Operating within the modular K-bus system, this compact drive terminal integrates a power stage for a stepper motor alongside a feedback interface for a 24 V DC single-ended incremental encoder. This integrated feedback loop enables precise, closed-loop positioning control in a compact physical form factor.\u003c\/p\u003e\n\u003cp\u003eBy supporting microstepping up to 64-fold, the \u003cstrong\u003eBECKHOFF KL2541\u003c\/strong\u003e ensures smooth motor operation, minimized resonance, and highly precise positioning. The terminal manages internal current control and features built-in travel distance control, offloading computational requirements from the central controller and allowing direct execution of positioning tasks.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eDirect motor connection interface for one stepper motor.\u003c\/li\u003e\n
