1. Torque control mode: the torque control mode is to set the output torque of the motor shaft through the input of external analog quantity or the assignment of the direct address, which is manifested in the specific performance of 10V corresponding to 5Nm, when the external analog quantity is set to 5V, the output of the motor shaft is 2.5Nm: if the motor shaft load is lower than 2.5Nm, the motor rotates, the motor does not rotate when the external load is equal to 2.5Nm, and the motor reverses when it is greater than 2.5Nm (usually generated under the condition of gravity load). The set torque can be changed by changing the setting of the analog quantity in real time, and the value of the corresponding address can also be changed by means of communication. The application is mainly in the winding and unwinding device that has strict requirements for the force of the material, such as the wire rao device or the optical fiber pulling equipment, the setting of torque should be changed at any time according to the change of the winding radius to ensure that the force of the material will not change with the change of the winding radius.
2. Position control mode: The position control mode is generally to determine the size of the rotation speed through the frequency of the external input pulse, and the rotation angle is determined by the number of pulses, and some servos can directly assign the speed and displacement through communication. Since the position mode can have a very tight control of speed and position, it is generally used in positioning devices. Application fields such as CNC machine tools, printing machinery and so on.
3. Speed control mode: the rotation speed can be controlled by the analog input or the frequency of the pulse, and the speed mode can also be positioned when the outer ring PID control device is controlled by the upper control device, but the position signal of the motor or the position signal of the direct load must be given to the upper feedback for calculation. The position mode also supports the direct load outer ring to detect the position signal, the encoder at the motor shaft end only detects the motor speed, and the position signal is provided by the detection device at the direct final load end, which has the advantage that the error in the intermediate transmission process can be reduced, and the positioning accuracy of the whole system is increased.
