LOGIC CNC INPUTS AND OUTPUTS.
(REF: 1402)
General modifiable signals.
If the program is interrupted (STOP) or no program is in execution (channel in READY state),
the execution of the subroutine depends on parameter SUBINTSTOP. Also, in order to
execute the subroutine when no program is in execution, the channel must be in automatic
mode; the subroutine cannot be executed from jog mode.
The execution of an interruption subroutine may be interrupted with a STOP, but not by
another interruption subroutine. When a subroutine is interrupted, it is not possible to get
into tool inspection mode.
The CNC cancels the mark when it starts executing the subroutine or when it rejects the
execution of the subroutine.
PWMON
This mark may be used to activate and deactivate the PWM via PLC. The PWM is configured
using the following variables.
Activating the Laser via PLC has priority over activating it from the CNC.
The modifications to the PWM both via program or via PLC are updated (refreshed) without
waiting for the PWM cycle in progress to be completed and as continuously as possible with
respect to the previous conditions; in other words, it does not wait for the default signal to
set to zero or to one in each change.
During tool inspection, the CNC does not deactivate the PWM This mark may be used to
deactivate the PWM viaPLC during tool inspection and resume the PWM at the end of the
inspection.
Variable. Meaning.
(V.)PLC.PWMFREQ Frequency of the PWM (between 2 and 5000 Hz; by default, 0).
