MOTION CONTROL SYSTEM, MSC-250 USER'S GUIDE
AUGUST 1998 GLOSSARY A - 3
LED: Light-Emitting Diode. Also known as solid-state lamp. A
semiconductor diode that converts electric energy to light.
MSC Toolkit: The personal computer-based software package used to edit,
compile, and debug Macroprograms developed for MSC
controllers.
MSC-850: A multi-axis, programmable, servo motion controller capable of
synchronously controlling from 1 to 8 axes.
Mode: The way in which the MSC-250 executes instructions. It is
determined by the position of a 16-position selector switch.
Most Significant Bit: The bit that carries the greatest value or weight in the binary
notation for a numeral. The left-most bit in the binary word
(notation).
Nonvolatile Memory: A computer storage medium that retains information in the
absence of power.
Optically Isolated: Indicates an I/O which uses a coupling device in which a light-
emitting diode, energized by an input signal, is optically
coupled to a photodetector.
Parameters: Predefined data which is used in the execution of instructions.
Peripheral: Various kinds of devices that operate in combination or
conjunction with the MSC-250 controller but are not physically
part of the controller.
PLC: Programmable Logic Controller.
Position: To move the motor to an absolute position in reference to a
previously established 0.00 point (Home).
Position Error: The difference between the present actuator position
(feedback) and the desired position (command).
Position Feedback: Present actuator position as measured by a position
transducer.
POS OUT: Position Output (motor error output).
