2 Spinning the motor

This section provides standardized steps to tune the MCF8329HS's settings so that the motor can successfully spin-up and enter closed loop control.

The general steps to tune the MCF8329HS's registers so the motor can spin-up and enter closed loop control are outlined in Figure 2-1
