I have opted for an other approach and designed a simple inverted Schmitt-Trigger to convert the existing 0-10V output to Spindle Enable for SuperPID.
It takes the 0-10V from X-Controller and 5V/GND as input. The output will be 0V if signal reaches ~0,88V and back to 5V if signal falls below ~0,66V. Due to design the output never goes over 5V.
The whole project for KiCad with layout can be found here:

Hey @OliverDorn - that circuit is flippin great! Exactly what I needed and works a treat. I had started with a comparator design but then realized I had a problem with hysteresis (or, more specifically, not having any). I hadn’t known about Schmitt triggers and this is just the ticket.
