Good day,

I have a problem with my Fadal 4020 mod 98, RPM not see on the monitor when working a program, I can regularly with the potentiometer, but I do not see the real value on the monitor.

Inspecting the control panel, found a 10-pin male connector loose, and a blue 10-pin female connector on the motherboard 1010-5d. Apparently they should be united. belongs to the male connector to motor encoder?

Thank you for your attention.
