Hi guys,

How can i solve the problem that motor vibration in zero speed? i'm using G431B board T-MOTOR 2312 and hall sensor(120 degree), set to torque mode, the motor work fine most time, but it will be vibration when start-up with heavy load or i stop the motor with my hand. 

Is that normal? i did not see this problem in other foc drivers like VESC​ or odrive.

​

Really appreciated for any help.
