This driver is brand Leadshine (The most famous stepper driver company in China), and STEPPERONLINE is the biggest distributor of Leadshine in China.

This is one of Leashine’s ES-D series easy servo drives. It can be used for applications requiring high performance and high reliability where servo drives used to be the only choice. It combines the best of servo and stepper technologies and delivers the full advantages of both while it is still cost-effective. It is used to drive a stepper motor integrated with an encoder. A high torque matgin is not necessary any more when using the easy servo system.

Key Features                                                                                                                            

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