The servo system is employed as the main motion mechanism in the CNC machine tool industries. When the servo system is used, the electric and electronic devices, control system, driving structure and protection functions are all gathered in the servo drive. Therefore, after receiving the position and speed command from the CNC system, the servo motor and motion mechanism in the servo system will drive the coordinate axis and driving shaft of machine tool to control the working table or turret lathe. When the shaft rotates, the cutters of the turret lathe move and operate as well, and then complete every kind of demanding and complicated automation processes.

AC servo drive keeps leading position all along on the applications of machine tool industries. With the improvement of the technology, it can provide high-precision motion control for a wide range of industrial applications. The general AC servo drives can achieve the all-in-one and multi-use performance and satisfy the requirements of position, speed and torque control. In additional, it is able to receive pulse command and analog command, provide high stability and offer stronger self-diagnosis alarm function. The development of the current servo technology is moving forward and the trend is to provide the functions of Ethernet and fieldbus module, i.e. Profibus, DeviceNet, LonWorks and CANopen etc. With these communication modules, servo products are among the most flexible product lines in the industry and become a mainstream in the market.

Delta ASDA series servo products are applied in a board range of various machine tool industries. In response to the competitions from the market, Delta will launch the new-generation ASDA-A2 series which is suitable for the machine applications where high-speed, high-resolution and Network control structure is needed. ASDA-A2 series features high-resolution 20bit incremental encoder, communication network interface (CANopen / FlexRay) and full-closed loop control function (for linear scale and encoder).
