The 750-671 is an intelligent stepper controller with on-board power driver
designed to control 2-phase stepper motors up to 24V/1.5A.
The 64 times microstepping prevents step losses due to resonance in the
acceleration phases and spares the mechanical parts.
Adjustable current limits for stop, acceleration and constant speed help
minimizing motor power dissipation.
Two configurable inputs for start/stop, end-stop, reference, jog/tip, etc., are
directly processed by the internal software without any delay.
Flexible functions such as positioning with various acceleration ramps,
command tables, camshaft, auto reference and other event-driven
characteristics provide for a wide range of applications.
The programmer's interface is the same for all WAGO stepper controller
modules.
