4.1 Design
The BM3200, BM3300 device series are servo converters of Baumüller Nürnberg GmbH.
The devices consist of a power unit and a controller unit, which are integrated in a com-
mon housing. The rated current of the devices reaches from 5 A to 10 A. The devices dif-
fer in size, power and equipment (hard- and software). Variants see ZType code– from
page 53. Devices BM3000 are supply units.
The devices BM3000, BM3200, BM3300 are part of the Baumüller device series b maXX
and can be interconnected with other Baumüller devices.
The device series b maXX mainly consists of 2 systems:
Module system consisting of a supply unit and of one or several axis units.
m Su
pply unit
This is a mains rectifier-/active mains rectifier unit for the supply of axis units via the DC-
link.
The AC voltage at the three-phase system is converted from the input sided mains recti-
fier unit into DC voltage. The DC-link capacitors smooth this DC-link voltage. Additionally
the active mains rectifier unit can regenerate excess braking energy as sinusoidal current
into the power supply.
m Axis unit (with c
ontroller)
This is a motor power inverter, which is supplied from the DC-link via a mains rectifier- or
a active mains rectifier unit.
The output sided inverter generates a three-phase current system with a variable fre-
quency and voltage for the supply of the connected motor.
The controller part controls the inverter of the power unit. The controller is operated either
by an operating software or by a superordinated control.
NOTE!
A de
vice of the series BM3000 is a mains rectifier unit.
NOTE!
A device of the series BM3200, BM3300 can be operated as an axis unit.
NOTICE!
A proper operation of the BM3200, BM3300 as an axis unit, can be guaranteed at
Baumüller mains rectifier units. An operation on active mains rectifiers is forbid-
den.
The mains rectifier unit must be supplied by a TT- or TN-network.
