The Bosch Rexroth R911286532 (DKR04.1-W400E-BE32-01-FW) is a drive controller from the DKR series, intended for controlling and monitoring electric motors in conjunction with actuators and sensors. It supports a three-phase supply voltage of 400 to 480 VAC (±10%), features a line code of 4 and design code 1, and is rated for 400 A current with a 282 A peak. Bleeder configuration uses an external bleeder with brake chopper and rigid DC bus. Command interface is SERCOS, and feedback options include both digital servo and resolver feedback. The device incorporates a built-in air blower for cooling and is suitable for operation in temperatures from 5°C to 45°C. Installation is required within a control cabinet, following the grounding scheme in the connection diagram, and the controller must be operated only by trained personnel to avoid hazardous movements related to control faults.

Frequently Asked Questions

What is the primary function of the motor control in Bosch Rexroth Indramat DKR04.1-W400E-BE32-01-FW for resolver feedback systems?

The motor control ensures synchronization between digital servo inputs and resolver signals, thereby maintaining accurate shaft positioning during load changes in industrial drive systems.

What rated conditions must the motor withstand in Bosch Rexroth Indramat DKR04.1-W400E-BE32-01-FW at 400A operation?

The motor must tolerate continuous current stress at 400A, with frequency modulation between 50–60 Hz, ensuring stable conduction under continuous industrial workloads.

What role does the motor feedback resolver play in Bosch Rexroth Indramat DKR04.1-W400E-BE32-01-FW drive circuits?

The resolver generates analog sinusoidal outputs proportional to rotor position, enabling accurate motion control integration with the digital servo control architecture.

How does the motor connection to Bosch Rexroth Indramat DKR04.1-W400E-BE32-01-FW interact with SERCOS interface?

The motor connection communicates motion commands and feedback digitally through the SERCOS protocol, offering deterministic data exchange for synchronized multi-axis applications.

How is motor braking energy processed in Bosch Rexroth Indramat DKR04.1-W400E-BE32-01-FW with rigid DC bus structure?

The braking energy is redirected into external resistor networks through the brake chopper, maintaining DC bus stability during rapid deceleration phases.
