2 TECHNICAL DATA
2.1 General
The basic units BUG 622 and BUG 623 are basic supply units for the DC link supply of the power mod-
ules BUS 62x.
For control tasks controller modules for Baumüller power units are available. Thus the units can adapted
to a wide variety of requirements.
There are two types of controller.
The BUS 6 V controller for highly demanding control tasks
BUS 6 M controller for highly demanding multi axis tasks
With the digital drive controllers of the BUS 6 series, both asynchronous and synchronous motors with
different encoder systems can be driven by the same unit.
The basic supply units are divided into two classes, 18 kW and 36 kW.
The basic supply units without return feed are designed for wide range voltage connection between
400 - 460 V (for units of development stages 000, 001, 100, 110) or 400 - 480 V (for all other develop-
ment stages) ± 10 %, 50/60 Hz. Starting current load relief and DC link reactor are integrated into the
unit.
The basic supply units may contain a ballast circuitry to convert the drives brake energy. There are units
available in version E for connection of a external resistance (see type code).
An external extra low voltage 24 V
DC
(SELV / PELV) is neccessary for operating.
