The DC2M17 form-factor allows easy mounting to a NEMA17 step motor, and optional DC2M17-CASE gives added heat dissipation and physical protection. A wiring harness with color-coded connections is also available. Features:

  • Programmable max phase current, up to 2A max (per phase) with optional heatsink/case (1.5A without case)
  • Single input supply voltage from 8 to 35VDC
  • Built-in fuse protection for added safety
  • Programmable step resolutions: Full, 1/2, 1/4, 1/8, 1/16 step
  • Drive step rates from 1/255th to 28,000 steps/second
  • Four configurable input ports; generic or fixed-function
    • Fixed functions include Home, Go, Stop, Limits and Jogs
  • Two general purpose output ports can drive 1A loads
  • All I/O can be referenced to external voltage from 5-30V
  • AM Comms Control bus utilizes RS-485 (TIA-485)
  • Status LED indicates stepping status and power on
  • Programs and Parameters can be stored in non-volatile internal memory, and a stored program can auto-run at start-up
  • Easy Command Line Interface, with over 38 motion commands and settings
