Motor-Starting Log

The motor-starting log records the starting current, starting voltage and the start duration each time a motor
starts. The motor-starting current and the motor-starting voltage are displayed as primary values. Up to 200
indications can be stored in the motor-starting log.
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.
