dynamically change. It is used to store changes through a power loss.

NTC

Negative Temperature Resistor

Option Button

See Radio Button.

Opto-isolated

A method of sending a signal from one piece of equipment to another without the usual

requirement of common ground potentials. The signal is transmitted optically with a light

source (usually a Light Emitting Diode) and a light sensor (usually a photosensitive

transistor). These optical components provide electrical isolation.

Output Function

See source. The terminals at which energy is taken from a circuit or device.

Output Line

The actual transistor or relay controlled output signal.

Parameters

User read only or read/write parameters that indicate and control the drive operation. These

variables generally hold numerical data defined in the Setup Views.

Personal Computer.

Protective Earth.

PID

Proportional-Integral-Derivative. An acronym that describes the compensation structure that

can be used in many closed-loop systems.
