„ Response data for laser power
When the serial data output of laser power [W] is allowed at the power output mode setting, the following response data is
transmitted during the lasing operation at the setting intervals (10 ms or 100 ms).

• Laser energy and laser power monitoring function do not provide the warranty of the quality of the laser processing
results. It is not possible to detect the defect in the laser processing quality caused by the external factors.
• The response data for laser power is transmitted only during the lasing operation.
• This response data is transmitted automatically regardless the setting or status of the external control device.
• This response data is transmitted automatically regardless the remote mode ON/OFF state of the laser welding machine.
• This response data is transmitted to the all lasing operation including test lasing and laser radiation for measurement.

• Indicates if the measurement result
of the laser power is in the preset
threshold or not.
• If the warning threshold is not
specified, this response data is
always "0": Normal.
• If the laser power is measured at the
laser off moment such as the interval
of scanning lines, the measured
results become invalid at the warning
threshold detection and this response
data is always "0": Normal.
If the laser power is measured at the
laser off moment such as the interval
of scanning lines, the measured laser
power may be low.
