Description

Achieve the ultimate in positioning accuracy with the Delta ASDA-A2-L Servo Drive. This specialized model from the high-performance A2 series is engineered specifically for applications that require Full-Closed Loop Control. By utilizing a second feedback channel from an external encoder or linear scale mounted directly on the load, the ASDA-A2-L can compensate for mechanical inaccuracies such as backlash, hysteresis, and thermal expansion, ensuring that the final load position is perfect every time.

Eliminating Mechanical Inaccuracy

In standard servo systems, the drive only knows the position of the motor shaft. Mechanical components between the motor and the load (like gearboxes, ball screws, and belts) can introduce small but significant positioning errors. The ASDA-A2-L solves this problem by reading a second encoder placed at the actual point of motion. The drive’s advanced control algorithm then compares the motor’s position with the load’s real position and makes micro-adjustments in real-time to eliminate any discrepancy. This makes it the ideal solution for high-precision machine tools, CNC systems, semiconductor inspection stages, and other applications where absolute accuracy is paramount.

Built on a High-Performance Platform

While its specialty is full-close loop control, the ASDA-A2-L retains all the other high-performance features of the A2 series. This includes a 1kHz frequency response for rapid dynamics, a 20-bit primary encoder for smooth motor control, and advanced features like auto-tuning and vibration suppression. This ensures that the entire system, from motor to load, is stable, responsive, and easy to commission. By choosing the ASDA-A2-L, you are not just getting a drive; you are implementing a comprehensive solution for high-accuracy motion control.

Core Specifications

When your application demands flawless positioning and cannot tolerate mechanical errors, the Delta ASDA-A2-L is the definitive choice for achieving true high-accuracy motion control.
