OSP-P20L Alarm and Error List (Error)-1

ALARM & ERROR LIST (ERROR)

8500 Cut-off error
[Code]
1->After the cut-off confirmation device advance command (M793) was executed, no advance answer signal was input within the cut-off detection time.
[Probable Fault Cause]
Cut-off tool broken
[Measures to Take]
Replace the cut-off tool insert.

8501 ATC shutter door not closed
A cutting feed command was executed while the shutter door was not closed.

8502 Tool change position travel impossible
The tool change position travel command G21 was executed when the conditions for G21 were not satisfied.
(G21 is also executed internally during execution of ATC macro commands G171 and M421.)
[Code]
1->The turret indexing status is as follows:
HP=1: Turret T1 of MacTurn, or turret T2 of LU45-MATC-Y is not indexed to the ATC position.
HP=2: Turret T2 of MacTurn, or turret T3 of LU45-MATC-Y is not indexed to the ATC position.
HP=3: Turret T1 of LU45-MATC-Y is not indexed to the ATC position.
[Probable Fault Cause]
1) When HP = 1, tool change position data for the turret station on which the L-tool is mounted,
When HP = 2, tool change position for the turret station on which the front milling tool is mounted,
(for MacTurn, tool change position for the turret station on which the milling tool is mounted),
When HP = 3, tool change position for the turret station on which the front milling tool is mounted.
Therefore, this alarm occurs if the turret station mounting position for the corresponding tool has not finished indexing when the G21 HP=* command is issued. Correct the turret index position, and then execute the G21 HP=* command again.

when the changer arm is present at the EAMG position.

8570 Magazine tool No.
The input signal from the magazine tool presence confirmation proximity switch provided at the magazine ATC position
does not match the pot data indexed to the magazine ATC position set on the "*ATC MAGAZINE INFORMATION*" screen
in tool data setting mode.
[Target] System
[Code] X
1->Although tool data is displayed on the "*ATC MAGAZINE INFORMATION*" screen, the magazine tool presence confirmation
proximity switch is OFF.
2->Although no tool data is displayed on the "*ATC MAGAZINE INFORMATION*" screen, the magazine tool presence confirmation
proximity switch is ON.

The "*ATC MAGAZINE INFORMATION*" screen displays tools loaded in each magazine pot. Therefore, for a pot
indexed to the magazine ATC position, the tool presence/absence data on the "*ATC MAGAZINE INFORMATION*" screen
should always match the input signal state from the magazine tool presence confirmation proximity switch.
