BUG 3/2/20 Basic Feed Unit 5
Baumüller Nürnberg GmbH 5.96064.02
2 TECHNICAL DATA
2.1 General
The motor and the converter must be matched to one another to be able to fulfil the requirements
made of the drive system three-phase current servo motor and the converter. Our BAUMOTRONIC
converters, which have been specially developed for servo drives, are transistor converters for four-
quadrant operation.
The BAUMOTRONIC converter system is of modular structure and comprises the following units:
− the BUG basic feed unit
− the BUS servo power unit
The BUG 2/3/20 named basis feed units are mains-side power converters for feeding the BUS 3/21/20
drive amplifiers. They have a ballast circuit to dissipate the drive´s breaking energy. They are available
with internal ballast resistor or, as E version with a connector for external resistors.
Features:
− BUG 3 basic unit for up to 10.5 kW
− BUG 2 basic unit for up to 18 kW
− BUG 20 basic unit for up to 36 kW
− Connection using a pre-transformer of 400 V/230 V 3 ∼
− Servo power units' current supplied from the intermediate circuit
− Switching power supply with wide voltage range continues to be ready-for-use while the inter-
mediate circuit is charged
− Ballast circuit with high peak power integrated in the basic feed unit
