Hullo neighbors,
We've got a LOGO! 0BA8 configured to use I8 as an analog input,
and the goal is to read the current operating speed of an ABB ACS310 VFD.
(we want our PLC to be able to react to any changes in speed from the VFD)
Problem is, nobody can figure out how to hook up the analog output from the VFD to the analog input on the PLC.
Have tried going from AO -> I8 and have also tried adding a connection from the LOGO! input neutral back to the GND... nothing works.
Attached is the terminal diagram for both devices with our poor attempts labeled.
Any insights?
