Inverter unitINU

Converts direct current and voltage to alternating current and voltage.Inverter

Inverter bridge, related components and drive DC link capacitors enclosed in a metal

frame or enclosure. Intended for cabinet installation.

Inverter module

Inverter module(s) under control of one control board, and related components. One

inverter unit typically controls one motor.

Inverter unit

Drive for controlling several motors which are typically coupled to the same machinery.

Includes one supply unit, and one or several inverter units.

Multidrive

In the drive control program, user-adjustable operation instruction to the drive, or

signal measured or calculated by the drive.

In some (for example fieldbus) contexts, a value that can be accessed as an object,

eg, variable, constant, or signal.
