How to use a speed limiter with a square signal and a variable step size in Simulink?

Here is a screenshot of the model I would like to customize:

model :

I feed the tuned square wave to the speed limiter to avoid vertical slopes.

Unfortunately this does not work. I use ode15s , this is a requirement. Here the Simulink error message throws:

Error: The input signals to the '... / Rate Limiter' speed limiter are neither discrete or continuous sampling time signals. Discrete only or continuous input supported

Quite unexpectedly, I found workaroud, adding an integrator directly, and then a derivative. It works:
