Ok, I missed a digit in the number. That's why you didnt get it.

Two questions.

1. Inverters / VFDs.

I was sent two in error for the 4KW Chinese spindle. One is a 220V input, the other 380V. My logic says that I can use either with a 220V input (single phase) and that the 380V could later be used if I had a 3 phase 380V supply (different motor).

The supplier indicates that the 380V one (with a 220V input) will damage the 220V spindle.

Thoughts?

2. I am looking to use NPN proximity switches for home locations. Easy.

The CS Labs IPA unit document shows an example where normal switches are used where home and -- (limit) is the same switch and then ++ (limit) is a different switch.

Is this commonly done? I was under the impression that there are only very limited inputs that Mach 3 will accept as limits (from 9 to 13 from memory).

Thanks
