The ST5-S can be controlled by a step and direction input, or by a host controller via serial communications. Self-Test and Auto Set-up features measure and configure motor parameters automatically, while anti-resonance technology eliminates midrange instability for higher motor speeds and fuller use of available torque. Other features include Demand Signal Smoothing, Torque Ripple Smoothing and MicroStep Emulation. Using the vendor’s Configurator software, the drive can be configured from a drop-down menu, or the user can quickly create custom motor configurations, if desired.Applied Motion Productswww.applied-motion.com800.525.1609
