Term of ABB's S800 I/O system. An I/O device consists of a module termination unit
(MTU) and one I/O module.
Term of ABB's S800 I/O system. The I/O module is an active input or output device for
digital or analog signals.
Term of ABB's S800 I/O system. The I/O station typically consists of a bus modem and
several input and output devices.
RMS voltage of the main power supply of the drive
Main circuit breaker
The MCB is a major protection device of the drive system and connects / disconnects the
main power supply to the drive. The MCB is controlled entirely by the drive.
Term of ABB's S800 I/O system. The ModuleBus is an electrical bus for the
interconnection of I/O devices.
Module termination unit
The MTU is a passive component containing the process terminals and a section of the
ModuleBus.
Printed circuit board
Point of common coupling. The PCC is the point in the electrical power supply system
where the responsibility of the utility changes to the industrial customer. The utility is
responsible to provide clean voltage and current concerning harmonic distortion up to the
PCC. The industrial customer is responsible not to distort voltage and current by its
electrical systems.
Protective earth
The power cell is an assembly of wired components including power semiconductors and
circuit boards that serves as a standardized building block for the rectifier and inverter of
the drive.
Power plate communication system
PPCS is an acronym for a serial communication protocol designed for data transfer via
optical fibers between AMC circuit board and INTerface circuit boards.
Resistance temperature detector or device
The RTD is a temperature sensor where the change in electrical resistance is used to
measure the temperature.
ABB synonym for uninterruptible power supply
Indicates the operating condition of a circuit or device.
Software
The S800 I/O is a distributed process input output system that can be connected to
various process controllers from ABB and other companies.
Short form for terminal compartment of the drive
Used in the manual to indicate that the drive has reached the value "zero speed" that is
set in a parameter. The value can be set in the range of 0 and maximum speed (the unit
for the speed is rpm).
