2.3.27 PWM (Pulse-Width Modulation).
PWMOUTPUT
Local digital output associated with the PWM.
Possible values: From 0 to 2.
Default value: 0.
Associated variable: (V.)MPG.PWMOUTPUT
Local digital output associated with the PWM. For the PWM, only local outputs associated
with pins LI/O1 (local output 1) and LI/O2 (local output 2) may be used because they have
been set for Laser applications. That requires setting parameter NLOCOUT = 8.
The output for the PWM and for synchronized switching may be the same one and they may
be used at the same time (same value at parameters SWTOUTPUT and PWMOUTPUT).
However, this configuration is not recommended for certain types of Laser generators.
PWMCANCEL
Cancel the PWM after an M30 or a reset.
Possible values: Yes / No.
Default value: No.
Associated variable: (V.)MPG.PWMCANCEL
This parameter indicates whether the CNC cancels the PWM after executing M02, M30 or
after a reset.
When there is a CNC error in the channel that has the PWM active (or in any channel if it
is managed via PLC), it the parameter is set to "Yes", the CNC deactivates the PWM. If the
parameter is set to "No", the CNC keeps the status of the output; i.e. it does not cancel the
output if it is active. Once the PWM is deactivated for some error, that PWM will not be
reactivated when the error disappears; therefore, they have to be reactivated either by
program or via PLC.
PWMOUTPUT Meaning.
0 PWM missing.
1 Local output 1 (pin LI/O1).
2 Local output 2 (pin LI/O2).
