Y2SD2-U Advanced Stepper Driver for Two-Phase Motors

The Y2SD2-U stepper driver is an advanced solution designed for controlling two-phase stepper motors, providing high-precision control and adaptability for various industrial applications. Supporting motors of size 86 and below, this driver offers robust performance with an input power range of 24 to 70V DC (±15%) and a peak current output of up to 7A, making it ideal for motors requiring powerful yet precise control.

The compact design, with installation dimensions of 118 × 75.5 × 33 mm, allows for easy integration into existing systems, even in limited spaces. The Y2SD2-U is equipped with multiple control modes, including Pulse + Direction (default), dual pulse, single-segment speed, and two-segment speed modes, all of which can be switched through software for maximum flexibility. This versatility makes it suitable for a wide range of applications, from automated machinery to robotics.

This driver features a TTL serial port for communication, ensuring smooth integration into automation systems. The digital signal inputs for pulse, direction, and enable are opto-isolated, supporting differential signals with a common end that accommodates 5~24VDC and a maximum frequency of 500KHz, ensuring reliable signal transmission even in demanding environments. The output signal includes an alarm with opto-isolation, capable of handling up to 100mA at 30V, which provides an added layer of safety and error detection.

One of the standout features of the Y2SD2-U is its adjustable current and speed settings. Current tap positions can be adjusted via a dial to select values between 1.0A and 4.5A, while software settings allow for more precise control, with values ranging from 0.1A to 7.0A. The subdivision tap positions (pulse mode) can also be adjusted via a dial, offering options from 400 to 25,600 steps, with the software allowing any even number between 200 and 51,200 for fine-tuned motor resolution.

In speed mode, the tap position offers values ranging from 0.5 to 10.0 rps, while the software provides a broader range, from 0.01 to 50.0 rps, making it highly adaptable to different operational speeds. This level of flexibility ensures that the Y2SD2-U can be customized for a variety of motor applications, from precise positioning to high-speed operations.

The driver is designed for durability, with an operating temperature range of 0 to +55°C, and is capable of functioning in environments with humidity levels below 90%RH. It is suitable for altitudes up to 1000 meters and is resistant to dust and corrosive gases, although care must be taken to avoid contact with water and oil.

Built to withstand harsh conditions, the Y2SD2-U has a dielectric strength of AC1.5KV between ground wires and can endure high-voltage stress for up to one minute. Its IP20 protection grade ensures reliable performance in industrial environments. Weighing only 0.25kg, the Y2SD2-U combines portability and power, making it an excellent choice for controlling two-phase stepper motors in a variety of applications.
