Parker AC30 series User Manual

Parameter Reference C-149
AC30 series Variable Speed Drive
In the case of a wrong 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 13 14 15 16 17 18
States
210°
-30°
90°
From State 4 to 9, a wrong direction as been detected, and the direction should be reverted. Alignment Direction is set to REVERSE.
During the final state ( 17 ), the Alignment Offset is automatically calculated and is passed back to 1808 PMAC Encoder Offset
Also 1809 PMAC Wiring is set to REVERSE.
In that case, the direction of motor rotation has been changed during the Pos Alignment sequence. Please verify if the new direction is
compatible with your application.
If you want to change it, please change the Invert parameter of the active encoder used to control the motor and run again the Pos
alignment sequence.
Drive settings during Pos Algnment :
Some errors may occur during the Alignment sequence which are related to the setting of the drive. Please be aware of the following
- It’s better to run it with a speed setpoint at 0% ( Speed Error could end up the sequence before end )
- When running Alignment Method = DIRECTION TEST, either set 1257 Seq Stop Method to DISABLE VOLTAGE or 0505
Zero Speed Threshold to 1%
- When a resolver is used, the filter on the speed should be left at default values or set to good known values.
