Explanation of Terminology
Sequencer
A type of PLC (Programmable Logic Controller) that exerts sequence control by executing the
programmed contents of control, being a product name of Mitsubishi Electric Corporation.
SI
Optical fiber type that is used in this laser. Abbreviation of Step Index. The SI type is one of
multi-mode optical fibers (MMF: Multi Mode optical Fiber) in which the refractive index distribution
in the core is uniform. The index means the refractive index. → P.68
Single phase
Electric current whose magnitude and direction change periodically, having the same phase.
This single phase is used as a 100 V power supply for electric lamps and plug sockets.
sq (square) Unit that represents a sectional area of cable. Square millimeter. → P.47
Start bit
Bit to indicate the beginning of data in the asynchronous communication mode in which
synchronization is performed for each data such as control character and symbol. The bit to
indicate a separation between characters is called stop bit. → P.153
STX Control code that is used for communication between computers. → P.157
Surge Abnormal overvoltage or overcurrent applied momentarily to the electric circuit. → P.47
T
3-phase
Current composed of a set of 3 alternating currents with a phase difference of 120º. This current
is mainly used for a power of business use.
Timesharing
Laser light delivery specification. When the incorporated timesharing unit is operated, laser light
is output to a single optical fiber. This function is provided in the timesharing specification of this
laser. → P.104
Timesharing unit
Unit that mounts mirrors to reflect laser light. Laser light is output to the selected optical fiber
when the mirror is operated. This unit is incorporated in the laser oscillator section according to
the timesharing specification of this laser. → P.35
TxD Pin for send data out of signal lines of communication connector. → P.152
U
Ultra pure water
Water whose purity is unlimitedly close to the ideal water H
2
O with a purity of 100%. This water
is treated by a combination of strictly quality-controlled ion-exchange resin, active carbon,
membrane filter, UF, UV, etc. As standard, when the resistivity is 16 to 17 Ω-cm or more, the
water is called pure water.
Y
YAG rod
This means a laser medium that is excited by flashlamp, which is composed of a transparent
crystal which is made by adding Neodymium (Nd3+) to Yttrium-Aluminum-Garnet. This rod is
inserted in the laser chamber in this laser. → P.22 and P.35
W
Work distance Distance from the laser light output position to the target workpiece for laser welding.
