C-148 Parameter Reference
AC30 series Variable Speed Drive
Alignment Method = DIRECTION TEST
The motor is slowly rotates with the following sequence U, V, W, U, V, W…..
It allows to verify the rotation direction and detect any wiring inversion on the motor phases.
Active encoder Invert parameter has no effect during this test.
Looking at the position form the active encoder may help to know if the active encoder is correctly wired.
Considering a correct connection of the motor phases :
When running this Method, either set 1257 Seq Stop Method to DISABLE VOLTAGE or 0505 Zero Speed Threshold to 1%otherwise you may end
up with a motor rotating at slow speed for 60s without any possibility to stop it.
Alignment Method = AUTOMATIC
In case of a correct wiring of encoder and/or motor phases, the sequence is as follows :
Current
%
Elec pos
1 2 3 4 5 6 7 8 9 10 11 12
States
210°
-30°
90°
During the final state ( 11 ) , the Alignment Offset is automatically calculated and is passed back to 1808 PMAC Encoder Offset
Also 1809 PMAC Wiring is set to STANDARD
