Torque control: Torque control is based on external simulation imitation typing or direct address assignment to set the output torque of the motor shaft. For example, 10V matches 5Nm. When the external simulation simulation is set to 5V, the output of the motor shaft is 2.5Nm. If the load on the shaft of the motor is less than 2.5 Nm, the motor will not simply roll when the external load is equivalent to 2.5 Nm (beyond 2.5 Nm). When the motor is turned over (generally under force load). It is possible to change the setting of torque by changing the setting of the imitation amount on the fly, or by changing the value of the relative address according to the communication.

This application is suitable for winding and unwinding equipment that has strict management of raw material forces, such as hanging wire equipment or fiber optic line driving equipment. The torque setting should be changed anytime and anywhere according to the change of the winding half-warp, so as to ensure that the raw material force is not simple and changes with the change of the winding half-warp.

2. Azimuth control: the general form of azimuth control is based on the frequency of the external input pulse, the speed ratio is clear, and the rolling angle is clear according to the number of pulses, and some servo drives can directly dispatch the speed and offset according to the communication. Because the azimuth form can harshly control the speed and bearing, it is generally used to locate the equipment. The main uses are CNC lathes, printing equipment, etc.

3. Speed form: The rolling speed can be controlled according to the simulation simulation type or single pulse frequency. When the outer ring PID of the control device can be used, it can also locate the speed form, but it is necessary to reflect the azimuth data signal of the motor or the azimuth data signal of the direct load to the top level for operation. The azimuth form also adapts to the outside of the direct load to check the azimuth data signal. At this time, the servo motor at the shaft end of the motor only checks the speed of the motor, and the azimuth data signal is directly supplied by the final load end inspection equipment. This advantage is due to the reduction of deviations in the center drive process and the improvement of the positioning accuracy of the entire system.

4. Talk about a three-loop system. Servo motors are generally operated by three circuits. To put it bluntly, the three circuits are three closed-loop control negative response PID control systems. The innermost PID circuit is the current circuit, which is implemented entirely inside the servo controller. The output current from the controller to the motor is checked according to the Hall components, and the negative reaction current is set according to the PID to adjust the output current as close to the set current as possible. The torque of the motor is controlled by the current loop, so that the operator operates in the torque form with minimal operation and daily dynamic response. It should be faster.

The second cycle is the velocity cycle. The negative response PID is adjusted by the data signal of the motor servo motor. The output of the PID in the loop is directly the setting of today's loop. Thus, the velocity loop includes a velocity loop and a current loop. In other words, the current loop must be used in all forms. The current circuit is fundamental to manipulation. In addition, the system is now in fact current-controlled. (torque) control for relative speed and azimuth control.

The third ring is the positioning ring, which is the outermost ring. Depending on the situation, it can be set up in the center of the controller and motor servo motor, as well as in the external controller and motor servo motor or final load center. Since the internal output of the azimuth control loop is the setting of the speed loop, the system operates all three circuits in the azimuth control form. At this time, the measurement volume of the system is quite large, and the daily dynamic response speed is relatively slow.
