Product Description:

The DKR03.1-W200N-BE12-01-FW is a DKR Drive Controllers unit from Bosch Rexroth Indramat. It converts three-phase mains power into regulated DC power and then modulates that energy through its inverter stage to supply controlled current to brushless servo motors in heavy-duty automation systems. This arrangement lets the controller respond to changing load conditions during acceleration, deceleration, and steady-speed operation without losing precise current control. In multi-axis machines, the closed-loop design supports coordinated motion, stable speed regulation, and repeatable positioning for demanding servo applications. It is suited for applications that require consistent torque delivery while multiple axes run under synchronized control.

This controller exchanges real-time process data through the SERCOS interface, allowing deterministic command and feedback cycles with higher-level control systems. Internal heat is removed by a built-in air blower, so the unit can be panel mounted without an external liquid-cooling circuit. Its power section has no bleeder, and braking energy is returned through a rigid DC bus instead of being dissipated in a brake chopper. That arrangement supports systems that manage regenerated energy on the shared DC link. Motor position signals are accepted as digital servo and resolver feedback, so the drive can operate with either high-resolution encoders or conventional resolver transducers.

The unit has Design version 1, which identifies the first mechanical and electronic release of this housing and power section. It also has Function numeric version 01, which marks the assigned function version used for this controller type. Within the product coding structure, it belongs to Line series 03, placing it in the corresponding product generation for related option cards, power cables, and auxiliary modules. These identifiers help distinguish this controller configuration from other versions in the broader product line.
