DDCS Distributed Drive Control System
DDCS is an acronym for a serial communication protocol designed for data
transfer via optical fibers.
Drive Short form for ACS580MV frequency converter.
Drive system The drive system includes all equipment used to convert electrical into
mechanical power to give motion to the machine.
DriveStartup DriveStartup guides step by step through the complete commissioning including
reporting.
Equipment Frequency converter and related equipment.
EMC 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.
ESD Electrostatic discharge
Ground Earth
To ground 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.
INU Inverter Unit
The INU converts the DC voltage to the required AC motor voltage and
frequency.
IGBT Insulated Gate Bipolar Transistor
Line voltage RMS voltage of the main power supply of the drive.
MCB 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.
