Product Overview
The DKC10.3-018-3-MGP-01VRS is a Bosch Rexroth Indramat DKC Series servo drive controller from the EcoDrive Cs family. It is designed for AC servo motor control in single-axis and multi-axis industrial motion applications. The unit uses a 300 V nominal DC bus and provides an 18 A rated current, making it suitable for demanding machine-tool, material-handling, packaging, and automated production equipment. Its MGP-01VRS firmware is configured as a standard multi-interface, general-purpose firmware package. The controller supports cabinet installation and can be expanded with compatible interface cards for application-specific communication requirements. The device is identified with Rexroth part number R911295612, providing an additional reference for procurement and spare-parts verification.

Key Features and Benefits — DKC10.3-018-3-MGP-01VRS
- 18 A rated current for industrial servo applications.
- 300 VDC nominal DC-bus architecture.
- Multi-interface, general-purpose firmware.
- Suitable for single-axis and multi-axis machine systems.
- Supports application expansion through compatible interface cards.
- Compact cabinet-mounted design.
- Compatible with Bosch Rexroth Indramat EcoDrive Cs servo systems.
- Useful for maintaining legacy motion-control installations where an exact drive replacement is required.
The important procurement detail is the complete drive code. Current rating alone is not enough to identify a compatible replacement because firmware, design version, communication interface, and motor configuration can affect system compatibility.

Installation and Maintenance — DKC10.3-018-3-MGP-01VRS
Before installation, verify the motor type, drive parameters, DC-bus arrangement, interface card, firmware, encoder connection, and cabinet cooling conditions. The controller is intended for cabinet mounting and should be installed with adequate heat dissipation.
During maintenance, inspect power terminals, motor connections, feedback wiring, communication interfaces, and cooling paths. Record the existing parameter set before replacing the controller whenever possible. After installation, verify motor feedback, axis direction, acceleration limits, fault history, and application parameters before returning the machine to production.
Personally, I would compare the complete type code and stored drive parameters before approving a replacement. A visually identical DKC unit can still have a different firmware or interface configuration.
Product Warranty — DKC10.3-018-3-MGP-01VRS
Warranty coverage should be confirmed with the supplier according to the actual supplied condition, such as new surplus, refurbished, repaired, or tested-used. For critical motion-control spares, procurement records should include the complete type code, serial number, firmware information, inspection status, and applicable warranty period.
When sourcing the Rexroth DKC10.3-018-3-MGP-01VRS, verify the motor, feedback system, communication configuration, and existing drive parameters before purchase.
