Part Number: 2YF2-ST2811MA ## Function Two-phase stepper motor drive implementing PWM current chopping with microstepping to regulate winding current for precise angular positioning. Accepts step, direction, and enable signals; provides adjustable current limit and decay mode for torque control and thermal management. Supports programmable acceleration, deceleration, and max step rate for smooth motion, with hold torque when stationary. Monitors fault conditions (overcurrent, overtemperature, short circuit) and reports status; suitable for automated positioning, pick-and-place or CNC-type motion systems seeking repeatable, high-resolution step responses. ## Images - - - -
