TPDO and motor control conflict on B-G431B-ESC1

[Jan57555]

Hi. I have a B-G431B-ESC1 and use it do drive a motor.

Now I have the following problem: when I use TPDOs, a FOC Duration Error gets triggered as soon as the MC_StartMotor1() function gets called.

I believe it has something to do with the canopen_app_interrupt() function. When deleting the canopen_app_interrupt(), no motor drive errors get triggered. But then of course TPDOs wont work anymore.

Is there a reason for this behaviour? Are these functions in conflict with each other?

Thanks for your help!

Hi, you can try to reduce the the frequency of interrupt and see what happens. you might lose time accuracy on TPDO transmission.
