What are the basic requirements for servo drives?

What are the basic requirements for servo drives? Here we say:

1, Server Driver wide speed range

2, Server Driver high positioning accuracy

3, Server Driver there is sufficient transmission rigidity and high speed stability

4, Server Driver fast response, no overshoot (in order to ensure productivity and processing quality, in addition to requiring a higher positioning accuracy, the servo driver also requires a good fast response characteristics, that requires tracking the signal response to the signal faster, because the CNC system In the start, brake, the requirements of Canada, reduce the speed is large enough to shorten the feed system transition process time, reduce the contour transition error)

5, Server Driver low-speed large torque, overload capacity (in general, the servo drive with a few minutes or even half an hour more than 1.5 times the overload capacity, in a short time can be overloaded 4 to 6 times without damage)

6, Server Driver high reliability (requires CNC machine tool feed drive system reliability, work stability, and has a strong temperature, humidity, vibration and other environmental adaptability and strong anti-interference ability)
