Microstepping Drive with L20 Perspective

Compumotor’s ZETA4 drive is a stand-alone, packaged microstepping drive incorporating breakthrough technologies. The ZETA’s Electronic Viscosity (patent pending) complements the L20 linear step motor. The result is slow-speed smoothness and reduced end-of-move settling time.



  • Standard step-and-direction input or CW (up)/CCW (down) input
  • Force from 20 lb (89 N)
  • Electronic Viscosity (patent pending) benefits: – Reduce settling time – Increase slow-speed smoothness (reduce velocity ripple) – Reduce audible noise
Protection Circuit
  • Motor short circuits (phase-to-phase and phase-to-ground)
  • Overtemperature
  • Undervoltage
  • Power dump (dissipates excess voltage caused by load regeneration)
  • Drive status indicators: power, step input, under voltage, over voltage and motor fault
  • 120VAC (170VDC bus voltage)
  • Removable connectors for easy installation
  • Selectable Electronic Viscosity damping for optimized performance
