LOSSARY
Glossary-vii
A feedback device which is used in a brushless servo
system to provide information for the amplifier to
electronically commutate the motor. The device uses
a magnetized wheel and hall-effect sensors to
generate the commutation signals.
Holding Torque
Sometimes called torque, it specifies the maximum
external force or torque that can be applied to a
stopped, energized motor without causing the rotor to
rotate continuously.
Home Position
A reference position for all absolute positioning
movements. Usually defined by a home limit switch
and/or encoder marker. Normally set at power up and
retained for as long as the control system is
operational.
Host Computer
An auxiliary computer system which is connected to a
controller or controllers. The host computer in
distributed control systems is frequently involved
with controlling many remote and distributed motion
control devices. It may also be used for off-line tasks
such as program preparation, storage, and supervisory
control and evaluation.
HP: Horsepower
One horsepower is equal to 746 watts. Since Power =
Torque x Speed, horsepower is a measure of a
motor's torque and speed capability (e.g. a 1 HP
motor will produce 35 lb.-in. at 1800 rpm).
Hunting
The oscillation of the system response about a
theoretical steady-state value.
Hybrid Stepping Motor
A motor designed to move in discrete increments or
steps. The motor has a permanent magnet rotor and
wound stator. These motors are brushless and phase
currents are commutated as a function of time to
produce motion.
Hysteresis
The difference in response of a system to an
increasing or a decreasing input signal.
I/O: Input/Output
The reception and transmission of information
between control devices. In modern control systems,
I/O has two distinct forms: switches, relays, etc.,
which are in either an on or off state, or analog
signals that are continuous in nature such as speed,
temperature, flow, etc.
Idle Current Reduction
A stepping motor driver feature that reduces the
phase current to the motor when no motor motion
(idle) is commanded for a specified period of time.
This reduces motor heating and allows high machine
throughput to be obtained from a given motor.
Incremental Motion
A motion control term that is used to describe a
device that produces one step of motion for each step
command (usually a pulse) received.
Indexer
Electronics which convert high level motion
commands from a host computer, programmable
controller, or operator panel into step direction pulse
streams for use by the stepping motor driver.
Inertia
The property of an object to resist changes in velocity
unless acted upon by an outside force. Higher inertia
objects require larger torques to accelerate and
decelerate. Inertia is dependent upon the mass and
shape of the object.
Inertial Match
An inertial match between motor and load is obtained
by selecting the coupling ratio such that the load
moment of inertia referred to the motor shaft is equal
to the motor moment of inertia.
