Description
The intelligent 750‐672 Stepper Controller has an on-board power driver designed to control 2-phase stepper motors up to 70 V/7.5 A. The 64 times microstepping prevents step losses due to resonance in the acceleration phases and reduces wear on the mechanical parts. Adjustable current limits for stop, acceleration and constant speed help minimize motor power dissipation. Six configurable inputs for start/stop, limit switches, reference cams, jog/tip, etc., are directly processed by the internal software without delay. Two outputs can be linked with internal functions or used freely.Versatile functions, such as positioning with different acceleration slopes, command tables, camshaft controller, auto referencing and other event-dependent properties provide this controller with a wide spectrum of possible uses. The programmer’s interface is the same for all WAGO Stepper Controllers.
