Product Introduction
The Kollmorgen AKD-N00307-DSEC-E000 is designed for decentralized motion-control installations where servo amplifiers are mounted close to their motors rather than inside a central electrical cabinet. It receives DC power and EtherCAT communication through a hybrid connection from a compatible central supply or upstream drive. This architecture reduces cabinet space and simplifies motor-side wiring.
The DS configuration provides a local STO input, allowing the drive’s power stage to be disabled through an external safety circuit. The drive also supports multiple motor feedback technologies, but the exact feedback interface and the meaning of the E000 configuration suffix should be verified against the nameplate and Kollmorgen ordering documentation.

Application Scenarios & Field Pitfalls
Typical applications
- Packaging machinery: Controls distributed servo axes on filling, sealing, labeling, and material-handling machines.
- Food and beverage production: Supports motor control near machine sections where reduced cabinet wiring and suitable enclosure protection are required.
- Automated production lines: Coordinates multiple decentralized axes through EtherCAT and a shared DC power distribution system.
- Machine safety integration: Uses local STO inputs as part of an appropriately designed external safety circuit.
Field checks before replacement
- Confirm the complete type code. Verify
AKD-N00307-DSEC-E000against the side nameplate. Do not assume that another AKD-N00307 with a different DS, DF, or DB configuration is interchangeable. - Check DC-bus compatibility. The documented rated supply is 560–680 VDC. The drive is not a conventional 230 VAC or 400 VAC cabinet-mounted servo amplifier.
- Verify thermal mounting. The 3 A continuous rating requires the specified cold plate. Without it, the documented free-convection rating is only 1.8 A.
- Check STO wiring. The DS version has a dedicated local STO connection. Verify the external safety relay or safety controller, input polarity, wiring, and functional test procedure. STO does not replace electrical isolation or mechanical braking.
- Match motor feedback. Confirm whether the motor uses SFD, EnDat, BiSS, Comcoder, Hiperface, or another supported feedback system. The exact feedback configuration must match the drive.
- Use the correct hybrid cables. The hybrid connection carries DC power and communication signals. Confirm cable type, connector coding, length, and condition before commissioning.
- Check EtherCAT topology. Verify the master configuration, node sequence, addressing, and drive firmware. A physical network connection alone does not establish correct motion communication.
- Test safety after replacement. Kollmorgen requires an STO functional test after initial startup and after wiring changes or component replacement.

Procurement and Replacement Notes
Before purchasing, request photographs of the complete nameplate, connector panel, X6 safety connection, and motor-feedback interface. Confirm whether the unit is supplied with its mounting hardware, mating connectors, and required cables; Kollmorgen lists several of these accessories as separately ordered items.
Recommended inspection checklist:
- Exact part number: -DSEC-E000
- Hardware revision and serial number
- 3 A continuous / 9 A peak current configuration
- Local STO option and safety-interface condition
- Motor feedback compatibility
- EtherCAT communication test
- Hybrid power-cable compatibility
- Cold-plate mounting arrangement
- Drive fault history and functional-test documentation
Replacement warning: A standard is not automatically equivalent to the DS-equipped version. Confirm the local STO function, motor feedback configuration, and complete ordering code before approving a replacement.
