Axis Controller

Axis is a single-axis jog controller for motors driven by a step/dir interface.

Features

  • Power: Wide power supply input support from 9 to 24 VDC

  • Interface:

    • STEP, DIR, EN 5V logic
    • LIM+/LIM/GND limit input with with configurable edge trigger
    • FAULT input
    • Configurable pin directions (Step, Dir, Enable, Limit)

  • Limits: Support for mechanical, PNP or NPN terminal switches

  • Homing: The limit switch can used as a home switch, a reference poin where the position is zeroed out and motion is then restricted within the bounds of software (virtual) limits.
  • Speed potentiometer, Jog buttons (step and controlled and continuous), Shift, Menu/Enable, LCD with contrast control, buzzer feedback
  • Step rate up to 75KHz
  • Configurable steps/rev and units/rev for accurate translation of rotational to linear/rotational motion
  • Backlash compensation support
  • Adjustable Speed/RPM via potentiometer (even when in motion) (with configurable maximum speed).
  • Bouncing: Reverses the motor on triggering a hardware limit (limit switch) or a software limit (when axis is homed), on Forward, Backward or for both directions.

Controls / Jogging:

  • Continuous movement, after long press of A- / A+
  • Controlled movement, while B- / B+ are pressed
  • Step Mode: cycle through predefined step sizes with UP / DOWN

Units

  • Μetric: Position units mm
  • Ιmperial: Position units inches
  • Degrees: Position units degrees

Where to start

  • See Wiring for pinouts and sensor/driver wiring modes.
  • Use Settings to shape motion behavior, pin polarities, and units.
  • Check Usage for button combos, step/continuous jogging, and how to enter/exit the menu.
  • For homing behavior and safety, read Limits & Homing.
