1 Alarms
1.5.1 Alarm description
3261 Workpiece not available
Scan
At Power On and active MD "Load workpiece last active after Power On"
Effect
The workpiece selected in the program pointer cannot be transferred from MMC to NCK.
Explanation
In the volatile NCK part program memory, a workpiece directory has been opened and not saved to harddisk be-
fore Power Off. After Power On, it is therefore not possible to transfer the workpiece entered in the program pointer
from harddisk to the NCK part program memory.
S
Remedy
Select existing workpiece
S
Preselect part program for execution (which means that the program pointer will automatically be assigned to
the workpiece belonging to the preselected part program).
Note
Applies as from SW 4
Note
Alarm is displayed with reference to channel
3262 Error in NCK FB
Scan
During cyclic operation of control
Effect
None
Explanation
The cyclic routines of the NCK FB have returned a value which is not equal to zero, and have requested the CAN-
CEL alarm class. The return value is output in the alarm as block number N.
Remedy
Evaluate the block number and check the NCK FB.
Continuation
Acknowledge the alarm with the Acknowledgement key
S
Note
Alarm 3262 is output only if appropriately configured by the machine manufacturer. An error has occurred in
the safety NCK–FB. For more information and remedy, refer to the manufacturer's documentation.
S
Applies as from SW 5.4.
3263 Impermissible axis position
Scan
When executing a part program
Effect
Interlocking of NC START
Machining stops
Explanation
The position of the material entry coordinate is outside the travel range of the block.
Remedy
Modify the part program.
Continuation
Acknowledge the alarm with the Acknowledgement key
Note
Applies as from SW 5.4
Note
Alarm is displayed with reference to channel
3264 NC STOP is effective at the end of block
Scan
When pressing NC STOP with active G04 S..., G14 and G24 with set MD bit "No NC STOP in the dwell block".
Effect
NC–STOP is delayed until the end of block
Explanation
NC STOP has been pressed in a dwell block in which NC STOP is not to become effective. Processing of the
dwell block continues, NS STOP becomes effective only at the end of the block.
Remedy
The message is deleted when the NC STOP has become effective at the end of the block or when the NC STOP
request has been cancelled with NC START.
S
Note
Alarm channel-specific
S
Applies as from SW 5.4
3265 IKA output without enable
Scan
Cyclically in IPO cycle
Effect
Feed stop of "slave axis" (IKA output variable)
Explanation
The IKA setpoint output will be disabled because the IKA output variable (normally an axis) was stopped for safety
reasons (e.g. feed disable, follow–up mode, override, controller enable).
Remedy
Remove the reason for the feed stop.
Caution:
If the reason for the feed stop is no longer present, the IKA link is automatically reactivated. As a result, the
"following error" that has been built up in the meantime is reduced again. The "reduction" is executed with the
modification limit of the IKA.
Note
Applies as from SW 6, the IKA number will be shown in the block number.
