MCSDK 5.4.3/5.4.4. Sometimes after encoder alignment ,motor run reverse。

Hi!

I have a I-PMSM motor and interfaces a incremental encoder with A B ,without Z.

Sometimes after doing encoder alignment,the motor runs reverse to the max speed,and it will never recover until i do encoder alignment again。

I set the speed 30RPM,but when start ,the motor goes to -200+RPM.

Most time the motor runs well but sometimes the problem will happen.

(STM32 F303VCT6 ;PWM16000KHZ ;Main Sensor :Incremental Encoder2048 no Z-index)

I hope someone could help me figure out the problem.

Best wishes.

The question has been moved from the "Motor Control Hardware" section to the "STM32 Motor Control" section (the question is about the STM32 MC SDK). 

Best regards
