Servostar 300 Servo Drive

Kollmorgen’s Servostar 300 Series digital brushless servo drives are compact, easy-to-use and extremely versatile. The small footprint saves space in the switchgear cabinet, and with its wide-ranging connectivity options the S300 may be the only drive family you need. These drives work with our best-in-class rotary servomotors and linear positioners to provide a single, high-performance solution for a wide variety of applications.


  • CE, UL, cUL
  • Operation directly from grounded 115 to 480 VAC, 3-phase, 50-60 Hz lines
  • Output current: 1.5 to 10 Amps RMS/phase, continuous
  • With integral AC line filter, all shield connections terminate directly to the amplifier
  • DC-link circuits can be connected in parallel
  • Fully programmable via RS232 interface
  • Easy setup using a Windows-based graphical interface
  • 230 V type suitable for 200 mm switchgear cabinets
  • Interface integrated for stepper controllers, master-slave operation and electronic gearing
  • Integrated position controller with memory for 300 intelligent positioning tasks, including Speed profile, Register control, Jolt limiting, Daisy-chained tasks, Absolute and relative tasks and Several types of reference traverses
  • Motion Control and Soft-PLC integrated
  • Encoder emulation: choose incremental (A quad B, dec./bin.) or absolute (SSI, Gray/bin.)
  • Compatible with a wide range of feedback options including Resolver (up to 36 poles), ComCoder, Incremental or sine encoder with Hall sensor, Sine encoder with EnDat/HIPERFACE/BISS, Sine encoder without data and Incremental encoder A quad B


  • Wide power range allows a single drive family to be deployed throughout the entire machine
  • Compact footprint requires less cabinet space and allows mounting close to the point of use
  • High performance system designed for increased machine throughput
  • Easy-to-use graphical user interface reduces engineering and support time
  • Reduced overall cost
