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.
Prerequisites 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
about two rounds when tuning starts
Implement the following steps to use the one-button auto tuning function:
1.
Select the dynamic factor in the following area:
For more information about selecting the dynamic factor, see the SINAMICS V90,
SIMOTICS S-1FL6 Operating Instructions.
2.
Configure the test signal in the following area:
Note:
The recommended position amplitude (p29027) is 360°.
3.
