TPS Compact pump show fail message with error code 128: TOO HIHGT LOAD and prevents the turbo pump from turning on.

Hi. The pump made loud noises for several days. After that, the pump stopped working normally. Near 600 rpm the pump stops and A-PLUS Software was showing fail status (205) with error code 206 (bit 128) - too hight load.
We use Agilent pump - TPS compact (model 9698227) made in 2011. I have additionally attached a Debug Event List File.diagnostic.xls 
I have a few questions:
1) What can this error be related to?
2) How to fix it?
3) If it is a mechanical breakdown that requires replacing a spare part, are there Agilent service centers in Ukraine to do it? Or advise companies that could do it?
4) Is there additional software for pump diagnostics (besides A-PLUS Software)?
Thank you very much for your answers and advice.
