Machine Abrupt Shutdowns
Posted: Thu Mar 16, 2023 6:34 pm
Hello,
We work with an MPU11 type CNC controller with a GPIO4D PLC on a 3 axis milling machine. We recently made the CNC12 upgrade to use a wireless MPG to be able to control the machine from outside of a safety cage. Ever since we updated the PLC program and parameters, the machine will on occasion just shut itself down and throw an MPG1 Encoder Error alarm. I do not know if the shutdown is tied to that alarm or not, because it seems like we always see that alarm when we first power on the machine. I have already disabled the encoder alarm messages and faults via the parameters but that has not done anything.
I have attached our most recent report from the machine for review. Hopefully someone can point me in the right direction. I ended up having to somewhat Frankenstein the PLC program together to get the wireless MPG to work correctly since our PLC program was a custom one. I do have full functionality of the wireless MPG other than feed rate override now though.
I also included the source code for our PLC program. It's based on a standard available one from Centroid.
