I have attached a copy of the breakout board I am using together with extracts from the VFD manual (some pages need to be rotated sorry.
Spindle and VFD are connected via a three pin plug (No Earth) the combination was purchased on Ebay. I wish to connect the VFD unit to the computer and control activity through Mach3.
The unit works fine via the control panel but trying to sort out which Control ports to connect to the breakout board and indeed which ports on the board to connect to so that control is through Mach3 are deleting already grey hair from my head.
My fault I thought I was ok buying the HY series however this is not the traditional version with 3 hot wires and 1 earth connecting VFD and spindle NO as i mentioned earlier just 3 hot wires. No earth and Control ports are reduced to one line of 16
suggestions would be appreciated
