Definition
Electrical-optical interface
Frequency converter and related equipment
The excitation unit (EXU) is part of the drive when a synchronous
motor has to be supplied with excitation power.
Earth
To connect the electrical equipment to the earth, eg, by a grounding
set or a grounding switch.
Term of ABB's S800 I/O process system. An I/O device consists of a
module termination unit (MTU) and one I/O module.
Term of ABB's S800 I/O process system. The I/O module is an active
input or output device for digital or analog signals.
Term of ABB's S800 I/O process system. The I/O station typically
consists of a bus modem and several input and output devices.
Integrated gate-commutated thyristor
Insulated power supply
Light emitting diode
Line supply unit (rectifier phase module)
The main circuit breaker (MCB) is a major protection device of the
drive system and connects and / or disconnects the main power
supply to the drive.
This is the customer terminal for connecting motor cables. It is
located behind the swing frame of the COU compartment.
Neutral point
Optical-electrical interrupter
A primary phase converter unit (PCU) consists of a transformer
terminal section, a rectifier stack, a DC link and an inverter stack.
A secondary phase converter unit consists of a DC link and an
inverter stack.
The phase module is a compact assembly of wired components
including power semiconductors and circuit boards that serves as
a standardized building block for the inverter and rectifier stack.
