Like many people I run some machines on inveters - partly for 3 phase conversion but also for speed variation. Being a tidy person I've tucked the inverters away inside the machine cabinets. Is there a way to have the inverter frequency output displayed so that I can at least mentally calculate "50% of rated speed" or similar. The ideal would be a display that could be mounted somewhere visible.
Suggestions welcomed, simple and more complex!
