Closed Loop Stepper Driver 0-8.2A 18-80VAC/24-110VDC for Nema 34 Stepper Motor

This Closed-loop Stepper offers an alternative for applications requiring high performance and high reliability when the servo was the only choice, while it remains cost-effective. The system includes a 2-phase stepper motor combined with a fully digital, high performance drive and an internal encoder which is used to close the position, velocity and current loops in real time, just like servo systems. It combines the best of servo and stepper motor technologies, and delivers unique capabilities and enhancements over both, while at a fraction of the cost of a servo system.

Key Features:

• No Tuning and always stable
• Do not need a high torque margin
• Reduced motor heating and more efficient
• Smooth motion and super-low motor noise
• Closed-loop, eliminates loss of synchronization
• 5V/24V logic voltage selector, default setting 24V
• Quick response, no delay and almost no settle time
• Offer servo-like performance at a much lower cost
• Broader operating range - higher torque and higher speed
• High torque at starting and low speed, high stiffness at standstill
