TMC 188/40 Motion Control Module Hydraulic System Problems
If the speeds show:
Your valve is probably curvilinear. Replace the valve with a linear one or increase the static gain and
tune the system for high-speed stability; expect poor control at low speed and when stopped.

add differential gain (usually less than 5).
