Error description
ME-LPM-SSM-10
Measures
• Set the moving direction to "still" in the trigger
setting.
• Select 2D setting with overall (general)
condition.
When not using the displacement sensor:
Connect the attached displacement sensor
input connector to the back of the controller.
The connector must be connected even when
the displacement sensor is not being used.
When using the displacement sensor:
• Confirm the displacement sensor and
measurement status and eliminate the cause
of the error.
• Confirm the displacement sensor specifications
and adjust to output the correct error signal.
• Check the displacement sensor power supply.
• Check the displacement sensor error signal
terminal wiring.
• If the error signal is not used, short circuit the
displacement sensor input connectors 1 and 2.
• Reduce marking contents and measure
marking time.
• Speed up scan speed.
Turn ON the laser pumping and after the laser
pumping has completed, start marking.
Turn ON the laser pumping and after the laser
pumping has completed, start power check.
Check the thresholds (upper and lower limit) of
the marking energy.
• Change marking timing so that trigger input is
performed after marking ready output is turned
on.
• Check wiring and control procedure for input
terminal, wiring to communication port, and the
procedure of the communication command.
• Check the wiring of the laser stop 1 input
terminal and contact of the switch.
• Confirm operation logic of connection device.
Delete any one of these functions from the file.
Set the character that can be converted into 2D
code.
