One-Button Auto Tuning - Siemens SINAMICS V90 Operating Manual

● Real-time auto tuning
– Real-time auto tuning estimates the machine load moment of inertia automatically

One-button auto tuning

Note
Before using the one-button auto tuning, move the servo motor to the middle of mechanical
position to avoid approaching the actual machine position limit.
With one-button auto tuning, the servo drive can automatically estimate the ratio of load
moment of inertia.
Pre-conditions for one-button auto tuning
● The ratio of machine load moment of inertia is unknown and needs to be estimated.
● The motor is allowed to rotate clockwise and counter clockwise.
● The motor rotation position (p29027 defines that one revolution equals to 360 degree) is
allowed by the machine.
– For the motor with an absolute encoder: position limitation is defined by p29027
– For the motor with an incremental encoder: the motor must be allowed to rotate freely
Implement the following steps to use the one-button auto tuning function:

while the drive is running with the host controller command. After enabling the servo
on (SON), the real-time auto tuning function stays effective for the servo drive. If you
do not need to estimate the load moment of inertia continuously, you can disable the
function when the system performance is acceptable.
