For the connection to the VFD run a wire from the center screw terminal on the run relay to the common pin 11 on the VFD. Then run a wire from NC screw terminal on the Dir relay to terminal 1 on the VFD. Then run a wire from the NO screw terminal on the Dir relay to terminal 2 on the VFD.
To me, unless you have a Stop connection the VFD will always be in run?
Unless we are not getting the full picture on the VFD?
The contact is labelled RUN/Stop which implies that you open it to stop?
