Set Up PMAC Motor Control – Pos Alignment after Power-up
Vector Control of a PMAC motor needs to know the relative position between the rotor and the stator.
Pos Alignment sequence allows to synchronise encoder position to Motor Back EMF.
This feature is used to automatically calculate any offset between the encoder absolute position and the motor back EMF, as well as selecting the
correct wiring of the motor ( U, V, W sequence ) with the encoder position.
The feature needs to be run after each power cycle with a PMAC motor associated to a non absolute encoder type ( pulse encoder )
The feature is run on a motor free of rotation, no load attached to the motor shaft.
Depending of the Alignment Method selected, the motor is moving during the sequence.
Below is a simple example on how to force the system to run a Pos Alignment sequence on the first start after power_up :
Alignment Method is set to Manual ( It could have been set to AUTOMATIC ).
Alignment Enable is TRUE from Start-up.
The first start command will run the Pos Alignment sequence.
A running and successfully sequence resets Alignment_Enable to FALSE.
A 1s negative pulse is generated at the end of the sequence. This information can be used to toggle any command to start the system.
