Meaning
Control unit used for controlling drives, inverters and converters via fiber optic
links.
Short form for ACS580MV frequency converter.
Control unit
Short form for control compartment of the drive.
Distributed Drive Control System
DDCS is an acronym for a serial communication protocol designed for data
transfer via optical fibers.
Short form for ACS580MV frequency converter.
The drive system includes all equipment used to convert electrical into
mechanical power to give motion to the machine.
DriveStartup guides step by step through the complete commissioning including
reporting.
Frequency converter and related equipment.
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.
Electrostatic discharge
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.
Inverter Unit
The INU converts the DC voltage to the required AC motor voltage and
frequency.
Insulated Gate Bipolar Transistor
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.
Printed Circuit Board
