1kW servo as spindle. Steps overflow HELP!
« on: June 07, 2019, 04:32:48 PM »
Hi all!

Has anyone tried this?

I've monted this in an Emco VMC-100, and it's working great! As long as I'm controlling this with 0-10V input, but wanted to try to use STEP/DIR as this is a possiblilty both in Mach 4 and in the servo, my goal is to do rigid tapping :) and with this method I'm able to go both CW and CCW.

But after a whole lot of setup and connections I finaly got it running CW/CCW!
But if I run it with M3/4 and finnish off with M5 after a while I get a warning+e-stop and the message "Motion steps overflow (-some number) check motor speed parameters"
the number in (-some number) is:
RPM=1000, some number=271
RPM=1000, some number=543( seems to double...)

anyone have encountered this?
