7.3.9 Starting the Motor Under Different Initial Conditions
The motor can be in one of three states when MCF8316C-Q1 begins the start-up process. The motor may be stationary, spinning in the forward direction, or spinning in the reverse direction. The MCF8316C-Q1 includes a number of features to allow for reliable motor start-up under all of these conditions. Figure 7-21 shows the motor start-up flow for each of the three initial motor states.
Figure 7-21 Starting the motor under different initial conditionsNote: "Forward" means "spinning in the same
direction as the commanded direction", and "Reverse" means "spinning in the opposite
direction as the commanded direction".
