Spindle %2 Thread Might Be Damaged; Block %2 Thread Cutting: Maximum Speed Axis %3 Exceeded %4; Block %2 Zero Velocity Of Thread Axis At Position %3 Reached - Siemens Sinamics S120 Diagnostic Manual

22260 [Channel %1: ] Spindle %2 thread might be damaged
Parameters: %1 = Channel number
%2 = Axis name
%3 = Block number
Definitions: When DECODING SINGLE BLOCK has been selected and there is a chain of thread blocks, then machining pauses
occur at the block limits until the next block is executed with the new NC Start.
In normal single block mode, the program is stopped by a higher-level logic only at the block boundaries at which no
contour distortions or contour errors can occur. With chained thread blocks, this is the last thread block!
Reaction: Alarm display.
Remedy: If only one thread block has been programmed, the alarm message can be ignored.
If there are several consecutive thread blocks, this machining section must not be executed in the automatic DECOD-
ING SINGLE BLOCK mode.
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
22270 [Channel %1: ] Block %2 thread cutting: Maximum speed axis %3 exceeded %4
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis name
%4 = Velocity
Definitions: Thread cutting with G33, G34, G35: The thread axis (pitch axis) velocity calculated exceeds the maximum permissible
axis velocity MD32000 $MA_MAX_AX_VELO. The calculated axis velocity is displayed.
The velocity of the thread axis is dependent upon:
- The current spindle speed
- The programmed thread pitch
- The programmed thread pitch change and thread length (G34, G35)
- The spindle override (path and individual axis overrides are ineffective)
Reaction: Alarm display.
Remedy: Reduce the spindle speed or thread pitch (thread pitch change).
Program Clear alarm with the Delete key or NC START.
Continuation:
22275 [Channel %1: ] Block %2 zero velocity of thread axis at position %3 reached
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Position
Definitions: An axis standstill was reached at the specified position during thread cutting with G35 due to the linear decrease in
the thread pitch. The standstill position of the thread axis depends on:
- Programmed thread pitch decrease
- Thread length
Reaction: Alarm display.
Remedy: Change at least one of the above factors.
Program Clear alarm with the Delete key or NC START.
