Kollmorgen 63025-01D servo drive is an important part of modern motion control, and is widely used in industrial robots and CNC machining centers and other automation equipment. In particular, the servo drive used to control AC permanent magnet synchronous motor has become a research hotspot at home and abroad. The current, speed and position three closed-loop control algorithms based on vector control are widely used in the design of AC servo drivers. Whether the speed closed-loop design in this algorithm is reasonable or not plays a key role in the whole servo control system, especially in the performance of speed control .
Kollmorgen 63025-01D In the servo drive speed closed loop, the real-time speed measurement accuracy of the motor rotor is very important to improve the dynamic and static characteristics of the speed control of the speed loop. In order to find the balance between measurement accuracy and system cost, incremental photoelectric encoder is generally used as the speed measurement sensor, and its corresponding common speed measurement method is M/T speed measurement. Although M/T velocity measurement method has a certain measurement accuracy and a wide measurement range, but this method has its inherent defects, including: 1) the speed measurement cycle must detect at least one complete code pulse, limiting the minimum measurable speed; 2) The timer switches of the two control systems used for speed measurement are difficult to maintain strict synchronization, and the accuracy of speed measurement cannot be guaranteed in the measurement occasions with large speed changes. Therefore, it is difficult to improve the performance of servo drive speed following and control by using the traditional speed loop design method
Kollmorgen 63025-01D mainstream servo drivers all use digital signal processor (DSP) as the control core, which can realize more complex control algorithms, and realize digitalization, networking and intelligence. Power devices generally use intelligent power module (IPM) as the core design of the drive circuit,IPM internal integrated drive circuit, and has overvoltage, overcurrent, overheating, undervoltage and other fault detection protection circuit, in the main circuit also add a soft start circuit to reduce the impact of the start process on the driver. The power drive unit first rectifies the input three-phase or mains through the three-phase full-bridge rectifier circuit to obtain the corresponding direct current. The three-phase permanent magnet synchronous AC servo motor is driven by the three-phase sinusoidal PWM voltage inverter after the rectified three-phase power or mains. The whole process of the power drive unit can be simply said to be the AC-DC-AC process. The main topological circuit of the rectifier unit (AC-DC) is the three-phase full-bridge uncontrolled rectifier circuit.
Kollmorgen 63025-01D With the large-scale application of servo system, the use of servo drive, servo drive debugging, servo drive maintenance are more important technical issues in today’s servo drive, more and more industrial control technology service providers have conducted in-depth research on servo drive technology.
