The R911296034 (DKR03.1-W100N-BA31-01-FW) is a Rexroth Indramat drive controller from the DKR series, featuring a rated current of 100 A and support for digital servo and resolver feedback. It utilizes an integrated brake resistor capable of handling up to 150 kWs maximum braking energy, with 40 kW peak and 1 kW continuous braking power. The unit has an internal air cooling system with a built-in blower and operates at a control voltage of 230 V AC (50–60 Hz), with a power rating of 200 VA at 100% nominal data. Maximum heat dissipation at Iconteff is 900 W, and it is rated for operation up to +55 °C ambient (with 80% derated nominal data). The controller is classified as IP20, uses an analog interface for command input, does not include a bleeder, and conforms to design version 1 and function numeric version 01. Electrical connections must follow the provided circuit diagrams to ensure proper operation.

Frequently Asked Questions

What signal grounding methodology is advised for DKR03.1-W100N-BA31-01-FW motor analog inputs?

Star-grounding with shield terminations at a single point is recommended. This reduces interference, ensuring clean analog signals for motor drive accuracy.

Does the Bosch Rexroth Indramat DKR03.1-W100N-BA31-01-FW motor control tolerate fluctuating load inertia variations?

It tolerates moderate inertia shifts using dynamic compensation. Stable torque is achieved, but excessive mismatches require tuning or mechanical adjustments.

How does Bosch Rexroth Indramat ensure the DKR03.1-W100N-BA31-01-FW motor servo remains stable during analog offset drift?

Offset drift is minimized using calibration routines and input filtering. These stabilize the motor command voltage, preventing unwanted drift in torque output.

Where do thermal derating curves apply for DKR03.1-W100N-BA31-01-FW motor duty cycles?

They apply when ambient temperature exceeds standard conditions. Motor currents must be reduced proportionally, preventing overheating in extended operational duty cycles.

How does Bosch Rexroth Indramat synchronize DKR03.1-W100N-BA31-01-FW motor responses with multi-axis automation?

Synchronization is managed via feedback loops and analog coordination. Each motor axis aligns with precise timing, supporting accurate multi-axis motion tasks.
