I am having trouble with my machine at work. No one can figure out what the problem is so I am hoping someone here could help. The problem is that, during the automatic cycle the machine decides to stop cycle after a short run (maybe an hour or two). It stops because the status of the machine -
*(My machine has a program called VNC Viewer 4 that monitors the status of the tooling, the robotics, and a few other things. If the status is not satisfactory to the condition of the machine then cycle stops.)
- is flickering to "not in safe zone" (on the robotic arms) during the automatic cycle. It also starts bringing up various other faults which include "Spindle drive fault on #.." and "Slave disconnects/SOP Signal lost"(on the robot control penant). It seems to me to be a central electronical issue due to the varience in different fault codes when none of these faults are true. I know this is somewhat vague but I would appreciate any feedback that anyone was able to offer.
Most likely a dirty microswitch, or dirty optical switch, or magnetic sensor with a whisker on it.
See if you can manually cycle all micro switches multiple times.
A microswitch that is normally closed, but not making good contact can pickup noise, causing unpredictable events.
A sticking switch can cause a particular cycle to not complete.
WITH THE POWER REMOVED from the machine, give every visible connector a wiggle to reseat the pins.
Careful if plugging and unplugging boards. Configuration memory could be corrupted. If not sure, don't unplug.
External connectors to PCBs are less of a risk if they are wiring out to the machine. Be very careful with internal interconnect looms/plugs.
Cycle little used panel switches lots of times with the power removed if they might do something exciting.
Door switches, axis limit switch plungers often get gummed up.
Make sure power is off, as some unexpected move could injure you, especially if a switch change is what is stopping the cycle continuing.
You satisfy switch, and it can initiate movement. Tapping switches with a plastic screwdriver handle or similar will often unstick a stuck switch.
