EvoDrive ST-23



We believe that by bringing you the very latest technology, we can help you create an outstanding product.

That’s why we created the EvoDrive ST-23. It embodies the very latest motor control theory in an easy to use package.

The EvoDrive ST-23 is not just another micro-stepping controller. It can provide true servo-motor precision and performance using any standard NEMA Frame 23 stepper motor.

This means that in closed loop operation, your stepper motor will

-   Actively maintain position.
-   Run silently and smoothly.
-   Keep your motor cool – it runs only a few degrees above ambient.

Even when used as an open-loop controller (no encoder feedback), the EvoDrive ST-23 still provides the equivalent of 512 microstep accuracy with exceptionally smooth current control, resulting in incredibly quiet and smooth motion.

The EvoDrive ST-23 operates from 12V - 48V DC and can drive any bipolar stepper motor with up to 3 Amps. The EvoDrive ST-23 can interface to almost any incremental encoder for closed-loop feedback (min 8 192 resolution).

The EvoDrive ST-23 is easy to interface to external systems using RS232, RS485, USB, or digital signals (PULSE/DIR and CW/CCW). This combined with the simple and intuitive ASCII based command set will accelerate your development time and make debugging easy.
