1 Alarms
1.5.1 Alarm description
3021 Contour violation with tool radius comp.
Scan
When executing a part program, with active TRC
Not:
S
In the selection block
S
In the deselection block
Effect
A contour violation has occurred on the workpiece. The program is continued, nevertheless (see MD 5024, bit 0).
The alarm can be cancelled with the acknowledge key.
Explanation
– The contour calculation results in a traversing movement which is opposite to the programmed movement
(e.g. when machining an internal circle, where the milling radius is larger than the circle radius).
– Between two blocks in the TRC plane, too many blocks have been programmed outside the TRC plane (see
also Programming Guide, Section 11.11). In this case, the block number displayed indicates the 4th block
outside the TRC plane.
S
Remedy
Check programming.
S
Deselect correction at a suitable point and select it again.
S
Check tool used against specifications
(tool radius too large?).
S
Note
Alarm is displayed with reference to channel
S
In the case of an error, the block number indicated refers to the 4th block outside the compensation plane
(TRC). See Programming Guide Section 11.1.
3022 Too many spindles programmed
S
Scan
When executing part program blocks in AUTOMATIC or MDA
S
Effect
Function is not executed
Explanation
Only one spindle may be programmed in any one part program block.
Remedy
Divide spindle programming into two or more blocks.
3023 Wrong spindle position in setting data
Scan
The alarm is output if M19 is programmed without an S value with MDA or in a part program and if an illegal value
is set in the spindle setting data for oriented spindle stop (M19).
S
Effect
Interlocking of NC START
S
Machining stops
Explanation
An illegal value has been entered in the spindle setting data for oriented spindle stop (M19).
Remedy
Enter legal value in setting data
permissible range 0 – 359.99
3024 Display description missing
S
Scan
On display selection
S
Effect
Selected display does not appear
Explanation
Using a programmed softkey, an attempt has been made to select a display not available in the UMS or system
memory.
Remedy
With the aid of the NC workstation, the programmed display number and softkey function must be checked.
3025 Display description has errors
S
Scan
On display selection
S
Effect
Selected display does not appear
Explanation
On checking the display information an error has been discovered, e.g.:
S
The programmed display type is unknown
S
Block increment for the extended table display is incorrect (must always be 1 for absolute display)
Remedy
Check the display description with the NC workstation, in particular the information for data group, data type and
format.
