LOGIC CNC INPUTS AND OUTPUTS.
(REF: 1402)
General modifiable signals.
OVRCAN
There is a mark for each channel. The mnemonics for each channel are the following.
OVRCANC1 (can also be programmed as OVRCAN)
OVRCANC2 OVRCANC3 OVRCANC4
If the PLC sets this mark high (=1), the CNC applies 100 % override to the axis feedrate
regardless of the value currently selected. While the OVRCAN mark is high (=1), the CNC
channel will apply 100% of the feedrate corresponding to each work mode.
LATCHM
With this mark, it is possible to select how the JOG keys will work in JOG mode.
• If this mark is low (=0), the axes will move while the corresponding JOG key kept pressed.
• If it is high (=1), the axes will move from the instant the JOG key is pressed until the
software limits are reached or the [STOP] key is pressed or another JOG key is pressed
(in this case the new axis will start moving).
RESETIN
There is a mark for each channel. The mnemonics for each channel are the following.
RESETINC1 (can also be programmed as RESETIN)
RESETINC2 RESETINC3 RESETINC4
With an up-flank, (0-to-1 transition), the CNC channel assumes the machining conditions
selected by machine parameter and it activates the RESETOUT mark. See "RESETOUT"
on page 288.
The treatment of this mark is similar to that of the [RESET] key.
AUXEND
There is a mark for each channel. The mnemonics for each channel are the following.
AUXENDC1 (can also be programmed as AUXEND)
AUXENDC2 AUXENDC3 AUXENDC4
It is used when executing the auxiliary functions M and S. It works as follows:
1 The CNC channel indicates to the PLC, in registers MFUN and SFUN of the channel,
the functions that it must execute and it activates the MSTROBE or SSTROBE mark to
start the execution.
2 The PLC, when detecting that one of these marks has been activated, it must cancel the
AUXEND mark to let the CNC know that the execution begins.
3 Once the required auxiliary functions have been executed, the PLC must activate the
AUXEND mark to let the CNC know that the execution has ended. The AUXEND mark
must be kept high (=1) longer than the time period established by (g.m.p.) MINAENDW.
4 After this time, the CNC deactivates the corresponding SSTROBE or MSTROBE mark
thus ending the execution of the function.
