AKD-N Decentralized Servo Drive

The AKD-N decentralized servo drive reduces cabinet space and opens the way to a smarter machine automation with 80% less cabling. Typical applications for the AKD-N are packaging machines and production machines in food and beverage industry.

  • IP67 drives can be mounted to machine, outside the control panel
  • Reduced cabling because DC, network, power supply, I/O level as well as safety (STO) run in one cable
  • More flexibility in machine design, can be “cold plate” mounted

Lay Less Cable

Imagine your machine includes eight axes each with a distance of three meters. The switch cabinet is 5 meters away and on each axis there is also a switch. In this example that equates to a total of 372 meters of cable with typical servo drives, but with AKD-N it is only 42 meters. The decentralized servo technology of the AKD-N saves 330 meters here.

AKD-N Decentralized Drive Cabling

  1. 1Hybrid cable AKD-C to AKD-N: CCNCN1
  2. 2Hybrid motor cables for single-cable operation:
    • CCJNA2
  3. 3Hybrid cable AKD-N to AKD-N:
    • CCNNN1
  4. 4Motor cables for dual-cable operation:
    • CMØNA2 without brakes
    • CM1NA2 with brakes
  5. 5Feedback cables for dual-cable operation:
    • CFSNA2 SFD
    • CFCNA2 Comcoder
    • CFENA2 EndDat / BiSS
    • CFHNA2 Hiperface



Reduce costs

  • Reduced cabling because DC and network, power supply, I/O level as well as safety (STO) run in one cable
  • Fast and simple assembly, even without special knowledge, through ready-made and tested cables
  • Lack of derating enables smaller motor and servo drive combinations compared to integrated system with the same output power

Compact machines

  • Smaller and therefore easily integrated switch cabinets
  • Servo drives in the immediate vicinity of the motor
  • Robust construction in Protection class IP67 makes protective enclosures superfluous

Faster startup

  • Plug connectors in IP67 for connection without tools
  • At only eleven millimeters, the thin hybrid cable can be laid in a space-saving manner – even in tight machine corners, thanks to a small bending radius
  • Simple connection of I/O systems or networks directly to the drive
  • Parameterization with Kollmorgen's WorkBench software

Higher machine effectiveness (OEE)

  • Design supports fast and effective cleaning
  • High operating safety through robust construction
  • Precision through digital feedback
  • Everything at a glance: Status display on servo drive

More flexibility in machine design

  • Compatible with all motors from Kollmorgen with single-cable, or dual-cable, connection
  • Simple combination of central and decentralized controllers within the comprehensive AKD family
  • Faster modification and upgrade options through linear topology as well as I/O and network interfaces at the axis
