STM3240G EVAL + STEVAL-IHM023V3 didn't work.

Hi everyone.

I want to control PMSM using STM3240G and STEVAL-IHM023V3 power board. When I test with Motor Profile Tool, motor working correctly. But when I use Motor Work Bench to generate code and down upto STM3240G, motor didn't work. It's seem like there is no pulse from STM3240G to power board because I do not see the fuse close at first.

Please help me solve problem.

Sorry I'm late. Now motor work well. But I just meet a new problem. When I set a high rpm, motor run well but when I set a low rpm, like 100, 200 ... motor didn't work. When I push start button, motor just spin a very little angle and stop. I think this problem caused by PI speed control and modified Kp or Ki but the motor still work.

Please help me solve this issue. Thank so much.

Plus, I use STM3240G EVAL and STEVAL-IHM023V3.
