This is what is written in the troubleshooting guide: During Autotune the motor is required to run at the nameplate speed of the motor. If MAX SPEED RPM limits the speed to less than this value, an error will be reported.

Increase the value of MAX SPEED RPM up to the nameplate rpm of the motor (as a minimum). It may be reduced, if required, after the Autotune is complete.

It looks like the max RPM calibration value may be the source of this fault. You'll have to verify that you've got the right value for this setting.
