Please read earlier reply from KSN. KSN Hello. When you are using field weakening mode you always need speed feedback from encoder or tacho.

I don't see in your parameter list that field-weakening was enabled (P081=1). hi sir, in the old driver p081=0, in my list i attachment, that's the parameters have changed for the default parameters.i see some parameter is set automatically during the field-weakening optimization run (P051=27) sush as: p117 p118 p119 so when i upgrad to 6RA80 i need to choose a p50051=27 or not? because motor have no encoder or tacho

Another case these parameters may be have been copied from another drive while copy complete parameters backup. Also may be your drive previously worked in field weakening, but then this mode was switched off. Check your motor nameplate, does it support speed above rated. Check your application, do you need field weakening (or speeds above rated) or not.
