and the axes are being jogged, the "INCYCLE" signal goes high while
any of the jog keys are pressed.
Example
/ALARM AND (other conditions) = O1
The emergency output O1 of the PLC must be normally high. If an alarm or an emergency
is detected at the CNC, the emergency output O1 must be set low (0V).
