General machine parameters.
SYNCHRONIZED SWITCHING.
SWTOUTPUT
Local digital output associated with synchronized switching.
Possible values: From 0 to NLOCOUT (Number of local digital outputs).
Default value: 0.
Associated variable: (V.)MPG.SWTOUTPUT
Local digital output associated with synchronized switching. For synchronized switching,
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.
Synchronized switching refers to the process to control a local digital output of the CNC
depending on the type of movement programmed on the axes. The selected digital output
is activated when switching from G0 to G1/G2/G3. The selected digital output is canceld
when switching from G1/G2/G3 to G0.
In order for this feature to work better, the parameters of the axes involved in the movements
must be set with the same values (gain, filters, acceleration and deceleration, feed forward,
etc.) and must also work with the least amount of following error (lag) as possible.
SWTDELAY
Delay of the device associated with synchronized switching.
Possible values: From 0 to 100 ms.
Default value: 0.
Associated variable: (V.)MPG.SWTDELAY
This parameter sets the delay between digital output on/off and the device that is connected
to it.
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 SWOUTPUT 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

0 PWM missing.
1 Local output 1 (pin LI/O1).
2 Local output 2 (pin LI/O2).
