POEM Stepper Organizer specifications

Main characteristics

Axes and I/O count 4 axes with limits, 4 inputs, 4 outputs per one parallel port with software selectable pin layout. Software velocity and acceleration calibration for different axes.
Position range -2,147,483,648 to 2,147,483,647 pulses.
Maximum velocity hardware dependent: 4,000 pulses per second on 386SX 16MHz, 21,000 pulses per second on 486DX 33MHz, 77,000 pulses per second on Pentium 100MHz.
Acceleration 0 to 2,147,483,647 pulses per second?.
Position accuracy and repeatability ? 0 counts.
Velocity Accuracy ? 0.055% of peak velocity.
Moving mode linear (using linear interpolation) or rapid (as rapidly as possible according to main axis peak velocity).
Positioning relative (incremental) or absolute.
Contouring continuous or nudge path travel; all axes simultaneously.
Inputs (limit switches etc) TTL input levels, requires only external switchclosure to ground TTL level input. Input sence (low or high true) selectable by software.
Outputs (step, direction, control) open collector TTL level signal. Pulse width ~ 50% duty cycle. Base direction can be changed by software.
Memory requirement 42 Kb (conventional or upper) per each parallel port.
Lanquage support direct program access, ASCII-oriented or optionally any motion control language.
Software driver type DOS: linkable or resident, Windows 3.1x/9x/ME/NT/2000/XP: DLL.
