MF-C300A-SF/C500A-SF
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.136
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.136
RxD Pin for received data out of signal lines of the communication connector. → P.136
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.90
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.
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.43
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.139
STX Control code that is used for communication between computers. → P.139
Surge Abnormal overvoltage or overcurrent applied momentarily to the electric circuit. → P.43
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.
TxD Pin for send data out of signal lines of communication connector. → P.136
W
Work distance Distance from the laser light output position to the target workpiece for laser welding.
