Torque control - speed feedback error

Dear Support team,

I am currently working on a NucleoF302R8 and IHM07M1 driver to run a 24V PMSM motor (rated at 3600 RPM, no load).

I'm using STM32 Motor Control Workbench version 6.4.0. Whenever I attempt torque control, I consistently encounter a speed feedback failure. I've tried lowering the C2 Leuenberger constant, but the issue persists. Interestingly, this problem doesn't occur in speed control mode—everything functions correctly when running in speed control.

I would appreciate your assistance in understanding and resolving this issue.
