Hi,

I am using lab12b for controlling a motor with an encoder. The motor spins which confirms the encoder lines and wiring, however, the Iq current increases gradually and the motor stops. The iq increases quickly when the speed is higher. I tried to manipulate the current controller gains (Kp, Ki) but the behavior is still the same.

What can be the possible reasons for such a behavior?
