Hello. 

Can anybody give me an idea what could be the problem of my Base oil pump drive.

We have a problem. Please see summary.

***********************************************************

6.Replaced CuVC card with new one ( 6SE7090-0XX84-0AB0 ). Same part no. of old one.

7. Replaced its CBP2 card ( 6SE7090-0XX84-0FF5 ) 

8. Replace IVI card ( 6SE7038-6GL84-1BG0 )

9. Measured values using masterdrive test box and it seems that all values are good. Power supply , Current sensors value , Transistors etc.

The main problem now is that the VFD is not communicating to El.motor and IAS. 

Can you please help.
