AKD-N Decentralized Servo Drive System

Feb. 13, 2014
Kollmorgen's servo drive system reduces cabinet space with 80% less cabling.

AKD-N is a distributed servo drive solution that reduces cabinet space and cabling hassle, simplifying machine design, set up, and operation. This drive system leverages IP67-rated drives positioned next to the motor and supplied by a central power module located in the switchgear cabinet. A 0.4-in. (11 mm) diameter hybrid cable delivers power and Fieldbus communication to the AKD-N servo drives. As a result, the drives operate directly in series, supplying up to 4 kW per axis. 


Safe Torque Off functionality is integrated into the system and can be deactivated on an individual or collective basis. This enables machine builders to achieve safety requirements without adding additional contactors to the panel.

  • 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
