E1701M 4-Axis Motion Controller

Please note: we're supporting the global strike for climate on 20. 09. 2019 and close down the whole company for 24 hours.
So there will be no support and no shipping at this day.

Beside some other motors and controller cards BeamConstruct supports
the E1701M™ stepper motor controller board. This is a Ethernet
and USB controllable card which provides following features:

  • 100 Mbit Ethernet connection
  • USB 2.0 connection
  • Command execution time down to 1 microsecond
  • Support of up to four independent motion axes
  • Generates step and direction pulses for usage with stepper motor driver
  • 500 kHz maximum step clock
  • Linear, exponential and s-shaped acceleration modes
  • Freely definable referencing modes with auto-searching for reference switch
  • Realtime processing
  • Programmable via binary API (via DLL/Windows or .so/Linux) or ASCII command
    interface (via Telnet/Ethernet or serial interface/USB)
  • 512 MByte DDR3 RAM
  • 1 GHz CPU clock
  • Extremely low power consumption of 1,9 W (non-insulated mode)
  • 8 digital outputs providing either CMOS logical levels or electrically insulated outputs via external power supply for controlling 4 motors via step and direction signals
  • 8 freely usable digital inputs expecting either CMOS logical levels or electrically insulated inputs via external power supply for usage with limit-/reference switches or
    encoder inputs
  • Two decoders for evaluation of axis position via quadrature encoder signal
  • alternative operation mode: jog-control (manual/stand-alone), signals at inputs start movement of related axes
  • alternative operation mode: I/O controller card with 8 independent digital outputs and 8 digital inputs
  • Very small size of about 87 mm x 55 mm
  • Hardware/firmware is quality made in EU/Germany
