Torque limitation in PMSM FOC

Hi,

I'm controlling my PMSM at zero speed. While I'm trying to move its shaft I don't want my motor to generate its maximum torque to resist my movement but the limited one.

Everything went fine with classic control, but as soon as I tried to limit it's torque -- by limiting outputs of speed and Q-current PI controllers on some smaller values -- the motor started spinning (?!). 

I really have no idea how to accomplish described task, exept by limiting outputs of PI controlers 

Any suggestions?

Thanks in advance!
