General information on manual and equipment
Meaning
Electromagnetic compatibility
All measures to suppress electromagnetic disturbances
caused by different electrical equipment in the same
electromagnetic environment, and to strengthen the
immunity of the equipment to such disturbances.
ACS2000 and related equipment
Earth
The conducting path (e.g. conductor) between the
electric equipment (e.g. frequency converter) and the
earth. The electric equipment is connected to the earth,
e.g. by a grounding set or a grounding switch.
Input filter unit
The IFU is a tuned filter: inductors, resistors and
capacitors that reduce harmonic voltages injected to the
supply network.
Interface
Inverter unit of the drive. The INU converts the DC
voltage to the required AC motor voltage and frequency.
Term of ABB's I/O system. The I/O module is an active
input or output device for digital or analog signals.
Light emitting diode
RMS voltage of the main power supply of the drive – line
to line
Low voltage
MV switchgear
Medium voltage switchgear isolation device
The MV switchgear is a mandatory inter-connection
device of the drive system and connects / disconnects
the main power supply to the drive. The MV switchgear
must be controlled entirely by the drive.
Neutral point
Printed circuit board
Protective earth
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 AFE and INU of the drive.
Power plate communication system
PPCS is an acronym for a fieldbus communication
protocol designed for high speed data transfer via fiber-
optic cables between the AMC circuit board and phase
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
Short form for terminal entry unit of the drive
