Leadshine ES-D508 Easy Servo Drive (Closed loop Stepper Drive) with Maximum 20-50 VDC Input Voltage, and 8.0A Peak Current
By applying servo control on easy servo motors (stepper motors with encoders), Leadshine ES-D508 easy servo drive combines features of both open loop stepper drives and brushless AC servo drives. It takes step and direction control commands, 20-50 VDC input voltage, and outputs load-based current up to 8.0A. It is capable of powering 3-phase easy servo motors of NEMA 17/23/24, closing the position loop, and eliminating position tracking errors in real time.
Similar to brushless AC servo drives, an ES-D508 servo drive can take encoder feedback from driven DC input easy servo motors and close the position loop to eliminate possibility of lose of movement synchronization. Therefore, loss of steps commonly seen in open-loop stepper systems will never occur in ES-D508 driven easy servo systems. Compared with constant output current in open loop stepper drive, output current from a ES-D508 servo drive to the driven motor is load based. When torque requirement is low, the output current is automatically lowered to "just enough". But when the torque requirement is high, ES-D508 can boost the output current up to 8.0A. This can significantly lower down motor heating by up to 50% over open-loop stepper systems. There is no torque reservation needed for an ES-D508 driven easy servo system. You can always implement 100% of the driven stepper motor and thus improve system high speed performance by as much as 30% over open lop stepper systems. Smoothness, quietness (50% improvement), and acceleration (30% improvement) are also significantly improved in ES-D508 easy servo systems.
Compared with traditional brushless servo systems, cost of ES-D508 easy servo systems is much lower. They outperforms traditional brushless servo systems with the feature of much higher low-middle speed torque, high stiffness, quicker response time, no position hunting, no tuning / easy setup, no overshooting, and zero settling time.
ES-D508 easy servo systems have been widely adopted by many OEM clients to upgrade their open-loop stepper systems like CNC routers, laser cutting/marking/engraving machines, medical devices, and medical equipment. Many Leadshine clients have also chosen ES-D508 easy servo systems to replace their brushless servo systems to take easy servo's unique features, especially in many bonding type machines and electronic equipment which requiring constant stops and rapid motion.
