Okuma Alarm-A 8559 Part turn device advanced too far
In program operation, when the turn-over unit advance command is executed, the unit advanced excessively.
If the turn-advance confirmation input signal goes ON while the unit is moving forward, it is judged that over-advance had occurred.
This alarm dose not occur with the advance command executed in manual operation mode.
Probable Faulty Locations
1)Program error(advance command was executed although the workpiece transfer loader is not at the correct position.)
2)Workpiece transfer position setting error
