„ Response data for laser energy
When the serial data output of laser energy [mJ] is allowed at the power output mode setting, the following response data is
transmitted at the end of the lasing operation (after LASING END OUT turns on).

Total data length
• 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.
• 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.
• If the laser energy is lower than 1000 mJ or the lasing time is shorter than 0.4 second, the measurement results may be
unstable.
• When the trigger mode is set to "Continuous trigger", the response of the laser energy shows the total energy of the all
lasing operation repeated during the period from turning on of TRIGGER IN to turning on of LASING END OUT.
