Responce From Estimated SysID Modell in Simulink isn't the same as shown in matlab compare() function

I have recorded requested motor torque data and current position data.
Split them. From the first half of the data created iddata object EstimationData. From the second half ValidationData. Then run:
processModel=procest(EstimationData,'P3DZU');
then run:
compare(ValidationData,processModel);
shows following response with very good fit of 99,54 %.
Then following Sinulink structure is build:
Scope shows following picture:
So my question is, why doesn't the signals match ob Scope how they match in the figure after calling compare function()?

Hi Iaroslav,
The possible reason might be the simulation parameters, also try adjusting initial conditions of simulink model to match that of validation data.
