5.5.4 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
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.
1. Decrease the value of P2-31 to reduce the
noise.
2. If not desire to decrease the value of P2-
31, the value of P2-23 and P2-24 can be
used to suppress the resonance as well.
1. When bit0 of P2-33 is set to 1, it means the inertia estimation in
