L
LIFO last-in, first-out
limit switch/
end-of-travel position
(input) Sensors that alert the control electronics that physical end of travel is
being approached and that the motion should stop.
M
m meters
MCS move complete status
microstep The proportional control of energy in the coils of a Stepper Motor that
allow the motor to move to or stop at locations other than the fixed
magnetic/mechanical pole positions determined by the motor
specifications. This capability facilitates the subdivision of full
mechanical steps on a stepper motor into finer microstep locations that
greatly smooth motor running operation and increase the resolution or
number of discrete positions that a stepper motor can attain in each
revolution.
modulo position Treat the position as within the range of total quadrature counts per
revolution for an axis.
N
noise An undesirable electrical signal—noise comes from external sources
such as the AC power line, motors, generators, transformers,
fluorescent lights, soldering irons, CRT displays, computers, electrical
storms, welders, radio transmitters, and internal sources such as
semiconductors, resistors, and capacitors. Noise corrupts signals you
are trying to send or receive.
noninverting The polarity of a switch (limit switch, home switch, etc.) in active
state. If these switches are active-high, they are said to have
non-inverting polarity.
