DLL dynamically-linked library—provides the API for the motion control
boards.
drivers Software that communicates commands to control a specific motion
control board.
DSP digital signal processor
E
encoder Device that translates mechanical motion into electrical signals; used
for monitoring position or velocity in a closed-loop system.
encoder resolution The number of encoder lines between consecutive encoder indexes
(marker or Z-bit). If the encoder does not have an index output the
encoder resolution can be referred to as lines per revolution.
F
f farad
FIFO first-in, first-out
filtering A type of signal conditioning that filters unwanted signals from the
signal being measured.
flash ROM A type of electrically reprogrammable read-only memory.
following error
trip point The difference between the instantaneous commanded trajectory
position and the feedback position.
FPGA field programmable gate array
freewheel The condition of a motor when power is de-energized and the motor
shaft is free to turn with only frictional forces to impede it.
full-step Full-step mode of a stepper motor—for a two phase motor this is done
by energizing both windings or phases simultaneously.
