After it is determined that the motor is stationary and after completing the motor initialization with either align or IPD, the DRV10982-Q1 device begins to accelerate the motor. This acceleration is accomplished by applying a voltage determined by the open-loop current setting (OpenLCurr[1:0]) to the appropriate drive state and by increasing the rate of commutation without regard to the real position of the motor (referred to as open-loop operation). The function of the open-loop operation is to drive the motor to a minimum speed so that the motor generates sufficient BEMF to allow the commutation control logic to accurately drive the motor.

Table 8-5 lists the configuration options that can be set in register to optimize the initial motor acceleration stage for different applications.
