VFD Randomly spooling down
Posted: Tue Sep 28, 2021 9:05 pmGood afternoon!
My machine is rockin', its really doing well. Spite a few small issues that I am working out as we go.
But this one, with the VFD REALLY seems to be a random issue, and I can't seem to track it down.
I am using the HUANYANG RS-485 Plugin from Dan911. Everything works perfect... Then I hear the spindle spooling down, and I get some errors : e.ol.n & e.ol.a.
I hit the CYCLE STOP, wait for the spindle to stop. Click SPINDLE START, wait for it to hit the target RPM, and CYCLE START and it runs again, with no issue. The error "Self Cleared" on the VFD and its cool the the touch, as is the spindle. Then it will run fine for 2-3 more hours no issue, then BAM same thing all over again.
I have the VFD setup as per instructions, as well as the settings for the HUANYANG plug-in setup.
Im not really sure where to look next.
