Appendix J PowerFlex 525 PM Motor Configuration
Direction Test
Perform a Direction Test. The direction test can be performed with or without
the load attached. Consider your application requirements when deciding to
have the load attached or removed from the motor. This test runs in V/Hz
mode to verify the motor polarity relative to the feedback polarity. The test
confirms motor rotation and feedback polarity. After the test is completed, a
change can be made, if necessary.
Auto Tune
Ensure the load is uncoupled and perform a Rotate Tune test.
Run the drive with P040 [Autotune] = 2 “Rotate Tune” configured to
complete the autotune process. This process measures and configures
the following:
•A501 [PM IR Voltage]
• A502 [PM IXd Voltage]
• A503 [PM IXq Voltage]
•A504 [PM BEMF Voltage]
The Auto Tune is used to identify the correct motor flux and stator electrical
properties, including the following:
• IR volt drop, which is voltage drop over resistance.
• IXd volt drop, which is voltage drop over inductance.
IMPORTANT
When configuring a PM motor or using an encoder, it is required to perform
a Direction Test before proceeding to the next step (Auto Tune).
IMPORTANT
If the drive was never operated before (new installation), verify that
safeguards are in place to remove power safely from the drive during an
unstable situation where the drive can produce undesired motion.
