2.3.26 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 canceled
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 ms.
Associated variable: (V.)MPG.SWTDELAY
This parameter sets the delay between digital output on/off and the device that is connected
to it.
SWTG0FEED
Observe the G00 feedrate during the synchronized switching.
Possible values: Yes / No.
Default value: Yes.
Associated variable: (V.)MPG.SWTG0FEED
The SWTG0FEED parameter determines the feedrate for the sections in G0.
The behavior can be modified from the part program with the instruction #SWTOUT. If
according to the parameter or the command (#SWTOUT) the G0s are executed as G1
(constant feedrate), G0 is displayed in the history.
SWTG0FEED Meaning.
Yes Movements in G0 are carried out at a rapid feedrate
(parameter G00FEED).
No The cut is made at a constant feedrate (with the feedrate of
the previous G1/G2/G3), without accelerating in the
sections in G0. This option makes it possible to prevent
possible problems with machine frequency excitation, thus
producing better quality precision and surface cuts.
