5.5.3  Flowchart of Auto Tuning  
Set P2-32 to 1 (auto mode, continuous tuning) 
Continue to estimate the system inertia. Automatically save the value in P1-37 every  
30 minutes and refer the stiffness and bandwidth setting of P2-31. 
P2-31 Stiffness setting in auto tuning mode (The default value is 80) 
In auto and semi-auto mode, the bandwidth setting of speed circuit is: 
1 ~ 50 Hz: low-stiffness, low-response 
51 ~ 250 Hz: medium-stiffness, medium-response 
251 ~ 850 Hz: high-stiffness, high-response 
Stiffness setting in auto tuning mode: the bigger the value is, the stronger the stiffness will 
be. 
Adjust the value of P2-31: Increase the value of P2-31 to increase stiffness or decrease to 
reduce the noise. Continue to tune until the performance is satisfied. Then, tuning is 
completed.
