Hi.

I have configured the basic project in MotorControl Workbench for 36V BLDC with integrated HAL sensors, but when I try to start it the motor ripples for a moment and than I have a speed fault. In workbench integrated monitor I can see that speed changes when I rotate the motor manualy, so I have no idea what am I doing wrong. Where should I search the problem?

I have found the problem on my own. Developers installed 10pF capacitors in HAL RC filters which makes it nearly useless. So I replaced capacitors to 100nF and now it works stable. 0690X00000Bwn5oQAB.png
