A standard protocol, analogous to RS-232, for
transmitting digital information. The G.P.I.B. interface
(IEEE-488) transmits data in parallel instead of serial
format. (See IEEE-488)
Comparison or ratio of the output signal and the input
signal. In general, the higher the system gain, the higher
the response.
Actual distance between graduations on an encoder.
Feedback device (HED) used in a brushless servo system
to provide information for the amplifier to electronically
commutate the motor.
Hall Effect Device. (See Hall Effect Sensors)
Human Machine Interface. Used as a means of getting
operator data into the system. (See MMI)
Reference position for all absolute positioning
movements. Usually defined by a home limit switch
and/or encoder marker.
A sensor used to determine an accurate starting position
for the home cycle.
A component of bidirectional repeatability. Hysteresis is
the deviation between actual and commanded position
and is created by the elastic forces in the drive systems.
Input / Output. The reception and transmission of
information between control devices using discrete
connection points.
A set of codes and formats to be used by devices
connected via a parallel bus system. This standard also
defines communication protocols that are necessary for
message exchanges, and further defines common
commands and characteristics. (See G.P.I.B.)
A move referenced from its starting point (relative
move).
The physical property of an object to resist changes in
velocity when acted upon by an outside force. Inertia is
dependent upon the mass and shape of an object.
The deviation of a lead screw or ball screw from its
nominal pitch.
A device for translating rotary motion into linear motion.
Unit consists of an externally threaded screw and an
internally threaded carriage (nut). (See Ball Screw)
