Type mismatch for equation

Error compiling Simscape network for model RobotAssembly.
Caused by:
['RobotAssembly/PS Integrator']: Type mismatch for equation.  The left hand side of the equation is {[1x1 double], '1/s'} and the right hand side of the equation is [1x1 double]. In foundation.signal.linear.integrator (line 59)
x = [1x1 double] 
I = [1x1 double] 
Component: Simulink | Category: Model error

And the code in integrator.ssc file is as below:

% PS Integrator :0.75 :fixed
% This block performs continuous-time integration of the input Physical Signal.
% The output resets to the initial condition when the optional reset signal, R,
% triggers. The initial condition can be a fixed parameter or defined via
% physical signal, X0.

I used smimport(xml file) from solidwork and add PS Constant and PS Integrator to rotate wheel but error

把ps积分器中的单位改为rad
