The R911313991 (DKR04.1-W400N-BE45-01-FW) is a Rexroth Indramat DKR series digital drive controller designed for the control of various Rexroth Indramat motors, including LSF or LAF linear motors and selected spindle motors. It is engineered for applications requiring high precision and a wide speed range at constant power, providing an output shaft power from 10 kW to 93 kW and a rated current of 400 A. The controller supports digital servo and resolver feedback, employs air cooling via a built-in blower, and interfaces with higher-level control systems through the SERCOS interface. The device features a rigid DC bus without an integrated bleeder or brake chopper. Compatible motor and drive configurations are specified in Rexroth documentation.

Frequently Asked Questions

How does Bosch Rexroth Indramat DKR04.1-W400N-BE45-01-FW motor controller handle resolver signal degradation over maximum 75m feedback cable length?

It deploys compensation circuits that stabilize resolver waveforms and digital signal integrity, ensuring precise angular measurement. Shielding and impedance-matched lines mitigate interference along the extended feedback transmission.

Where is the optimal grounding point when Bosch Rexroth Indramat DKR04.1-W400N-BE45-01-FW motor controller is coupled with linear motor cabling?

Grounding must occur at the drive’s protective earth terminal to minimize loop currents. Distributed earthing is avoided to reduce magnetic noise that distorts linear motor position feedback.

What type of thermal monitoring strategy does Bosch Rexroth Indramat DKR04.1-W400N-BE45-01-FW motor system apply in spindle integration?

It utilizes embedded thermal sensors linked to the drive controller that continuously evaluate coil and bearing heat. Data informs automatic torque derating to prevent catastrophic spindle overheating.

Does Bosch Rexroth Indramat DKR04.1-W400N-BE45-01-FW motor controller support direct fiber optic redundancy for SERCOS networking?

Yes, it allows dual fiber channels for fault tolerance. In case of primary optical line interruption, automatic switchover maintains uninterrupted deterministic motor communication cycles.

How is resonance suppression performed in Bosch Rexroth Indramat DKR04.1-W400N-BE45-01-FW motor loops for NC tools?

It uses adaptive notch filters dynamically tuned to vibration frequencies. This minimizes resonance amplification, keeping axis precision intact under cutting load or rapid traverse conditions.
