SIMODRIVE 611U and 1FK7042-5AF21-1TA0 (Enter data)

Hi,
We have 611U - (6SN1123-1AB00-OHA1 + 6SN1118-0NK01-0AA1) and motor 1FK7042-5AF71-1TA0, motor damaged, we have another motor 1FK7042-5AF21-1TA0,
we need to use (at least temporarily) this motor!
I understand that this motor is not compatible with Simodrive 611U (motor 230V),
but yet another motor we do not have.
but we can try to enter the motor data
menu ->Motor selection->Motor-Enter data...
Earlier we already did and it worked well,
problem did the other person, which is now is not with us,
could you tell what kind of parameters I can try to change?
for example, how to say Simodrive 611U it uses the motor 230V?

technical support said...

the Simodrive 611USystem is only for 600V, therfore you have to change the Motor.

, but I think that we can try... (we have no other choice)
