Okuma Alarm-A 1243 Turret rotation conditions
Turret indexing was attempted when the turret indexing conditions are not met.
1->A turret index command was issued when the facing or OD tool clamp confirmation signal was OFF.
2->A T-command was issued when the touch setter is in advance position.
3->On the FTL machine, the Z-axis is located in a negative position beyond the interference position.
4->On the machine with Y-axis function, a turret index command was issued while the YS-axis is lower than the spindle center.
5->On the machine with NC turret, the simple tow-along tailstock is in connection.
8->A turret index command was issued while the YS-axis was located, in the machine coordinate system, lower than Spindle CENTER POSITION specified by the system parameter.
12->On the machine equipped with C-axis zero offset function by laser sensor, a turret index command was issued when the laser sensor retract confirmation input was OFF.
13->The turret index instruction which is divided impossibility was performed by the state which attached long tool (tool variety setting at ML with do tool) to turret T1 or the state which attached touch sensor of a measure within a machine specification.
14->When a long tool (tool type: ML) was mounted in the turret T1, a turret index command was issued with the shutter closed.
15->The turret rotation interlock against special long tool was activated because turret rotation was attempted with a special long tool mounted on the turret.
16->Turret rotation was attempted during spindle rotation.
Probable Faulty Locations
1->A turret index command was issued while a tool was projected for tool change or manual tool loading/unloading.
The signal wire from the proximity switch is damaged.
The hydraulic solenoid valve for clamping face/OD tool is broken.
8->A turret indexing command was issued while the Y-axis is in a negative position in Y-axis mode.
12->A turret index command was issued with the laser sensor located in advance position, or the laser sensor retract confirmation LS is at fault.
