Siemens SIPROTEC 5 Manual page 173

Measurement of the motor statistics starts when the motor state changes to Start. Measurement of the
motor starting time ends as soon as the motor state changes to Standstill or Running. The motor state is
obtained from the Motor-state detection function.
No entry is recorded in the motor-starting log if the motor state changes to Start and the current drops
below the motor starting current within 500 ms.
