INU
Inverter Unit
The INU converts the three DC voltages to the required AC
motor voltage. The unit is designed as a self-
commutated, 3-level voltage source inverter consisting of
three identical power modules.
I/O device
Term of ABB’s S800 I/O system. An I/O device consists of
a module termination unit (MTU) and one I/O module.
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.
I/O station
Term of ABB’s S800 I/O system. The I/O station typically
consists of a bus modem and several input and
output devices.
IOI
Inverter Output Isolator
The IOI is a switching device that disconnects the inverter
from the motor.
IP
Ingress Protection
The IP code specifies the degree of protection provided
by an enclosure.
Line voltage
RMS voltage of the main power supply of the drive
LSU
Line Supply Unit
The LSU rectifies the AC line voltage and supplies the
electrical energy to the DC link capacitors.
MCB
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.
MSM
Main State Machine
MVD
Medium Voltage Drive
