Other Parts Discussed in Thread: LAUNCHXL-F2800137, BOOSTXL-DRV8323RH
Tool/software:
Im using LAUNCHXL-F2800137 + BOOSTXL-DRV8323RH and trying out Universal Motor Control Lab Level 1~4.
Level 1 was successfully built, and I confirmed that the variables in the expressions appeared as described in the manual.
However, while testing Level 2, I encountered a moduleOverCurrent error, with motorVars_M1.faultMtrUse.all showing a value of 16.
I referred to previous forum posts and attempted to adjust the motor parameters. Unfortunately, the datasheet for the motor I am using -Alien Power System APS 5055S Sensed Outrunner Brushless Motor 220KV 1600W—only provides the limited information shown below.
I tried various adjustments to run the motor in Level 2, but the moduleOverCurrent fault continues to occur. Therefore, I would like to ask if you could provide guidance on the appropriate parameter values for this motor.
Additionally, I have reviewed Appendix A. Motor Control Parameters in the Motor Control SDK Guide, but I am unsure which variables I should primarily adjust. I would greatly appreciate any advice you could offer.
Currently, the parameters in user_mtr1.hare defined as follows:
