1 Alarms
1.5.1 Alarm description
2082 TRC plane cannot be defined
Scan
When processing a part program in AUTOMATIC
S
Effect
Machining is stopped
S
Interlocking of NC START
Explanation
The axes of the TRC plane selected do not exist.
S
Remedy
Machine data "Abscissa for prog. G16"
S
Machine data "Ordinate for prog. G16"
S
Machine data "Applicate for prog. G16"
S
Select correct plane using G16
Note
Alarm is displayed with reference to block and channel
2083 Contour violation with TRC
Scan
When TRC is selected in AUTOMATIC
Not: in the selection block
in the deselection block
Effect
A contour violation may have occurred on the workpiece. The program is continued if MD 5024, bit 0, is set or
machining is aborted.
This also depends on whether the alarm has been acknowledged with the Acknowledgement key or the Reset key.
Explanation
The calculated compensation results in a direction of travel that is opposite to the programmed direction.
S
Remedy
Check the program
S
Deselect the compensation at a suitable point and reselect
Note
Alarm is displayed with reference to block and channel
2087 Coordinate rotation/ZO not allowed
Scan
When working in AUTOMATIC or MDA
S
Effect
Interlocking of NC START
S
Machining is interrupted
S
Explanation
After selecting coordinate rotation (G54 to G59) a circular movement (G02, G03) was programmed in the follo-
wing block.
S
After selecting coordinate rotation (angle ≠ 0 degrees) the settable zero offset (G54 to G57) was changed.
S
After selecting coordinate rotation (angle ≠ 0 degrees) the plane (G16, G17, G18, G19) was changed.
S
Remedy
Correct program
S
The plane can only be changed if the angle of rotation is 0 degrees.
S
The settable zero offset (G54 to G57) can only be changed if the angle of rotation is 0 degrees.
S
Set angle of rotation in the settable zero offsets (G54 to G57) to 0 degrees and work only with G58 and G59.
Note
Alarm is displayed with reference to block and channel
2160 Illegal scale factor
Scan
When working in AUTOMATIC or MDA
S
Effect
Interlocking of NC START
S
Machining is interrupted
Explanation
The scale factor has exceeded the valid range of values:
+ P is negative
+ P = 0
+ P > 99.99999
Remedy
Note the valid range of values for scale factor:
(P = 0.00001 to 99.99999)
Note
Alarm is displayed with reference to block and channel
