AKD2G Servo Drive

AKD2G Servo Drive >

Born from a rich AKD heritage, AKD2G is the latest servo drive technology adding:

  • Dual-axis technology for additional space savings
  • Built-in functional safety options via SafeMotion Monitor (including FSoE)
  • Color Graphic Display
  • Optimized for single-cable power and feedback

AKD Servo Drive >

AKD® Series is a proven perfomer, supporting the largest customer installed base, and offers:

  • Industry leading motion control loops
  • Extensive motor feedback and drive fieldbus support including EtherCAT, EtherNet/IP, Profinet RT, etc.
  • Plug-and-play with Kollmorgen motors
  • WorkBench GUI, acclaimed for customer experience and usability

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


AKD BASIC drives provide all the performance features of our leading AKD Series, along with built-in machine and motion control that can be programmed in BASIC programming language from AKD WorkBench. These drives can eliminate the need for a separate PLC or allow machine designers to customize drive functionality.

ADK PDMM® - Servo Drives - Kollmorgen


The AKD PDMM® combines one AKD servo axis and the PCMM EtherCAT master controller that supports up to 31+ more additional AKD axes.

  • Full KAS automation capabilities using IEC61131-3 soft PLC industry standard programming language
  • Integrated control for multiple servo axes, complete I/O and HMI interface
