ZHCSHA0E January 2018 – March 2021 DRV10974
PRODUCTION DATA
Every time the DRV10974 device exits low-power mode, it determines if the motor is spinning using a function called initial speed detect. If the frequency on the FG pin is less than 10 Hz, the motor is considered stationary. If the frequency is greater than 10 Hz the motor is decelerated until it is below 10 Hz or a 5-second time-out has occurred.
