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.
PC
Personal Computer.
PE
Protective Earth.
PID
PLC
Programmable Logic Controller. Also known as a programmable controller, these devices are used for machine control and sequencing.
