What are the basic requirements for servo drives?
1. Wide speed regulation range;
2. High positioning accuracy;
3. Having sufficient transmission rigidity and high speed stability;
4. Fast response and no overshoot (in order to ensure productivity and processing quality, in addition to high positioning accuracy, servo drives also require good fast response characteristics, that is, fast response to tracking command signals, because the CNC system requires sufficient acceleration and deceleration during startup and braking, shortening the transition time of the feed system and reducing contour transition errors);
5. Low speed high torque, strong overload capacity (generally speaking, servo drives have an overload capacity of 1.5 times or more within minutes or even half an hour, and can overload 4-6 times in a short period of time without damage);
6. High reliability (requires the feed drive system of CNC machine tools to have high reliability, good working stability, strong adaptability to environments such as temperature, humidity, vibration, and strong anti-interference ability).
