Sorry for the late reply - I responded to this post earlier, but didn't notice that it was going to John only. Here my response again to the mailing list:

Yes, I really only changed the frequency.

However, you were exactly right with your assumption that the simulation timestamp was too long. I chose (shame on me) 0.01 seconds which yields a maximum sensible signal frequency of 50 Hz. That the 4,7 kHz worked was probably just some aliasing effect.

Thanks for the pointer...

Kind regards,
