Ctrlx drive sincos relative encoder on XG21

I connect the sincos encoder to the XG21 multi encoder connector. 

I use encoder ITD 49H00 0064 M  of baumer and mechanic connected to the motor shaft. 

this is an Sincos encoder 1Vpp with 64 period per revolution. 

so i configur this as encoder 1 see picture below: 

When i move the motor shaft i see the value basic output data changing but i do not see the value actual position value at extended output data changing. 

Also i can home the encoder by SET absolute position. 

then i get the message:

What could be the problem?
