Keep adjusting the Field Weakening Drive value and repeating the test until you nd the
Field Weakening Drive value that results in the smallest Time Between Speeds. Use this Field
Weakening Drive value for applications that require the most torque at high speeds.
Some Field Weakening Drive settings may result in a test acceleration run where the Capture
Speed 2 cannot be obtained. ese Field Weakening Drive settings cannot provide enough
torque to get the vehicle past Capture Speed 2, and thus can be ignored.
Use the Field Weakening Drive setting that best matches the application. It will be somewhere
between 0% (most ecient, least motor heating) and the setting found in this test (highest
torque at high speeds).
Note: The Field Weakening Drive setting will have no effect at motor speeds below FW
Base Speed.
AUTOMATED PMAC (MOTOR) COMMISSIONING PROCEDURE
When commissioning PMAC motors, the parameters cannot be copied across from EOS to FOS for
PMAC. Use these instructions for the present commissioning process for PMAC motors. e default
cdev (FOS 4.0) will show the Motor Setup Needed fault will be present. is fault must be cleared to
allow motor operation by following the below PMAC commission procedures.
e Motor Setup Needed fault Type will indicate the tests that need to be run. Bit positions are:
Bit Positions Description
1 Current regulator tuning.
4 Full automated test run.
Prior to performing the commissioning routine, set up and save this controller/motor as a CIT project.
Save the project: CIT» Launchpad » Project tab/ Save As… option.
Be sure to navigate to a dened le folder location to save this “.cprj” le.
The motor will rotate during this procedure. Do not take the vehicle down off the blocks.
