The Leadshine CL86C is a high-performance, closed-loop stepper motor driver (also known as a hybrid servo controller) designed to significantly upgrade the reliability and precision of industrial motion control systems. It effectively eliminates the risk of step loss, a common issue with traditional open-loop stepper systems, by utilizing encoder feedback. This technology combines the simplicity and cost-effectiveness of a stepper motor with the high-reliability and real-time correction of a servo system, resulting in improved torque output and higher operating speeds. The CL86C supports a wide input voltage range of 30-90V DC or 20-70V AC and delivers a powerful 8A peak output current, making it an ideal match for medium to large NEMA 34 stepper motors. Its RS232 interface allows for easy PC-based configuration and advanced tuning.
