Most VFDs can be programmed for F/R mode. If this feature is not available with your inverter the 7I76 will need an external SPDT relay or SSR, I intend to add this feature on the next 7I76 version but its not available yet. Wiring (for ground to activate) is ENA- --> Ground ENA+ --> Relay COM DIR+ --> +24V DIR- --> Relay coil Relay NC --> Inverter F Relay NO --> Inverter R If the inverter F/R inputs can be driven with field outputs, (that is, they can be actuated by +12 or +24V signals) you can use those instead of the spindle control outputs http://www.vishay.com/solid-state-relays/list/product-83812/ Are nice SPDT SSRs for these types of applications > > -- > > Regards /Groete > > Marius D.
