Siemens SINAMICS G115D Operating Instructions Manual page 309

If you are using a Siemens motor, then the converter automatically selects the appropriate
technique to determine the pole position.
Each time the motor is switched on (ON/OFF1 command), the converter identifies the pole
position.
Figure 7-10
As a result of the pole position identification, the motor responds to an ON command with
a delay of up to 1 second. The motor shaft can rotate slightly during the pole position
identification.
