2.1 General
The mono power units BUM 62, BUM 63 and BUM 64 complete the upper power range of the Baumüller
Modular System.
They are produced as compact converter units and contain the mains supply as well as the motor-end
power unit.
The rack-mounted modules of the Baumüller Modular System are designed for control tasks. As a result,
the drives can be adapted to a wide variety of requirements.
There are two types of controller.
The BUS 6 E controller for almost all applications in constructional engineering.
The BUS 6 T controller for highly demanding control tasks.
As both controllers are equipped to be rack-mounted, separate descriptions are available with the re-
spective characteristics and technical data.
Depending on the application, the unit can be delivered in variations from simple frequency converters
to highly dynamic and precise vector controllers.
With the BUM 62, BUM 63 and BUM 64 mono power units, both asynchronous and synchronous mo-
tors with different encoder systems can be driven by the same unit.
2.1.1 Function description
The BUM 62, 63 and 64 units consist of two parts, the supply converter and the motor-end inverter.
y BUM 62:
The supply converter for creation of the intermediate circuit voltage is an uncontrolled diode bridge.
The intermediate circuit capacitors are charged via a charging resistance to reduce peak starting cur-
rent, which is bridged by a thyristor after switching on.
y BUM 63 and 64:
The supply converter is a thyristor bridge. The starting current is limited, on switching on, by con-
trolling the thyristor converter current .
y BUM 62, 63 and 64:
The IGBT motor-side inverter processes the transistor control signals sent by one of the controllers
plugged into the slot, and makes the control measurement signals available. The mono unit has
monitoring facilities of its own (self-protecting power unit).
