Terminology

Motion control system that utilizes position feedback devices to maintain a mechanical location.

a motor drive that creates sinusiodal motor control currents

Direction that controlled movement occurs. X: Linear motion in positioning direction; Y: Linear motion perpendicular to positioning direction; Z: Vertical linear motion; A: Roll - Angular motion around X; B: Pitch - Angular motion around Y (pitch); C: Yaw -Angular motion around Z

Part of a machine or system that requires a controlled motion

Conductor that passes current from the d.c. motor terminals to the rotating commutator

Motors which utilize electronic switches rather than mechanical brushes.

A servo drive which utilize electronic switches rather than mechanical brushes.

The controller is a device that makes decisions based on the information givenby the host, or user

An electronic device that translates a given command from a motion controller into the electrical current that turns a motor.

A feedback device that translates motion into electrical signals indicative of actuator position.

An open networking standard

The provision of measured information from a system under control to allow a servo loop to be constructed

An overhead framework that is designed to travel linearly in the X, Y, and/or Z axes

An electronic unit that converts high-level commands into step and direction pulses needed by a stepping motor driver

An axis or axes moving to a pre-programmed position, at a defined velocity and acceleration rate

Motion along a straight line, using only one spatial dimension. It can be uniform, that is, with constant speed, or non-uniform, that is, with a variable speed. The motion of a along the line can be described by its position x, which varies with t)

Different configurations of linear motors are available which correspond with brushed, brushless servo or stepper motors

a sub-field of automation, in which the position and/or velocity of machines are controlled using some type of device such as a hydraulic pump, linear actuator, or an electric motor, generally a servo

Open loop control refers to a motion control system with no external sensors . A closed loop control is a motion control system that has position and velocity feedback.

Proportional, integral, derivative. A three mode motion control action where the controller has time proportioning, integral and derivative rate action
