I have 2 DC drives 6RA2471-2FV62, I used them for 440VAC with a dc motor of 92A 440vac 2.6A of field, they work excelent for 440VAC but I change my place and I need configurate them for 220VAC, I configure the transformer for 220VAC and when I try to set the autotunning (p051 - 25) it fail (F050 word 7) so I suspect of the motor so I reconfigured for 440vac (apply 440vac to drive) and then I configure it and it's works fine, (pass all the autotunning) but the motor is 220vac so I only apply a very low reference to prevent a excesive voltaje output.

My question is, Are other configuration that I need to change? or is a parameter configuration problem?

thank you

Yes I changed the motor from 440vdc to 220vdc motor, the new thing I discovered is when I used the 220vdc motor with the drive configureted to 440vdc it works perfectly it pass the autotune, just I don't increase the output voltaje beyond 220vdc caus it could give more than 440vdc, but when I try to set the same 220vdc motor with a 220vdc drive configuration it fail the autotune (P051-25)

and for the other question yes P047 word 1 - 7

I try setup the drive manualy and it's working but not like it suppose to does, it only give me an output of 120vdc

thank you
