Kollmorgen Support Network


The Decentralized Drive System consists of an AKD-C and AKD-N drives, which are mounted to the machine close to the motor. A single cable connection is realized between AKD-C and AKD-N, as well as between AKD-N and AKD-N, using Kollmorgen hybrid cables. The drives are supported by the smart AKD-C Power Supply with DC power.

  • Nominal supply voltage range 560 VDC to 680 VDC (max. 800V); Standby supply voltage 55 VDC
  • 3A, 6A, and 12A output current
  • MultiFeedback (SFD, SFD3, Hiperface DSL, Comcoder, ENDAT 2.1 & 2.2, BiSS, HIPERFACE, 1Vp-p SinCos encoders, incremental encoders)
