Siemens SINAMICS V90 Operating Instructions Manual page 263

If the dynamic factor setting cannot be increased up to the desired level because of machine
resonance beyond 250 Hz, the function of resonance suppression can be used to suppress
machine resonance and thus increase dynamic factor. Refer to Section "Resonance
suppression (Page 270)" for detailed information about the function of resonance
suppression.
Note
The tuning configuration parameters must be set carefully when the auto tuning function is
disabled (p29021=0).
After servo on, the motor will run with the test signal.
When the one-button auto tuning process completes successfully, parameter p29021 will be
set to 0 automatically. You can also set the parameter p29021 to 0 before servo on to
interrupt the one-button tuning process. Before you save the parameters on the drive, make
sure that p29021 has changed to 0.
When the one-button auto tuning process completes successfully, bit 0 of parameter p29300
will be set to 0 automatically or remain unchanged (= 0), which means the drive is in "S OFF"
state.
Note
Do not use the JOG function when you use the one-button tuning function.
Note
After the one-button tuning is activated, no operation will be allowed except the servo off and
emergency stop.
With one-button auto tuning, the servo drive can automatically estimate the ratio of load
moment of inertia and set the following relevant parameters accordingly.
