GE Industrial Solutions AF-650 GP General Purpose Drive (460_575_690V 125HP and above) - Manual (Page 80)

NB!
It is important to set motor par. F-04, F-05, and P-02 to P-08 correctly, since these form part of the Auto Tune algorithm. An Auto Tune should be performed to
achieve optimum dynamic motor performance. It may take up to 10 min, depending on the power rating of the motor.
NB!
Avoid generating external torque during Auto Tune.
NB!
If one of the settings in par. F-04, F-05, or P-02 to P-08 is changed, par. P-30 Stator Resistance (Rs) to par. P-01 Motor Poles, the advanced motor parameters,
will return to default setting.
NB!
Auto Tune will work problem-free on 1 motor size down, typically work on 2 motor sizes down, rarely work on 3 sizes down and never work on 4 sizes down.
Please keep in mind that the accuracy of the measured motor data will be poorer when you operate on motors smaller than nominal drive size.
