138 138  When debugging with the host computer debugging software, automatic rigidity level measurement can be carried out, which is used to select a set of appropriate rigidity grades as operating parameters. The operation steps are as follows:
139 139  
140 -* Step1 Confirm that the servo is in the ready state, the panel displays “rdy”, and the communication line is connected;
141 -* Step2 Open the host computer debugging software, enter the trial run interface, set the corresponding parameters, and click "Servo on";
142 -* Step3 Click the "forward rotation" or "reverse rotation" button to confirm the travel range of the servo operation;
143 -* Step4 After the "start recognition" of inertia recognition lights up, click "start recognition" to perform inertia recognition, and the load inertia can be measured.
144 -* Step5 After the inertia recognition test is completed, click "Save Inertia Value";
145 -* Step6 Click "Next" at the bottom right to go to the parameter adjustment interface, and click "Parameter measurement" to start parameter measurement.
146 -* Step7 After the parameter measurement is completed, the host computer debugging software will pop up a confirmation window for parameter writing and saving.

233 233  The speed loop integral time constant is used to eliminate the speed loop deviation. Decreasing the integral time constant of the speed loop can increase the speed of the speed following. If the set value is too small, is will easily cause speed overshoot or vibration. When the time constant is set too large, the integral action will be weakened, resulting in a deviation of the speed loop. Related function codes are shown as below.

Increasing this parameter can speed up the positioning time and improve the ability of the motor to resist external disturbances when the motor is stationary. However, if the setting value is too large, the system may be unstable and oscillate. The related function codes are shown as below.
