The Autonics MD2U-MD20 2-Phase Stepper Motor Driver operates on a unipolar constant current drive, supporting 2-phase stepper motors for stable and accurate positioning. It provides multiple resolution modes including FULL STEP (1-division), HALF STEP (2-division), and Micro STEP with 4, 5, 8, 10, 16, and 20 divisions, giving engineers flexibility in speed and torque control. The driver is powered by a 24โ35VDC supply, delivering a maximum run current of 2A per phase and peak consumption of 3A, making it suitable for demanding industrial tasks. With an input pulse frequency of up to 50kHz, fast response is ensured even in high-speed applications. The compact design, weighing around 295g, is engineered for reliability under industrial conditions with an ambient operating range of 0โ50โ and humidity tolerance of 35โ85% RH.
The Autonics MD2U-MD20 Stepper Motor Driver is widely used in CNC machines, packaging systems, pick-and-place robotics, printing presses, and conveyor automation. Its micro-step resolution enhances smooth motion, making it ideal for industries that demand precision control in small incremental movements. Maintenance engineers value its durability in tough factory conditions, while design engineers prefer the flexibility in speed-torque tuning. With its robust build, reliable performance, and trusted Autonics automation technology, this driver is a preferred choice across Indian industries, from automotive manufacturing to electronics assembly lines.
