G120 Encoder Problem

Hello Experts,

I have a question about a CU250-2PN in which I am using 1024 PPR incremental encoder  type.

When I am Running in V/F mode my encoder values are showing same as the speed i am giving setpoint. but this value is not continious, i.e this value is some time showing and some time not showing.

When running in Vector mode immediately fault comming like Speed ouside tolereance value.

checked running in SLVC mode encoder value do not recieving in r61.

what could be the problem.

thanks in advance
