PRODUCTION DATA
Slow First Cycle start-up is enabled by configuring MTR_STARTUP to 11b. In slow first cycle start-up, the MCT8316A-Q1 starts motor commutation at a frequency defined by SLOW_FIRST_CYCLE_FREQ. The frequency configured is used only for first cycle, and then the motor commutation follows acceleration profile configured by open loop acceleration coefficients A1 and A2. The slow first cycle frequency has to be configured to be slow enough to allow motor to synchronize with the commutation sequence. This mode is useful when fast startup is desired as it significantly reduces the align time.
