Hi!

Sometimes our niigata horizontal machine center with fanuc 15m control enters single block mid program. Any ideas what might cause something like this? It usually happens when the machine is working at around X+500. Turning the table (B) a degree and back usually fixes the issue, until the next pass. Then all of a sudden the problem is gone, only to come back the next day

It's not the door switch, all lube levels are fine and it's not the programming as the same program works fine if u run it X-

Check ladder for coil G4.3 This bit goes on to put the machine into single block mode

Will do, thanks!
