Issue Description & Safety Warning
The Fanuc R-30i Series Robot Controller has triggered a critical Paint Plug-In internal error alarm.

Official Troubleshooting Steps
Cause:This error is caused when a internal problem has occurred within the Paint Plug In software. This fault is almost always caused by style paths which do things which were not anticipated when this software was written. The reasons for this could be: 1. The path is too fast 2. The instructions (PPS and PPE) are too close together 3. The delay and timing values specified in your Paint Plug In Setup are too large or do not make sense. 4. Your robot's CPU has failed. Remedy:Write down the exact error number and message shown. Write down exactly what your robot was doing at the time of the failure. Make sure you include: Program name, line number, robot's location in the work cell, any cell I/O or other communication activity, and exactly what the robot was doing right before the fault occurred. This fault is usually fixed by doing a COLD start. If that does not work, contact your supervisor or call your local FANUC representative.
