Additional Setup for Closed Loop PM Motor
After performing an autotune on an closed loop PM motor, a PM angle
alignment needs to be performed to complete the setup.
Align the PM Angle
To align the PM angle, do the following:
1. Uncouple the load.
2. Set these parameters to the recommended value:
•A517 [PM DC Inject Cur] = 60% (default is 30%)
• A518 [PM Align Time] = 5.8 s (default is 0.7 s)
• A580 [Current Loop BW] = 300 Hz (default is 0 Hz)
3. Set the desired speed (10...40 Hz recommended).
Check the setting for P047 [Speed Reference 1]. Speed reference can be
from POT, control panel of Connected Components Workbench
software, and so on.
4. Set the Start Source.
Check the setting for P046 [Start Source 1]. Start source can be from POT,
control panel of Connected Components Workbench software, and so
on.
5. Start the drive to run at the desired speed.
6. Drive will begin to align itself (move forward and reverse) and run to the
desired speed.
7. Stop the drive. The drive is now aligned.
Adjustments if PM Angle Alignment has Failed
If the PM angle alignment has failed, do the following:
1. Cycle drive power or set A535 [Motor Fdbk Type] = 0 “None”, then set back
to 4 “Quadrature” or 5 “Quad Check”.
2. Increase A517 [PM DC Inject Cur] by 50%.
3. Increase A518 [PM Align Time] by 0.2 s.
4. Repeat the Align the PM Angle
instructions again, beginning from step 3.
The PM angle alignment only needs to be performed once unless the drive
is power cycled or re-tuned.
IMPORTANT
The PM angle alignment has failed when fault F012 (HW Overcurrent) or
F013 (Ground Fault) is observed during acceleration and deceleration.
