Y Series Closed Loop Stepper Driver V2.0 0-2.2A 24-50VDC for Nema 17 Stepper Motor

The CL42Y-V20 closed-loop stepper driver delivers superior performance with a current range of 0–2.2A and an operating voltage of 24–50VDC, making it ideal for Nema 17 stepper motors. As an upgraded successor to the CL42Y, it features a 5V/24V logic voltage selector and replaces the USB port with an RS232 debugging interface for enhanced compatibility and troubleshooting.
Utilizing next-generation 32-bit DSP control and power angle vector control technology, it achieves speeds exceeding 3000rpm. Compared to standard open-loop drivers, it significantly reduces high-speed torque decay, enhancing motor performance and torque utilization, which improves machining efficiency and accuracy. Its load-based current control effectively lowers motor heating, extending motor lifespan. The built-in alarm output facilitates easy monitoring and control by the host system, while the position error alarm ensures safe operation of the equipment.
