Product Overview
The Rexroth DKC22.3-200-7-FW is a high-current-class servo drive controller from the ECODRIVE 03 platform. It is intended for industrial motion systems requiring a DKC22.3 controller in the 200 type-current class and the 7 DC-bus voltage class.
This controller is mainly used for maintenance and replacement of established Rexroth Indramat drive systems. Because the 200-class unit has different installation and power-system requirements from the smaller DKC22.3 versions, replacement selection must cover the complete drive designation, surrounding mains components, cabinet arrangement, cooling conditions, motor combination and firmware.
Main Features
- ECODRIVE 03 servo drive controller for demanding industrial motion systems.
- DKC22.3 controller and interface version.
- 200 type-current class for higher-current drive applications.
- Designed for operation with a compatible Rexroth motor, feedback system and machine controller.
- Provides drive-side connections for motor power, temperature monitoring and holding-brake control according to the system design.
- Firmware and parameter configuration must correspond to the installed machine project.
- Suitable for exact replacement, machine restoration and legacy automation maintenance.

System Configuration and Applications
The DKC22.3-200-7-FW may be found in larger machine-tool axes, printing systems, packaging and converting machinery, material-handling equipment and production machines requiring a higher-current ECODRIVE 03 controller. Its usable output and motor compatibility cannot be determined from the 200 code alone.
Engineering checks should include the selected motor, required torque-speed profile, switching frequency, mains connection, external mains components, braking arrangement, cabinet ventilation and ambient temperature. The DKC22.3-200 installation layout and terminal arrangement must be checked against the machine electrical documentation.
Installation and Compatibility Notes
- Confirm that the cabinet provides the required mounting space and cooling airflow.
- Verify the approved mains connection and required protective components.
- Check the motor power cable size, terminal arrangement and protective conductor connection.
- Confirm the motor feedback interface and feedback cable.
- Verify motor temperature monitoring and holding-brake wiring.
- Check the machine control interface and controller-project configuration.
- Confirm the complete firmware and parameter-module arrangement before commissioning.
Replacement Checklist
- Confirm the complete model: DKC22.3-200-7-FW.
- Verify the R911 material number from the original nameplate.
- Record the complete FWA firmware designation and firmware release.
- Back up all drive parameters and machine-specific commissioning data.
- Confirm the programming module or parameter module configuration.
- Check the motor model, motor feedback and cable set.
- Verify mains components, fuses, contactors, filters and line reactors against the machine design.
- Check braking components and DC-bus connections where applicable.
- Confirm cabinet dimensions, ventilation and terminal accessibility.
Replacement warning:
Do not replace this controller using only the DKC22.3 family designation. DKC22.3-016-7-FW, DKC22.3-040-7-FW and DKC22.3-100-7-FW belong to the same family but represent different current classes and may have different dimensions, terminal arrangements and external-component requirements.
Related Models
Related ECODRIVE 03 models include DKC22.3-016-7-FW, DKC22.3-040-7-FW and DKC22.3-100-7-FW. These models should be presented as related products rather than direct substitutes unless the complete drive-system engineering has been reviewed.
Inquiry and Supply Notes
For model verification, provide photographs of the complete nameplate, R911 material number, FWA firmware code, motor model, feedback type, parameter-module information and terminal layout. Availability, physical condition, included firmware and system compatibility should be confirmed separately for each requirement.
