General Mach Discussion / Mach 3 random EMO after installing new motor and VFD.
« on: April 23, 2020, 12:43:42 AM »
Hi all, Can anyone tell me how Mach 3 generates an EMO signal? My mill has been running for years but I just upgraded the motor and now it just randomly goes into alarm for EMO. The EMO is not pushed. If I knew what would cause an EMO signal (other than the real EMO pushed) it would help me. Is it possible I have a noise issue after installing the 3ph motor and VFD. Note that other than sharing mains AC power the VFD and cnc controller are isolated from each other, nothing is integrated yet.
Thanks in advance for any input
