The R911307397 (DKR04.1-W400N-BT01-01-FW) is a Bosch Rexroth DKR Series drive controller designed for motor operation with output power from 10 kW to 93 kW and a rated current of 400 A. It supports expandability through optional external brake resistor and additional command interface cards, with a SERCOS interface for communication. The unit features an integrated main contactor, emergency stop shutdown device, and accepts both digital servo and resolver feedback. Cooling is achieved via a built-in blower, and the device should be installed in an enclosed cabinet with a minimum clearance of 160 mm for proper air circulation. It is specified for operation up to 55°C with corresponding load factor adjustments, weighs approximately 150 kg, and is supplied with a mechanical accessory kit. The firmware must be ordered separately.

Frequently Asked Questions

Where is resolver feedback utilized in the Bosch Rexroth Indramat DKR04.1-W400N-BT01-01-FW motor system?

Resolver feedback in the DKR04.1-W400N-BT01-01-FW ensures robust motor positioning by delivering analog sinusoidal signals, improving synchronization under mechanical vibrations and high-temperature industrial conditions.

Does the Bosch Rexroth Indramat DKR04.1-W400N-BT01-01-FW motor require external cooling equipment?

No, the DKR04.1-W400N-BT01-01-FW employs a built-in air blower unit. This integrated cooling mechanism eliminates external chillers while providing steady airflow over critical drive electronics.

What rated current limit does the Bosch Rexroth Indramat DKR04.1-W400N-BT01-01-FW motor drive sustain?

The DKR04.1-W400N-BT01-01-FW maintains a 400A rated current. This continuous amperage capacity supports high-torque servo motors without current derating under extended industrial workloads.

Where does digital servo feedback enhance motion accuracy in the Bosch Rexroth Indramat DKR04.1-W400N-BT01-01-FW motor?

Digital servo feedback captures precise encoder signals, boosting accuracy in interpolated motor movements. It reduces drift in multi-axis machining centers and robotic arm assemblies.

What command resolution is achieved through SERCOS in Bosch Rexroth Indramat DKR04.1-W400N-BT01-01-FW motor?

The SERCOS achieves high-resolution command transfer with microsecond synchronization cycles. This allows motor axis control accuracy within microns, suitable for fine-tolerance machining.
