The Rexroth Indramat R911274164 (DKR03.1-W100Z-BE43-02-FW) is an industrial drive controller engineered for precise control of motors, including 2AD, ADF main spindle motors, 1MB frameless spindle motors, and linear motors. It supports a system frequency of 50-60 Hz and requires an AC 230 V control voltage (±10% tolerance). This controller incorporates digital servo and resolver feedback, utilizes a SERCOS command interface for real-time communication, and features an integrated blower for air cooling with a heat dissipation capacity of 900 W. The device is equipped with an ESM02.3 software module, a SERCOS interface command card, and is configurable via plug-in modules. It supports a rated current of 100 A, operates up to +45 °C, and conforms to IP20 protection standards.

Frequently Asked Questions

What diagnostic protocols does the Bosch Rexroth Indramat DKR03.1-W100Z-BE43-02-FW drive utilize for detecting thermal drift during prolonged aerospace drive operation?

The drive employs internal thermal mapping sensors with air-cooling diagnostics, interfaced via SERCOS channels, enabling consistent reporting and controlled shutdowns without destabilizing the motor feedback loop.

Does the Bosch Rexroth Indramat DKR03.1-W100Z-BE43-02-FW drive support internal bleeder circuit redundancy for safe aircraft testing environments?

Yes, its integrated bleeder circuitry manages excess DC-link energy, maintaining system voltage equilibrium and extending motor drive electronics reliability during shutdown or emergency deceleration phases.

What grounding configurations are required for Bosch Rexroth Indramat DKR03.1-W100Z-BE43-02-FW drive to prevent electromagnetic interference during motor control cycles?

The drive mandates shielded cable routing with star-point grounding, reducing parasitic oscillations and safeguarding motor resolver signals from distortion in aerospace-grade testing systems.

What protections does Bosch Rexroth Indramat DKR03.1-W100Z-BE43-02-FW drive integrate against DC-link overvoltage during abrupt motor decoupling?

The drive incorporates an active bleeder and crowbar circuitry, dispersing transient surges and protecting motor feedback electronics during unexpected load disconnections.

Does Bosch Rexroth Indramat DKR03.1-W100Z-BE43-02-FW drive feature firmware interlocks that mitigate motion hazards during aerospace drive integration?

Yes, firmware-defined interlocks govern permissible motion modes, instantly restricting unsafe drive commands to preserve operator and system safety during test-cell motor routines.
