Does anyone have any knowledge on these units? It is an AC drive Digital Speed Controller. The issue I am having with this unit is no 0-10vdc output from terminal TB3. If you have seen these units and know anything please help!
I thought that was my problem as well but changed every diode on the board. Also changed the PNP and NPN Transistors, Voltage Regulator, caps and Op Amp chips. I have three units doing the same thing and still no output from either? not sure what else to do with these units... Thank you for your input tho!!! Kinda surprised someone actually knew what I was working on!! If you have anymore tips or can maybe get me in the right direction it would be greatly appreciated!!
