2.1 Minimizing Motor Startup Time

In this application note, startup time is defined as the time taken for the motor to enter closed loop from a stationary position. The MCF8316A provides four different motor startup methods as listed below:

  • Align
  • Double align
  • Initial Position detect (IPD)
  • Slow first cycle

Double align is not discussed in this application note as this method takes the maximum time to start up the motor.
