27 Troubleshooting
E775 Cause:
Unable to transmit the response data of the Marking end verification
(MST) command.
Remedy:
• When the marking interval is too short for the transmission of the
MST command, the command cannot be used. In this case, confirm
the completion of the marking process by I/O signals.
• Check the operation logic of the external control.
E780 Cause:
• LP-GS, LP-RC, LP-RF: The serial numbers of the connected laser
head and controller are different.
• LP-RV: The serial numbers of the connected laser head, oscillator
and controller are different.
Remedy:
• LP-GS, LP-RC, LP-RF: It is recommended to use a laser head and a
controller with the same serial number.
• LP-RV: It is recommended to use a laser head, oscillator and
controller with the same serial number.
E781 Cause:
• The laser head and the controller do not match.
• The signal cable or unit power cable is not connected correctly.
Remedy:
• We recommend that you connect a laser head and a controller which
have identical serial numbers.
• Check the connection of cables and signal lines, and restart the laser
marking system.
E782 Cause:
The GSD file version is incorrect.
Remedy:
To use PROFINET, download the GSD file (XML file) that matches the
controller version of your laser marking system. If the GSD file version is
wrong, settings from the PLC cannot be imported correctly by the laser
marking system.
Applies to LP-RF, LP-RV only.
