    Explanation of Terminology Explanation of Terminology The following table explains the terminology related to laser processing. General terms and the terms peculiar to this laser are included. When there is any related page in this Operation Manual, the reference page is shown. Control code that is used for communication between computers.
  • Page 204 Explanation of Terminology Fixed waveform that is a laser light output means to be used by this laser. Laser light with a fixed waveform by up to 3 divisions in the case where output time and the output value are set in the range of the first laser and the third laser.
  • Page 205 Explanation of Terminology General term for diode laser and FC-LD. LD chip Semiconductor laser device. Safety device to shut off the circuit at detection of a leakage current that flows from the power Leakage breaker supply to the ground. Neutral point terminal. This is a terminal to be connected a neutral point of the circuit. Abbrevia- tion of Neutral.
  • Page 206 Explanation of Terminology Pulse width Time during which laser light is irradiated. Maximum effective current value when a current can be continuously output. Rated current This value indicates that it is prohibited to cause a current to continuously flow exceeding this level.
