1.5.1 Alarm description
2023 Invalid type of tool
Scan
When executing a part program
S
Effect
Interlocking of NC START
Explanation
A tool has been selected with unknown tool type (0, >59), or a tool of type 50..59 has been selected, even though
the tool offset memory has been formatted with fewer than 12 parameters.
Remedy
Enter a permissible tool type for the selected tool.
Note
Applies as from SW 4
Note
Alarm is displayed with reference to block and channel
2031 Weighting factor too large/small
Scan
When executing a part program
S
Effect
Interlocking of NC START
S
Machining stops
S
Deletion of part setpoint
Explanation
The actual axis velocity has become so large, as a result of recalculation with the specified weighting factor, that
the maximum permissible velocity with the axis-specific position control resolution set has been exceeded.
S
Remedy
Check NC machine data "Weighting factor" (MD 388*)
S
Program a lower velocity
S
Reduce the feedrate or rapid override
2036 G35 pitch decrease too high
Scan
When thread cutting
S
Effect
Interlocking of NC START
S
Machining stops
Explanation
The lead decrease in the thread is so large that a lead greater than or equal to 0 would result at the end of the
thread.
S
Remedy
Program a smaller lead decrease or a shorter thread
Note
Channel-specific
2037 Programmed S value too high
Scan
When executing a part program
Effect
None; for information only
S
Explanation
The programmed spindle speed in AUTOMATIC/MDA is too high.
S
Resulting velocity too high for thread, see Installation and Start–up Guide, Section 10.2.
S
Remedy
Program lower spindle speed
2038 Path feed too great
Scan
When executing a part program
S
Effect
Machining is interrupted
S
Interlocking of NC START
S
Axes go into follow-up mode, servo-enable is cancelled
Explanation
The axis velocity has been made so large by the programmed path feedrate that the maximum permissible axis
velocity with the position control resolution set has been exceeded.
The entered acceleration data are too small.
S
Remedy
Program a smaller path feedrate
S
Check interpolation combinations in the part program block
Note
Channel-specific
