A negative response is returned
Cause:
The control method is set to “I/O” in the “System settings”.
Remedy:
• To control laser pumping, the shutter, or the guide laser by
communication commands, select “Communication commands” for
the corresponding operation. A change of this setting will take effect
only after restarting the laser marking system. The setting is required
for the following commands:
Laser pumping (
LSR
)
Shutter control (
SHT
)
Guide laser (
GID
) (except LP-GS052)
• The
SPT
command (laser radiation for measurement) is available
only if “Shutter control” is set to “Communication commands”.
Cause:
Reception mode is OFF.
Remedy:
The setting request of most commands can only be transmitted if
reception mode is ON. Turn on reception mode with the Reception mode
(
MKM
) command. The following commands do not require the reception
mode:
File switching by number (
FNO
)
File switching by name (
FNN
)
Shutter control (
SHT
)
Reception mode (
MKM
)
Laser pumping (
LSR
)
Counter reset (

)
Marking trigger (

)
