Fastech is dedicated to the development and production of new products in the field of motion control using DSP technology. Since its inception in 2001, they have been successful in meeting customer’s needs. In 2007 Fastech went global and has had much success with its High-Precision, High-performance Closed Loop Stepping Motor Driven, Control Sytem, “Ezi-SERVO”, which it is currently exporting to more than 50 countries and is being used by approximately 560 equipment makers or companies.

Difference between Closed Loop Stepping Motor System and Conventional Servo Systems

Conventional servo systems, to ensure machine performance, smoothness, positional error and low servo noise, require the adjustment an initial step. Even systems that employ auto-tuning require manual tweaking after the system is installed, especially if more than one axis are interdependent. Ezi-SERVO employs the best characteristics of stepper and closed loop motion controls and algorithms to eliminate the need of tedious gain tuning required for conventional closed loop servo systems. This means that Ezi-SERVO is optimized for the application and ready to work right out of the box. The Ezi-SERVO system employs the unique characteristics of the closed loop stepping motor control, eliminating these cumbersome steps and giving the engineer a high performance servo system without wasting setup time.

Beats Open-loop Control Stepping Drives

At 3000 rpm Ezi-SERVO is reliable for positioning without loss of synchronism. Holding a stable position and automatically recovering to the original position even after experiencing positioning error due to external forces, such as mechanical vibration or vertical positional holding. Ezi-SERVO utilizes 100% of the full range of rated motor torque, compared to a conventional open-loop stepping driver that can use only up to 50% of the rated motor torque due to the loss of synchronism. With the capability to operate at high speeds due to load-dependant current control, open-loop stepper drivers allow a constant current control at all speed ranges.
