About this manual
Explanation
Control panel interface board
Branching unit used for making parallel connections for both supply
units and inverter modules
Main voltage measurement board
Control panel
Module interface board
Interface board to the main circuit thyristors and current
measurements
Varistor board
See supply module
The rectifier consists of diodes (or diodes and thyristors).
See supply unit and diode supply module.
Diode supply module
Relates to the construction type of the component in question
For example, several drive types with different power ratings may
have the same basic construction, and this term is used in reference
to all those drive types.
With the ACS800-07 (+V992) (> 500 kW), the frame size of the drive
indicates the quantity and frame size of the supply modules, plus the
quantity and frame size of the inverter modules, eg, "2×D4 + 4×R8i".
To determine the frame size of a drive type, see the rating tables in
the chapter Technical data.
Converter which converts direct current (DC) and voltage into
alternating current (AC) and voltage
Inverter and related auxiliary devices enclosed inside a metal frame
or enclosure
The inverter module is one of the major building blocks in a cabinet-
installed drive.
Inverter module(s) under control of one control board, and the
related auxiliary devices
Typically, one inverter unit controls one motor. There is one inverter
unit in a single drive (such as ACS800-07) and several in a
multidrive installation.
Drive for the control of several motors which are typically coupled to
the same machinery
There are one supply unit and several inverter units in a multidrive.
Satellite board that can be snapped on the RMIO board to add the
number of fibre optic channels available
