Bosch Rexroth R911295612 | DKC10.3-018-3-MGP-01VRS Drive Controller

Description

Product Introduction

The Bosch Rexroth DKC10.3-018-3-MGP-01VRS is an ECODRIVE Cs DKC-series servo drive controller designed for industrial AC servo applications. Its designation identifies a Series 10 controller, Version 3, with an 18 A rated current and a 300 VDC nominal DC bus. The MGP-01VRS firmware designation refers to the multi-interface, general-purpose firmware configuration.

The controller is intended for machinery requiring controlled servo motion rather than simple motor starting. It can be used in single-axis and multi-axis machine architectures, with application-specific communication and motor configurations. Optional interface cards can affect how the controller integrates with the machine control system, so the complete hardware configuration should be checked before treating another DKC unit as a replacement.

For procurement, R911295612 is an important cross-reference. Some listings identify the controller by its type code while others use the numeric reference, so both should be included on a purchase request.

Key Technical Specifications

*These values appear in secondary technical listings and should be verified against the exact hardware revision and applicable Rexroth documentation before being used for engineering calculations.

A separate equipment listing identifies a Master Communication Card configuration as ECM01.1-DN01 and gives the associated card reference as R911295614. This is useful when comparing an installed controller with a replacement, because the controller’s communication hardware can be configuration-dependent.

Application Scenarios & Engineering Considerations

The DKC10.3 belongs to a generation of Rexroth servo controllers commonly encountered in established machine-tool and production equipment. Its value in a maintenance context is less about adding new functionality and more about preserving an existing servo architecture without changing the machine’s motor/control interface.

• Machine-tool axes: Suitable for servo-controlled positioning where speed and torque regulation are handled by the drive.
• Material-handling machinery: Can be used in coordinated servo applications such as conveyors, indexing mechanisms, and positioning systems.
• Packaging equipment: Servo drives of this class are appropriate for synchronized motion where repeatable acceleration and positioning are required.
• Multi-axis machinery: DKC controllers can be incorporated into systems containing multiple servo axes, with the actual architecture determined by the machine controller and communication configuration.

Field note: A DKC drive that trips during acceleration should not automatically be replaced. Motor feedback, motor cable insulation, DC-bus condition, mechanical loading, braking components, and parameterization can all produce drive faults that appear to originate from the controller.

The Engineer’s Guide: Field Pitfalls to Avoid

⚠️ Do not replace it using the 18 A rating alone.

A DKC controller’s motor compatibility depends on the motor, feedback system, parameters, firmware, and communication configuration.

How to avoid it: Match the complete type code:

DKC10.3-018-3-MGP-01VRS

and the reference:

R911295612

before approving a substitute.

⚠️ Verify the communication card.

The DKC can be equipped with additional interface hardware. One documented configuration lists ECM01.1-DN01 as the master communication card.

How to avoid it: Photograph and record the communication-card designation on the existing unit before ordering a replacement.

⚠️ Preserve the drive parameters.

Replacing the hardware without recovering the existing parameter set can turn a straightforward component replacement into a machine commissioning exercise.

How to avoid it: Back up drive parameters and record motor type, feedback configuration, acceleration/deceleration settings, current limits, and communication parameters before removing the original controller.

⚠️ Check the motor before blaming the drive.

Overcurrent, following-error, encoder, and DC-bus faults can originate outside the DKC itself.

How to avoid it: Check motor insulation, feedback wiring, mechanical load, brake operation, and cabinet DC-bus conditions as part of the fault investigation.
