And that would be perfectly acceptable in my application too, thinking about it, though I like the idea of being able to power up the servo drives independent of the main contactor, just so that I can delay it until the VFD has come up. I think that I will also look into using this as the main contactor, as it is cheap and I can buy it on the way home: http://www.maplin.co.uk/p/30a-spdt-power-relay-24vdc-n25aw -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1916 ------------------------------------------------------------------------------ Find and fix application performance issues faster with Applications Manager Applications Manager provides deep performance insights into multiple tiers of your business applications.
