Product Description:

The DKR02.1-W200N-BA01-01-FW is a drive controller manufactured by Bosch Rexroth Indramat and supplied in the DKR Drive Controllers series. It is intended for axis drives that require continuous regenerative torque and real-time velocity control in heavy machining centers, gantry systems, and high-speed packaging lines. Operating between the facility DC supply and the three-phase motor windings, the unit processes setpoints from a master motion controller and modulates current to keep the mechanical load synchronized with programmed positions and cycle times. This arrangement lets the controller regulate motor current directly while maintaining stable motion during changing load conditions.

The drive exchanges reference values through an integrated analog interface, allowing voltage or current signals from legacy CNC systems to command torque or speed directly. Thermal energy is removed by a built-in air blower, so cabinet airflow planning remains simple. The unit is part of Line 02 and is supplied as Version 1. Position data from the motor is accepted as digital servo and resolver feedback, allowing either incremental digital encoders or analog resolvers to close the speed and position loops without external signal converters. This feedback flexibility supports machines that use either resolver-based motors or digital feedback devices on the same control platform.

On the power side, the controller operates without a brake chopper, so regenerative energy must be handled elsewhere in the DC bus system. It is intended for systems in which returned energy is managed by the larger drive installation rather than by an internal braking circuit. Application parameters are assigned under Function Code 01, and the unit uses Function Version 01. These codes indicate the configured control option used by the drive and distinguish this control arrangement from other versions in the product line.
