Definition
Ingress Protection
The IP code specifies the degree of protection provided
by an enclosure.
RMS voltage of the main power supply of the drive
Line Supply Unit
The LSU rectifies the AC line voltage and supplies the
electrical energy to the DC link capacitors.
Main Circuit Breaker
The MCB is a major protection device of the drive and the
main connection and disconnection point between the
main power supply and the drive.
Model predictive pulse pattern control
Main State Machine
Medium Voltage Drive
Fast I/O module
DDCS branching unit
Monitoring and diagnostics tool that allows access to the
drive from any location in the world via a secure
Internet connection.
Neutral Point
The term refers to the neutral point of the DC link
Pulse encoder interface module
Pulse Amplifier Interface board
Printed Circuit Board
Protective Earth
Ground bus for the connection of the ground cable
Power Feed Forward
Power Failure
Power Ground
Ground bus for the connection of cable shields
The phase module is a compact assembly of wired
components including the power semiconductors that
serves as a standardized building block for the ARU, LSU
and INU of the drive.
Power Operation Mode
Power Plate Communication Circuit
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
