The law CNC robot servo drives are the first domestic product by ETG conformance testing, it is possible to fit well with the controller; at the same time, built-in current loop, velocity loop and position loop cycle times are achieved 62.5μS, 125μS and 250μS frequency response is as high as 3kHz, fully meet the industrial robot dynamic response and synchronization requirements。
For vibration problem robot, the law CNC robot servo drives added speed, feed-forward compensation acceleration, torque compensation compensation algorithm, and the development of positioning Jitter, before inertia feed-forward functions, a better solution to the robot body at high speeds , vibration generated when rapid positioning. In addition, the law CNC robot servo drives also increased the weakening of the motor control technology to achieve high-speed operation of the robot light load, increasing the signal correction encoder robot technology to improve stability and reduce running noise。
The law CNC robot servo drive servo domestic manufacturers are still using innovative modular design. The system consists of rectifier modules and motor drive modules, connected by the DC bus. Such a structure facilitates user system expansion, and the connection is very simple, the DC bus can improve energy efficiency of the system, making the equipment more energy efficient. The law CNC robot servo drive also comes with a STO, SS1 and SS2 and other security features, in case of an emergency in accordance with predetermined rules prior secure parking, to protect the safety of equipment and personnel。
