Has anyone set up a simple hourmeter for scheduled maintenance?

Hi,

Sauer-Danfoss has!  You'll need to download the inverter function block library and you'll find one in there accurate to 0.001 hour.

Did anyone come up with a solution for power downs?  The Plus+1 doc's say there is a 1M limit on memory writes so saving every minute is only good for 2 years.

I monitor the supply voltage and store the minutes only, as soon as the voltage goes below 23 or 11 volts. Until now, this was for my applications always good enough.
