ML-2550A/2551A
Peak power
At laser welding, the peak power means the energy amount per time (value resulting from
dividing the pulse energy by pulse width) and its unit is watt (W).
Peak value
Laser output peak value. "PEAK POWER" value that is set on the SCHEDULE screen in this
laser. → P.65
Photo MOS relay
Full solid relay that adopts a light emitting diode on the driving side and MOS (Metal-Oxide
Semiconductor) FET (Field-Effect Transistor) for the contact. → P.132
PLC
Device that exerts sequence control by executing the programmed contents of control in
sequence. This is often called Sequencer (product name of Mitsubishi Electric Corporation).
Abbreviation of Programmable Logic Controller.
Powersharing
Laser light delivery specification. Single laser light is split into multiple beams by beamsplitter so
that laser light is output simultaneously to multiple optical fibers. → P.104
pps Number of pulses per second. Abbreviation of pulse per second.
Protective glasses
Protective glasses that the operator puts on to protect the eyes from laser light. The protective
glasses are divided into some types by wavelength of laser light.
Pulse width Time during which laser light is irradiated.
Purified water
Water that has been purified by distillation, filtration, or deionization. Water whose electric
resistivity is 1 to 3 MΩ-cm. For cooling water of this laser, deionized or purified water is used.
R
Rated current
Maximum effective current value when a current can be continuously output.
This value indicates that it is prohibited to cause a current to continuously flow exceeding this
level.
Remote interlock
Interlock function to shut off the laser output in an emergency as a means for using the laser
device safely. In this laser, the REMOTE INTERLOCK connector is connected to the door of the
room so that laser light may be shut off when the door is opened. → P.128
Resistivity
Electric resistance generally used as a scale to indicate the hardness of current flow for a
material. Its unit is ohm (Ω). The value that indicates this resistance by unit volume (1 cm x 1 cm
x 1 cm) is volume resistivity and its unit is ohm centimeter (Ωcm).
Resonator mirror
Mirror composing resonators in the laser oscillator section. The light that has been excited by
laser chamber is amplified between 2 resonator mirrors into a laser beam. → P.33
Resonator shutter
Resonator provided in the laser oscillator section. When this shutter is closed, no laser light is
output though the flashlamp comes on. → P.35
RS-232C
Serial communication standard that is standardized by Electric Industries Alliance (EIA) of the
United States. This is used for a connection between a data line terminator such as MODEM and
a data terminal unit such as PC. Many different devices are based on this standard, so that this
standard is used for various fields. Abbreviation of Recommended Standard-232C. → P.146
RS-485
Serial communication standard that is standardized by Electric Industries Alliance (EIA) of the
United States. RS-485 meets the requirement for multi-connection for multiple units of up to 32
units by bus type multi-point connection. Abbreviation of Recommended Standard-485. → P.146
RxD Pin for received data out of signal lines of the communication connector. → P.146
S
SCHEDULE
This word means a laser light output schedule in this laser. Thirty-two types of SCHEDULE can
be set and each schedule can be registered with a SCHEDULE number. → P.78
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.
