Hi,

Looking for some guidance, and input i guess. I have a 1.8kw servo motor and matched drive from DMM, For those of you that have the same setup, ive seen a few mention they have this drive running at 2:1 to achieve 6000rpm, have you had any phase fault issues?

I cannot get past 2600rpm in the DMM software. It just goes to phase fault, while machining any minor load on the motor and it also shuts off. These were cuts my treadmill motor was making with ease at 4300 rpm.

This is running on a G0704 mill with a 1.7:1 ratio. I guess this is somewhat irrelevant due the motor not being able to reach max rpm even during bench testing.

I have been in contact with DMM and in turn they are in contact with their development team.

But id thought id ask here as im sure there are quiet a few people with these motors/drive setup on here that i could compare notes with.

Cheers Daniel
