That looks quite useful to me. One feature that isn't mentioned is that if the solid-state-relay is of the zero-crossing type then powering the VFD and/or its input filter through that relay will prevent problems with RCD (US GFI) breakers in the supply circuit. Currently I have to plot my route out of the garage before turning on the new milling machine VFD because 9 times out of 10 doing so turns out the lights :-) (I already have an SSR to solve this, but at the moment I just have things thrown together so that the mill can be used manually for drilling etc.) -- atp "Torque wrenches are for the obedience of fools and the guidance of wise men" ------------------------------------------------------------------------------ Free Software Download: Index, Search & Analyze Logs and other IT data in Real-Time with Splunk.
