2.6 Operation of table data for pulse power feedback
Table data for actual power presumption that are used for pulse power feedback by actual
power presumption method can be referred and input.
Pushing soft-key [PWR.FB] with setting 1 to parameter No.29000#1(PTB) makes displaying
pulse power feedback screen.
Please refer to specification (A-78991) for details of Pulse power feedback by actual power
presumption method.
2.7 Measuring a time constant of laser power sensor
A time constant of laser power sensor can be automatically measured in power sensor time
constant measurement screen.
Pushing soft-key [PW SNS] with setting 1 to parameter No.2900#2 (PTC) makes displaying
power sensor measurement screen.
CNC measures an actual delay time by measuring a power sensor output with output laser
and sets the time to the parameter as a time constant.
In practical, beam stops after running beam with shutter closed for a set time by a set power
and CNC measures the time that a monitored power of power sensor is down.
The measured time is set in parameter No.29005 as the time constant of linear delay filter.
2.7.1 Sequence of time constant measurement
Pushing soft-key [STRT] in time constant measurement screen or setting PMC signal
PTCMR to 1 makes start of measuring.
Push soft-key [QUIT] or set PMC signal PTCMR to 0 in order to quit the measurement.
Pushing soft-key [(OPRT)] in time constant measurement screen makes displaying soft-key
[STRT] and [QUIT].
A peak laser power should be set in parameter No.29003 because of a rated power is different
for each type of oscillator.
And beam output time should be set in parameter No.29004.
A beam is internally run with shutter closed in case of satisfying following conditions.
• Laser sequence No. (Diagnose No.908) is 30.
• Shutter lock is ON. (*SHTLC signal is 0.)
• Shutter is closed.
• Beam is not output.
• Alarm does not occur.
Present status can be confirmed in power sensor time constant measurement screen.
