Precision Stepper Motor Control for Industrial Automation – WAGO 750-671
The WAGO 750-671 is an intelligent stepper controller module with an integrated on-board power driver, specifically designed for controlling 2-phase bipolar stepper motors. Part of the WAGO I/O System 750, this module provides a complete motion control solution for demanding industrial automation applications.
The module delivers up to 24 VDC at 1.5 A, making it suitable for a wide range of stepper motors. With 64x microstepping, the 750-671 ensures smooth motor operation, preventing step losses due to resonance and significantly reducing mechanical wear.
Two configurable digital inputs are processed directly by the internal software without delay, enabling fast response to end-stop, reference, and jog/tip signals. The module supports absolute and relative positioning, floating setpoint changes, rotary axis functions, command tables, camshaft functionality, and auto-referencing for a versatile range of applications.
The programmer’s interface is consistent across all WAGO stepper controller modules, simplifying development and allowing easy migration between different models. The module mounts on a standard 35mm DIN-rail and requires only 12mm of width, conserving valuable control cabinet space.
