text: <s>[INST] PowerFlex DC Configuration I have a 150HP Powerflex DC drive configured to run a DC motor with Armatuer Current of 242Amp, 400V, 1150rpm, my Field Resistance is 25 Ohm and Armatuer resistance of 0.5 Ohm., When I do the Autotune it coz some fault unknown error what did I miss? [/INST] First before you Autotune the drive make sure the motor is uncoupled from the load as it has to be free to rotate. Also, what is the firmware of your DC drive? \\n </s>
