5.6.4 Flowchart of Semi-Auto Tuning
Set P2-32 to 2 (semi-auto mode, non-continuous tuning)
After tuning for a while and wait until the system inertia is stable, it stops estimating. The estimated
inertia ratio will be saved to P1-37. When switching mode from manual or auto to semi auto, the
system starts tuning again. During the process of estimation, the system will refer the stiffness and
bandwidth setting of P2-31.
P2-31 Response setting in auto 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
851 ~ 1000 Hz: extremely high-stiffness, extremely high-response
Response setting in semi-auto tuning mode: the bigger the value is, the better the response will be.
Adjust the value of P2-31: Increase the value of P2-31 to increase the response or decrease to
reduce the noise. Continue to tune until the performance is satisfied. Then, tuning is completed.
NOTE
1. If P2-33 bit 0 is set to 1, it means the inertia estimation in semi-auto mode is completed. The result can be
accessed by P1-37.
2. If the value of P2-33 bit 0 is cleared to 0, the system will start to estimate again.
