Okuma Alarm-A 1730 Turret clamp/position check error
The turret clamp signal is turned off during axis movement
[function generation] (except manual operation).
Or a mismatch between tool numbers has continued for more than 1[s].
None->Mismatch between programmed and actual tool numbers
1->During axis movement [function generation], the turret clamp confirmation signal went out.
2->A mismatch between the programmed tool number and the actual tool number is found after the turret has been clamped
3->A cutting feed command is issued while the NC turret is unclamped, and the turret is not clamped within 500[ms] after designation of the command.
4->The command of cutting-feed was performed by the state that was not “M-tool spindle edge angle” when L-tool or sensor is registered with present-tool.
5->The rapid feed or manual jog feed or puluse handle feed command is issued, while the NC turret is not clamped and turret index motor’s servo is OFF.
7->Turret positioning is not finished.
YY:Hexadecimal number of designated tool number
FFFFFFFF:A tool index command other than T1 was issued when an NC round table or stationary turret was mounted.
Probable Faulty Locations
1)An abnormality occurred in the turret clamp confirmation limit switch, turret-related wiring, or the turret index limit switch.
2)T-axis position encoder offset value
Measures to Take
X=None->Check the EC input related with the tool number.
X=1, 4 or 5->Check the clamp confirmation LS.
X=2->Check the EC input related with the tool number;
adjust the turret index solenoid when the turret overpasses the designated position.
