1500MX not going above 4300 RPM -- overrides not adjustable

Mill

using S10000 M3 in the MDI console only spins the spindle up to 4300 rpm, and the S and M overrides are stuck at 62 and 43% respectively. No reset to 100 button or any ability to adjust them. Tried in run and setup modes, no change. M48/M49 similarly do nothing

Anyone have a solution for this? I’ve read over most of the manual at this point and I can’t find a cause

What happens when you turn the override knobs on the front of the control?

nothing

I recently had to replace the op-console, lemme open it up and check the connections

I swapped the potentiometer board in from the old op console and that seems to have restored functionality, thanks for the tip
