We are using Siemens Sinamics S120 with sensorless vector control for motor. One motor speed is showing always overspeed. and if i trace actual speed and speed reference i saw wild fluctuating in actual speed. For this motor it is used torque control and it is getting torque setpoint from another motor, this motor is configured as speed control and working fine.
My question is how to tune this torque control motor. Because if i change this P & I value of speed controller of this motor it does not change anything. Then where is P & I value of this motor, so that i can tune ?
Thank.
