Product Description:
The DKR03.1-W200B-BE30-01-FW belongs to the DKR Drive Controllers series produced by Bosch Rexroth Indramat. It is a digital intelligent AC drive controller that converts three-phase mains power into variable-frequency output for induction or servo motors used in industrial automation. The unit integrates power electronics, feedback evaluation, and an internal brake resistor, so a separate braking module is not required. Through the SERCOS interface, it exchanges velocity, torque, and positioning data with higher-level motion controllers for coordinated multi-axis applications. This integrated layout keeps the cabinet arrangement simpler and reduces the need for additional braking hardware beside the controller.
At a 4 kHz switching frequency, the drive supplies a continuous current of 92 A, which supports mechanical loads that demand sustained torque. Its silicon power section can continuously furnish 35 kW of electrical output, while short-term overloads are handled by a peak capability of 141 A. The power stage is designed for a mains range of 3 x AC 400 to 480 V ± 10%, and the logic circuitry is energized from an auxiliary supply of AC 230 V ± 10%. The W200 designation places the unit in the 200 A current class, and an internal bleeder diverts regenerated energy into the built-in resistor whenever the DC link rises above its threshold. Thermal losses are removed by forced-air cooling that uses an integrated blower to keep semiconductor temperatures within safe limits.
The brake resistor can dissipate 1 kW continuously and absorb up to 150 kWs of braking energy during rapid deceleration cycles. Overall heat produced by the power devices and control electronics reaches 1200 W, which helps with cabinet ventilation planning. Mechanical handling is straightforward because the drive weighs 49 kg. Digital servo and resolver feedback channels permit mixed-encoder operation, so the controller can work with different motor feedback devices without a separate interface module. The controller is in line series 03 with design version 1 and function module version 01.
