The Bosch Rexroth MPN R911325565 (DKR03.1-W200N-BA37-01-FW) is an industrial drive controller from the DKR product series, supporting servo and resolver motor feedback. It operates on 3-phase AC power at 400–480 V, delivering continuous output of 30 kW or 35 kW at 92 A and 78 A, for 4 kHz and 8 kHz drive frequencies respectively. The unit has a rated current of 200 A and incorporates a built-in blower for air cooling, dissipating up to 800 W of heat. It is designed to meet IP20 protection, operates effectively up to 1000 meters altitude, and uses an analog command interface with an ESM02.3 firmware module. The configuration does not include a bleeder or brake chopper, features a rigid DC bus, and the total weight is approximately 49 kg, including 1.7 kg of accessories. The operating temperature range is 0 to +45°C.

Frequently Asked Questions

Where are current measurement shunts positioned within the Bosch Rexroth Indramat DKR03.1-W200N-BA37-01-FW drive structure?

The shunts are embedded within the inverter bridge leg channels, offering instantaneous sampling for each phase current to guarantee symmetry and overload detection.

What role does the blower system play in Bosch Rexroth Indramat DKR03.1-W200N-BA37-01-FW drive for air cooling?

The integrated blower maintains uniform thermal distribution, avoiding localized hotspots, while ensuring compact internal convection paths for consistent operation.

How does Bosch Rexroth Indramat DKR03.1-W200N-BA37-01-FW drive regulate bleeder-less energy dissipation during deceleration?

It routes regenerative energy into controlled DC bus balancing sequences, preventing overvoltage conditions by phase-adjusted modulation.

Does Bosch Rexroth Indramat DKR03.1-W200N-BA37-01-FW drive provide filtering for command ripple in analog interface?

Yes, ripple suppression is applied via adaptive filtering blocks, stabilizing signal transitions to avoid erratic torque surges under load changes.

What environmental derating curves apply to Bosch Rexroth Indramat DKR03.1-W200N-BA37-01-FW drive?

The drive derates proportionally beyond 40°C ambient, scaling maximum current output downward to sustain longevity of power semiconductor assemblies.
