|Axis and I/O count||up to 4 axes with limits, 4 inputs, and 4 outputs with software selectable
pin layout; software velocity and acceleration calibration for different axes.
|Position range||-2,147,483,647 to 2,147,483,647 steps.|
|Maximum velocity||20,000 steps per second.|
|Acceleration||trapezoidal, 0 to 2,147,483,647 steps per second per second.|
|Motion mode||rapid (as rapidly as possible according to main axis peak velocity), linear
(using linear interpolation), and circular/helical (using helical interpolation).
|Contouring mode||exact path (auto stop), exact stop (nudge), and continuous travel.|
|Positioning mode||relative (incremental) and absolute distance.|
|Inputs (limit switches,
|TTL input levels, internally pulled up, only external switchclosure to ground
required; software selactable input sense (low or high true).
|TTL level signal; pulse width ~ 25 microseconds; polarity of step, direction
and other outputs can be changed (inverted) by software.
|Special features||positive and negative limits may share the same input pin with ability to be
checked separately according to related axis direction value; in similar way
positive and negative limits may be shared with the related axis step pin.
|Interface to host||virtual standard COM port through USB bridge @ auto-baud up to 1 Mbps
(and embedded serial TTL option @ auto-baud up to 4 Mbps).
|Interface to drivers||DB25 plug (female) with standard LPT port-like pinout.|
|Language interface||G-code-friendly and G-code-transparent command set.|
|Applications:||robotics, CNC, pan/tilt/zoom systems - industrial, educational and hobbyist projects|
