Product Details

Baumuller BUS25-30/60-30-001, short marked as 25-30/60-30-00 1, is a heavy-duty servo drive power unit belonging to Baumüller BUS25 legacy servo series. This baumuller power unit converts three-phase AC input into adjustable variable three-phase output to drive matched Baumüller AC servo motors, supporting torque, speed and position closed-loop control for high-demand automated machinery. It integrates IGBT power switching components, DC link bus, built-in dynamic braking circuit, current and voltage sensing, and thermal detection. The unit is fitted with heavy-duty power terminals for mains, motor and brake resistor wiring, together with signal terminals for control and feedback connection. Front LED indicators clearly display power status, running activity and fault alarm codes for quick on-site diagnosis. The internal PCB adopts conformal coating to resist dust and moisture, allowing this bus25 servo drive to sustain continuous cyclic load inside industrial electrical cabinets. As a scarce discontinued original spare, this servo drive power stage serves as a drop-in replacement to restore high-performance motion output for ageing Baumüller production lines.

Supported Functions

This bus25 servo drive performs high-power energy conversion for the servo motion system. The baumuller power unit receives motion setpoints and real-time encoder feedback signals, dynamically adjusting output current to maintain stable torque, velocity and precise positioning. This servo drive power stage supports jog operation, homing routine, electronic gearing and soft limit monitoring to protect mechanical structures from overtravel damage. It continuously monitors internal temperature, DC bus voltage and output current; once values exceed safe thresholds, it triggers fault lockout and cuts off power output to prevent component burnout. It stores fault history codes to facilitate troubleshooting and transmits alarm signals to upper-level PLC or HMI. It works perfectly with compatible BUS25 control boards, Baumüller servo motors, encoder assemblies and feedback cables to build a complete closed-loop motion control system.

Core Functions

As the power core of the BUS25 servo platform, this bus25 servo drive delivers high dynamic adjustable power required by heavy-duty servo motors. Its comprehensive onboard protection circuits reduce the risk of damage under overload and unstable mains conditions, and the standardized BUS25 architecture simplifies direct replacement during equipment maintenance. This baumuller power unit works as a direct spare to rebuild reliable high-current servo driving capability for legacy Baumüller automation equipment.
