Servo drive is an important part of modern motion control, which is widely used in industrial robots and CNC machining centers and other automation equipment. It is used to control the servo of AC permanent magnet synchronous motor
The actuator 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. The velocity closed-loop design in this algorithm is suitable
It plays a key role in the whole servo control system, especially in the performance of speed control.
In the speed closed loop of servo drive, the real-time speed measurement accuracy of motor rotor is very important to improve the dynamic and static characteristics of speed control of speed ring. To find the balance of measurement accuracy and system cost, - general
The incremental photoelectric encoder is used as a speed measurement sensor, and the corresponding speed measurement method is M measurement method. Although the M/T velocity measurement method has a certain measurement accuracy and a wide measurement range, this method
There are inherent defects, including: 1) the speed measurement cycle must detect at least a complete code pulse, limiting the minimum measurable speed; 2) It is difficult to switch the timer of the two control systems of speed measurement
In order to maintain strict synchronization, the measurement accuracy cannot be guaranteed in the measurement occasions with large speed changes. Therefore, it is difficult to improve the speed following and control of servo drive by using the traditional speed loop design method
The main functions of the S72402-NANANA-NA Kollmorgen servo drive include:
Precise control: The servo amplifier can precisely control the movement of the servo motor, so that it can move in accordance with a predetermined position, speed and acceleration, suitable for applications requiring high-precision control.
Peak current control: Allows for short-term overload and higher torque output.
ADAPTS to a wide range of connections: Many popular EtherNet fieldbuses such as EtherCAT, EtherNet/IP, Profinet and SynqNet are supported. Some models also support traditional fieldbuses, including Profibus, Devicenet, CanOpen, RS485, RS232, and Sercos II.
Integrated Safety features: For example, the S700 and AKD2G servo drives have integrated safety features that allow machine manufacturers to create inherently safer machines with flexible safety zones, with less wiring and configuration than ever before.
Pairing with a wide range of motor families: Servo drives are typically paired with our extensive Kohmorgen servo motor family, which offer the most popular feedback support on the market (including rotary transformers, incremental encoders, BiSS, EnDat, Hiperface, sinusoidal encoders).
In terms of application, due to its precise control and adaptability to a wide range of connections, the S72402-NANANA-NA servo drive is often used in situations requiring high precision control and fast response. For example, in the fields of CNC machine tools, robots, automated production lines, etc., the movement and position of the motor need to be precisely controlled to ensure the precision and stability of the machine. At the same time, due to its integrated safety features, it can also be used in situations requiring a high degree of safety, such as emergency stop systems in industrial automation production lines.
