Parameter Name No. Path Default Range Units Writable
Set to TRUE, this parameter automatically trips the drive after a power up on a Start command until an Alignment sequence is run and
completed successfully.
This is useful when the PMAC motor is associated to a relative encoder type and the position synchronism between encoder and motor
is lost due to power off.

Each Method is extensively described in the Functionnal Description .
MANUAL :
allows to place the motor in the selected position defined by the parameter “Alignment On Motor”. This method should be selected for multi
poles resolver with non integer value.
AUTOMATIC :
Sequence runs automatically by the drive, on a start command from the user.
Allows to set up correctly the ‘encoder/resolver’ and the motor by :
-
Changing the motor phase connection of phase V and W internally to the drive if a mismatch is found between ‘encoder/resolver’
positive direction and positive motor electrical position
-
Automatically calculate the offset of position to align zero ‘encoder/resolver’ to U motor phase.
DIRECTION TEST :
Allows to verify the direction of positive electrical position by slowly rotating the motor. A correct wiring of the motor phases should turn the
motor in a clockwise direction looking at the front shaft of the motor
