A High Precision Linear Drive System for Backlash Free Motion Control
The ASDA-A2R series is an innovative and high precision linear drive system that optimally performs the tasks of linear motors with high prevision, high rigidity, high response and it is backlash free. This not only increases the work efficiency of the motion control system, but also expands the applications of the servo system.
Delta’s high-performance ASDA-A2R series offers high frequency response, auto notch filters, vibration suppression, flexible position register control PR mode, build-in electronic cam (E-Cam) and advanced gantry control, and it supports DMCNET and CANopen communication interfaces as well. The ASDA-A2R harmonizes linear motion and servo drive to satisfy demanding high precision requirements.
The ASDA-A2R provides more choices and allows users to drive not only Delta’s but also other brands of linear motors and permanent magnet synchronous servo motors. When the ASDA-A2R is connected to an optional ADS-IF-EN0A20 Signal Converter Box through a motor encoder interface, the square waves and sine waves of feedback signals from the linear scale, linear motor and encoder can be converted to communication signals into the ASDA-A2R. The distortion provides more accurate signal transmission that is essential for fast and optimum communications.
Good stability, high reliability and excellent performance are the features of Delta’s ASDA-A2R series linear motion drive.
