Motor ID Run

Autophasing
The drive is now ready to run the motor identification
routine (ID run). During the ID run, the motor is
injected with DC current. Autophase stops the rotor
prior to the ID run.
Note: Autophase time has a default of 15 seconds.
It is best to observe the time it takes the fan to stop
moving and use this as an accurate autophase time.
Use the keys to move between selections.
