MF-C2000A Series
Explanation of Terminology
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.172
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.172
RxD Pin for received data out of signal lines of the communication connector. → P.172
S
SCHEDULE
This word means a laser light output schedule in this laser. 256 types of SCHEDULE can be set
and each schedule can be registered with a SCHEDULE number. → P.106
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.
sq (square) Unit that represents a sectional area of cable. Square millimeter. → P.52
Start bit
Bit to indicate the beginning of data in the asynchronous communication mode in which synchro-
nization is performed for each data such as control character and symbol. The bit to indicate a
separation between characters is called stop bit. → P.155
STX Control code that is used for communication between computers. → P.175
Surge Abnormal overvoltage or overcurrent applied momentarily to the electric circuit. → P.51
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.24
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.
TxD Pin for send data out of signal lines of communication connector. → P.172
W
Work distance Distance from the laser light output position to the target workpiece for laser welding.
