Please post a copy of the drive parameters for review. 

I see in a previous post you are asking about running a motor that is rated much higher than your drive rating. The parameters you uploaded reflect this also. First thing I would say is that the motor and drive should be sized correctly. You may be able to get this setup working however its definitely not a good way to operate. Some questions/comments;

• Was this drive running previously with a correctly sized motor?
• The drive parameters dont look correct for output voltage and current.
• The input and output attenuator sums along with CT turns need verifying against the drawings. 
• I would put flux control, speed loop and current loop parameters back to factory defaults. These parameters dont typically require changing for a centrifugal pump application. 
• Use a correctly sized motor/drive combination and you wont have any issues.
