If that Nano pin can be a PWM output it could be done in the firmware. That is true with some caveats. When the Nano was first proposed to be used we only wanted it to run the inverter and not take its eye off the ball lest there be grief. Since then Poida & KeepIS have included bells and whistles galore. It is a credit to their programming skills that grief has not visited the Nano inverter so far. Depending on the supply voltage if a Kilovac is to hand or used at all with or without economiser. The ensuing software becomes more complex with a need to alter as required. I chose to not go down that path despite some on the forum who are able to do this I chose the Kiss principle of a dedicated drive to the correct voltage Kilovac with or without economiser. The system is there and I agree if someone wants to write code for pull in and hold be my guest but obviously all at your accepted risk.
