503-26606-21 Technical specifications of DANAHER
503-26606-21 Servo drive technology, as one of the key technologies of CNC machine tools, I industry robots and other industrial machinery control, has been widely concerned at home and abroad. In the last decade of the 20th century, little
Processing equipment (especially digital signal processors
The development of DSP technology, power electronics technology, network technology and control technology has laid a good foundation for the further development of servo drive technology. Say 20
In the 1980s, AC servo drive technology replaced DC servo drive technology, then the 1990s is the servo drive system to achieve full digital, intelligent, networked 10 years. this
This is particularly evident in some industrially developed countries.
503-26606-21 Servo drive is divided into position ring, speed ring and current ring according to its control object from outside to inside, and the corresponding servo drive can work in position control mode, speed control mode and speed control mode
Torque control mode. When the servo drive works in any mode, its corresponding mode can be set by three ways: 1. 2. Internal setting of parameters; 3, communication given.
The internal given application of the parameter setting is relatively small, and it is limited graded adjustment.
503-26606-21 The advantage of using analog quantity given is that the response is fast, applied to many high-precision and high-response occasions, the disadvantage is that there is zero drift, which brings difficulties to debugging, European and American servo systems use this
Way. Pulse control is compatible with common signal modes: CW/CCW (positive and negative pulse), pulse/direction, and A/B trust signal. The disadvantage is that the response is slow, and Japanese and domestic servos use this way.
503-26606-21 Of course, I most recommend the way of communication given, which is also the common control method of European brands, the advantages are quick to give, fast response, reasonable motion planning, especially suitable for CAM control
System and flying positioning method, high-grade CNC machine tools in 2012 are mostly used in this way. Communication is usually given as bus communication, point-to-point communication and network communication.
