Serial Interface Specifications
(8) XYR/XYW (X-axis offset, Y-axis offset, Axial rotation angle)
Read/Write the X-axis offset, Y-axis offset and axial rotation angle for all layout data.
This command can be accepted during marking (ACK is replied) and executed automatically at
the end of marking. (Applies to the next marking.)
■
Write (XYW t0, t1, t2)
t0:
X-axis offset (unit: 1 µm)
t1:
Y-axis offset (unit: 1 µm)
t2:
Axial rotation angle (unit: 0.000001
°
)
(9) LMR/LMW (Laser start)
Read/Write the LD activation status.
In this setting, 0 = OFF and 1 = ON.
(10) MSR/MSW (Marking start)
Read/Write the marking status.
In the read setting, 0 = Finished and 1 = Marking in progress.
In the write setting, 0 = Stop marking and 1 = Start marking.
Writing 1 (to start marking) is valid only under local (internal) control.
Writing 0 (to stop marking) is valid under both local and remote control.
(11) GLR/GLW (Guide beam)
Read/Write the guide beam activation status.
In this setting, 0 = OFF and 1 = ON.
(12) LNR/LNW (Layout number selection)
Read the currently selected layout number.
Also used to change the layout number by writing the specified layout number instead.
(13) RLR/RLW (Toggle external control)
Obtain the current status of the device used for external control.
Also used to switch the control method.
In this setting, 0 = Local (Internal) and 1 = Remote (External).
The following table shows which devices can be used to start marking and select layout
numbers under local and remote control.
･
If XYW commands are accepted several times during marking, the last one will be
effective.
･
The changed offset value is effective until the power supply is turned off. At power
on, the value is 0.
If the guide beam was activated via external I/O, it cannot be deactivated with a
command to set it to 0 (OFF).
