Replace Matlab FCN with Stateflow Chart - Error

Hi Guys,

i replaced a working matlab fcn with a stateflow chart. To be honest i didnt expected any errors because it is very simple.

The Model looks like this:

This is the Matlab fcn:

function [w_r,theta_r,iq_ref,motor_state] = fcn(ramp_endspeed,w_r_ramp,theta_r_ramp,w_r_foc,theta_r_foc,Iq_ref_foc,Iq_ramp,pre_motor_state)

if pre_motor_state == 1
    w_e = w_e_ramp;
    theta_e = theta_e_ramp;
    Iq_ref = Iq_ramp;
    if w_e_ramp >= ramp_endspeed
        motor_state = 2;
    else
        motor_state = 1;
    end

elseif pre_motor_state == 2
    w_e = w_e_foc;
    theta_e = theta_e_foc;
    Iq_ref = Iq_ref_foc;
    motor_state = 2;
else
    w_e = 0;
    theta_e = 0;
    Iq_ref = 0; 
    motor_state = 1; 
end

and then i build the statflow with the "classic" setting. But Simulink recommended me to use the "moore" setting.

So this is how it looks like:

in classic like this:

But the moore stateflow generates this error:

And im not understanding it.

Maby this input and output definitions could help u to understand my problem:

Inputs and outputs are the same in the Matlab fcn and stateflow. and the logic should be the same.

Thanks in advance.

Best regards
