DCM8027 & DCM8054

Haydon Kerk Stepper Motor Drive DCM8027-DCM8054
The Haydon Kerk DCM8054/8027 is a fully digital stepper drive developed with advanced DSP control algorithm based on the latest motion control technology. It has achieved a unique level of system smoothness, providing optimal torque and nulls mid‐range instability. Compared with traditional analog drives, DCM8054/8027 can drive a stepper motor at much lower noise, lower heating, and smoother movement. Its unique features make DCM8054/8027 an ideal choice for high performance applications.

Features :
  • User friendly chopper drive
  • Anti‐resonance provides optimal torque and nulls mid‐range instability
  • Soft‐start with no “jump” when powered on
  • 14 selectable resolutions in decimal and binary
  • TTL compatible and optically isolated input
  • Automatic idle‐current reduction
  • Up to 80VDC input voltage (for Europe 70 VDC max.)
  • Requires external pulse generator
