I have a Yasnac i80 controller on a Kitamura Mycenter 1. Lately it has been giving me an issue in which the machine hangs (spindle stops spinning and movement stops) mid-program. It hangs while the spindle is in the air just before a ramping move. When it hangs, there is a flashing 'R' on the screen. This is similar to the flashing "MS" (minimum speed?) which happens when a speed greater than 10,000 RPM has been commanded without first warming up the machine at 5,000+ RPM, but here I am having a flashing "R."

This issue is also intermittent. Any ideas?
