Power modules: 

• BUS 621 to BUS 624
• 0.8 kW to 20 kW
• The BUS (power modules to be mounted side by side) contain power transistors for the motor and a slot for the controller· 
  

​Supply modules:

• BUG 622 (18kW) and BUG 623 (36 kW) with brake resistor, line rectifier, inrush current limitation, DC link choke and the control circuit for the brake resistor. BUC 624 and BUC 625 with controlled line rectifier for the power recovery of the brake energy from the motor.

BUM 618 for wall mounting
BUM 619 for rack mounting

• Line contactor, supply unit, power unit, and controller unit in one compact drive
• For synchronous motors up to 1.5 kW, line: 3 x 230V
• Position control circuit and electronic gear are integrated  

• The BUB 622 can be connected additionally to the BUG or converters of the BUM series.
• The BUB 622 contains the electronic triggering for an additional brake resistor. The BUR 622 or another, externally mounted resistor can be used as brake resistor.
• When the servo drive is braked, kinetic energy from the motor is fed into the DC link. First, it charges the CD link capacitor. Other, excessive energy is supplied from the power resistor in the BUB 622 to a brake resistor at intervals. The maximal load of the transistor is 75 kW. 

• The BUR 622 is an accessory to the BUB 622.
• It is triggered by the BUS 622 and operates as a brake resistor with a continuous power of 2 kW. Short-term: 18 kW for 15 sec. max and 36 kW for 7 sec. max.
• Using the BUR 622, the servo drive is able to decelerate in a shorter time and more often than would be possible using the resistor in the BUG or BUM on its own. 

• The BUK 622 extends the capacity of the DC link capacitors for the BUG and BUM series.
• If the energy released in the generator (braking) mode of the machine can be used by the machine in the next cycle, the use of the BUK 622 is more efficient than the dissipation of the brake energy in a brake resistor. The brake energy is "temporarily stored" in the BUK 622 and swings between servo motor and BUK. 

The modular design of the software and the software modules which can be linked as necessary, such as adder, multiplier, PI controller, etc. enable sophisticated applications without additional expenditure. The almost unlimited possibilities of internal, free wiring using the new ALINKS from Baumuller form the basis for fast and easy configuration, adapted to special applications.

The ALINKS are configured as necessary using the graphic user interface on the screen, e.g. using the function blocks reverser, filter, setpoint generator, actual value, and others. For customized control, all electronic cards of the Baumuller Omega control can be integrated additionally. This means that the BKD/F is state of the art amang brand new intelligent servo controllers, for a power up to 800 kW.

The BKD/BKF 7000 is designed for a large line supply range from 340 V to 550 V. The 7000 series enables an overload capacity for a shorttherm overload of 120% rated current. DC drives from 5 kW to 800 kW in four-quadrant operation (BKF), or up to 1,100 kW in one-quadrant operation (BKD) can thus be operated. The devices of the 7000 series use their full functionality together with a PLC, NC or CNC. The BKD/F 7000 with its RS 485 interface can be connected to the USS® protocol. The BKD/BKF7000 series can easily be adapted to other bus systems using option cards on the microprocessor board. The CANsync®, Interbus®, and Profibus® systems can be used as bus connections which are already familiar from the Baumuller V-controller. 

DS/HT/DA motors are part of the BMS modular system which has been designed to matched to the digital converters series: BUM (single axis), BKH (single axis with regenerative mains supply) and BUG/BUS (multi-axes-system).

Baumuller is using the modular motor design to provide a component , which adheres precisely to the customers' mechanical, and dynamic,requirements. Even the same mechanical outline allows a variety of cooling and mounting options: the class of protection (IP23 or IP54), the mounting of the motor (B3 feet, B5 flange, V1, etc.), synchronous or asynchronous type, speed and voltage adapted designs, etc.

DS/HT/DA motors cover a power range from 0.41 to 100 kW. Standard rated speeds of 300 rpm'-1 to 6,000 rpm'-1 are available. The frame size ranges from 80 to 160 mm (level of drive-shaft above mounting surface). In conjunction with Baumuller amplifiers all motors can be utilized as direct (gearless) drives. Due to sophisticated and high speed controllers inertia missmatch is no longer a major aspect in motor-load combination. Even critical applications allow the choice of best and cost effective motor size.selection. As a pioneer in the field of gearless drives, Baumuller has completely mastered applications for controlled drives with an inertia of the load being much higher than the one of the motor itself.
