Product Overview
The Rexroth DKC22.3-016-7-FW is an ECODRIVE 03 servo drive controller intended for coordinated motor control in industrial machinery. The complete designation identifies a DKC22.3 controller in the 016 current class, with the 7 DC-bus voltage class and firmware-dependent functionality.
This drive is primarily relevant to maintenance, machine restoration and exact replacement projects involving established Rexroth Indramat ECODRIVE 03 systems. Selection must be based on the complete type code and the identification information on the installed unit. A generic DKC controller or another DKC22.3 current class should not be treated as a direct substitute without a full compatibility review.
Main Features
- ECODRIVE 03 servo drive controller for industrial motion applications.
- DKC22.3 hardware and control-interface version.
- 016 type-current class for comparatively lower-current servo-axis requirements.
- Designed for connection to a compatible Rexroth servo motor, motor feedback system and machine control architecture.
- Supports motor power, motor temperature monitoring and holding-brake connections according to the applicable system configuration.
- Firmware-dependent drive functions and parameter handling.
- Suitable for exact-code maintenance replacement in compatible ECODRIVE 03 installations.

System Configuration and Applications
The DKC22.3-016-7-FW can be used in machine-tool axes, packaging machinery, printing equipment, handling systems and other automated machines originally engineered around ECODRIVE 03 technology. Actual motor capacity, output-current availability and operating performance depend on the motor, switching frequency, mains arrangement, ambient conditions and drive parameterization.
The controller must be matched with the correct motor power cable, feedback cable, motor feedback type, holding-brake circuit and control interface. The machine electrical diagram and the original drive documentation should be treated as the primary replacement references.
Replacement Checklist
- Confirm the complete model: DKC22.3-016-7-FW.
- Verify the R911 material number directly from the original nameplate.
- Check the complete FWA firmware code and firmware release.
- Confirm the programming or parameter module used by the machine.
- Verify the motor model, feedback system and feedback cable.
- Check the motor power cable, brake wiring and temperature-monitoring circuit.
- Confirm the command interface and machine communication arrangement.
- Back up the existing parameters before removing the installed controller.
- Review the controller project and machine-specific commissioning data.
Compatibility notice: DKC22.3-040-7-FW, DKC22.3-100-7-FW and DKC22.3-200-7-FW are related current-class versions, but they are not automatically interchangeable with DKC22.3-016-7-FW. Mechanical dimensions, wiring, mains components, motor matching and project parameters must be reviewed before replacement.
Related Models
Related ECODRIVE 03 controller models include DKC22.3-040-7-FW, DKC22.3-100-7-FW and DKC22.3-200-7-FW. The appropriate version must be selected from the original machine documentation rather than current class alone.
Inquiry and Supply Notes
For an accurate identification check, provide the complete drive nameplate, R911 material number, FWA firmware designation, motor model, feedback configuration and photographs of the installed connections. Availability, condition, firmware scope and compatibility should be confirmed for each inquiry.
