    Gents,

    Thank you for your help. I will do as advised - will use relays to control CW and CCW of spindle. I have ordered relay set from link provided by Lee Roberts. Will try and come back with results :)

    One more idea I have, and I will risk to share it . UC300 have 2 analog outputs and those are without opto-isolator. Would this be a solution ? Or should I stick with opto-isolated outputs / relay confirguration ?


    Another question I have regarding stopping spindle if e-stop is activated. At the testing VFD /spindle I had an issue that when UC300 gives message on screen that it has been disconnected - spindle is up and running anyway... I want to avoid that in the future.     VFD has 2 relays that I could use for this purpose. Please see attached pic of the wiring I think to go with. I see that relays are 24v operated, can I use internal VFD +24V supply to drive the relays ?
