LOGIC CNC INPUTS AND OUTPUTS
SOFT: V02.2X
General logic outputs
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.
RAPID (M5516)
The CNC sets this signal high to tell the PLC that a rapid positioning (G00) is being executed.
TAPPING (M5517)
The CNC sets this signal high to tell the PLC that a tapping canned cycle is being executed (G84).
THREAD (M5518)
The CNC sets this signal high to tell the PLC that a threading block is being executed (G33).
PROBE (M5519)
The CNC sets this signal high to tell the PLC that a probing movement is being executed (G75/G76).
ZERO (M5520)
The CNC sets this signal high to tell the PLC that a machine reference search is being executed
(G74).
RIGID (M5521)
This output is only available on the mill model. The CNC set this signal high to indicate to the PLC
that a RIGID TAPPING operation (G84) is being performed.
RETRAEND (M5522)
The CNC sets this signal high to indicate to the "PLC" that while retracing is active all the possible
blocks have been retraced.
For further information, see general input "RETRACE (M5051)".
CSS (M5523)
This output is only available on the lathe model. The CNC sets this signal high to tell the PLC that
the constant cutting speed function is selected (G96).
