Motion control module-(pulse train, analog command)
is a module used in industrial automation The open communication protocol was first developed by Yaskawa Electric and later maintained by the association.
The protocol is divided into the following two types:
- A communication protocol architecture that defines the transmission interface. The maximum speed is b/, and a maximum of slave stations are allowed.
Servo controller control mode
According to the needs of different control systems, there are three control modes to choose from in the driver:
.Position control mode
.Torque control mode
3. Speed control mode
Position control mode
The position control mode generally determines the rotation speed through the frequency of externally input pulses, and determines the rotation angle through the number of pulses. Some servos can also Speed and displacement are assigned directly through communication. Since the position control mode can strictly control both speed and position, it is generally used for positioning control.
Application areas include CNC machine tools, printing machinery, robots, etc.
Torque control mode
The torque control mode is to set the external output torque of the motor shaft through external analog input or direct address assignment. The specific realization is: for example, when the external When the analog value is set to , the motor shaft output is . If the motor load is lower than ., the motor will rotate forward. If the external load is equal to ., the motor will not rotate. When it is greater than . The set torque can be changed by changing the analog setting in time, or by changing the corresponding value through communication.
It is mainly used in winding and unwinding positions that have strict requirements on the stress of the material, such as winding devices or optical fiber drawing equipment. The setting of the torque should be changed at any time according to the change of the winding radius to ensure that the material is stressed. The force does not change as the winding radius changes.
Speed control mode
The speed control mode can control the rotation speed through analog input or pulse frequency. The speed mode can also perform positioning during the outer loop control of the upper control device, but it must be Feed back the position signal of the motor or the position signal of the direct load for calculation purposes. The position mode also supports direct load outer ring detection of position signals. At this time, the encoder on the motor shaft end only detects the motor speed, and the position signal is provided by the direct monitoring device on the final load end. This has the advantage of reducing the need for intermediate transmission. error, enhancing the positioning accuracy of the entire system.
The relationship between servo drive and frequency converter
Both are used to control the rotation of the motor, but the frequency converter focuses on speed regulation, while the servo drive focuses on position control. The frequency converter rectifies AC power at the power frequency into DC power, and then inverts it into a frequency-adjustable waveform similar to a sine and cosine pulse current through various transistors that can control the gate through the carrier frequency and adjustment. , so the speed of the AC motor is adjustable. The servo drive has more powerful functions than these and is more user-friendly. As the name suggests, the servo drive can complete some operations without manual labor. The frequency converter can only complete a single operation and requires manual support.
