D
DAC digital-to-analog converter
DAQ data acquisition
dedicated Assigned to a particular function.
DGND Digital ground signal.
digital I/O port Group of digital input/output signals.
DIP dual inline package
DLL dynamic link library—Provides the API for the motion control boards.
drive Electronic signal amplifier that converts motor control command signals
into higher-voltage signals suitable for driving motors.
DSP digital signal processor
E
encoder A 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
filter parameters Indicates the control loop parameter gains (PID gains) for a given axis.
filtering A type of signal conditioning that filters unwanted signals from the signal
being measured.
flash ROM Type of electrically reprogrammable read-only memory.
