The Bosch Rexroth Indramat R911283127 (DKR03.1-W200N-BA04-01-FW) is an AC drive module from the DKR series, designed for industrial servo applications. This unit supports a rated current of 200 A and operates without a bleeder or brake chopper, utilizing a rigid DC bus. It features an analog command interface and supports both digital servo and resolver feedback. Cooling is managed by an integrated air blower. The drive incorporates a thyristor bridge with a phase voltage capability up to 520 V, and connections can be made directly to ground or via an external three-phase system. Adjustment for differing input voltages is accomplished with an autotransformer, and isolation from voltage disturbances is provided by an isolating transformer. Communication is enabled via a serial interface, with parametrization handled through compatible software such as SERCTOP or DriveTop. This model corresponds to design version 1 and function numeric version 01 in line series 03 of the DKR product series.

Frequently Asked Questions

How does the absence of a brake chopper affect installation of the DKR03.1-W200N-BA04-01-FW?

Without a brake chopper, external braking modules may be required in high-inertia applications. This simplifies the DC bus but shifts braking energy handling outside the drive.

What are the advantages of air cooling with a built-in blower?

It reduces the need for external cooling infrastructure and simplifies integration. However, airflow clearance and dust filtration must be ensured in the cabinet design.

How does analog command input influence system flexibility?

Analog control allows compatibility with older or mixed-control environments. It also enables direct interfacing with PLCs or controllers outputting continuous voltage signals.

Can digital servo and resolver feedback be used simultaneously?

Yes, this dual feedback capability increases control accuracy. It also provides redundancy if one feedback element experiences signal degradation.

How does the DKR03.1-W200N-BA04-01-FW handle high-current loads?

At 200 A rated current, it supports large servo motors with significant torque demands. This makes it suitable for heavy-duty automation and high-power axis drives.
