servo electric cylinderHow much do you know about the control method? Let's follow the servo electric cylinder editor to understand it!
1. Torque control:servo electric cylinderThe torque control method is to set the output torque of the motor shaft through external analog input or direct address allocation. For example, 10V corresponds to 5Nm. When the external analog setting is 5V, the output of the motor shaft is 2.5Nm. When the motor shaft load is less than 2.5Nm, when the external load is equal to 2.5Nm, the motor does not rotate, and when it is greater than 2.5Nm, the motor reverses (usually in the case of gravity load). The torque can be changed by changing the setting of the analog quantity, or the value of the corresponding address can be changed by communication.
2. Position control: position control mode is generally through the external input pulse frequency to determine the size of the rotation speed, through the number of pulses to determine the rotation angle, some servo can be directly through the communication mode of speed and displacement assignment. Because the position mode can have very strict control of speed and position, it is generally applied to positioning devices.
3. Speed mode: The rotation speed can be controlled by analog input or pulse. When the upper control device in the outer ring of PID control can also position the frequency of the speed mode, but it must be the position signal of the servo cylinder or the electric load position signal sent directly to the host computer for feedback calculation processing. The mode also supports the position of the outer ring. At this time, the motor shaft encoder only detects the motor speed. The position signal is provided by the end detection device on the direct load side. The direct support position detection signal can make the following advantages, that is, the error in the intermediate transmission process can be reduced, thereby increasing the positioning accuracy of the entire system.
