Powerflex 70 - Unable to complete a P69 Autotune

Hi.  Currently, using the Powerflex 70, we are trying to perform a P69 Autotune & get a '79 Excessive Load' fault.  However we are not attached to the load.  Does anyone have suggestions or experience with what we may be missing?

 

Thank you.

Double-check the motor nameplate data including the number of poles.  Most people assume a 4-pole motor.  What motor is the motor data and is the drive uncoupled from any gearbox that may be there?
