Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:

Channel %1 block %2 Illegal surface normal vector with 3D tool radius compensa-
tion
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: In 3D face milling, surface normal vector and path tangent vector must theoretically be
perpendicular to one another, i.e. they must be at 90° to one another. Since both vectors
can be programmed independently of each other, deviations from this angle are possible
and allowed. This alarm is generated when the angle between surface normal vector and
path tangent vector becomes less than the limit angle given by the machine data 21084
CUTCOM_PLANENORMAL_PATH_LIMIT.
Reactions: - Correction block is reorganized.
- Local alarm reaction.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm at block end.
Remedy: Modify part program.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
10770
Channel %1 block %2 change of corner type due to change of orientation with
active tool radius compensation
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: The type of a corner (inside or outside corner) depends not only on the programmed path
but also on the tool orientation. For this purpose, the programmed path is projected in the
plane perpendicularly to the actual tool orientation and the corner type is determined
there. If a change in orientation is programmed (in one or several blocks) between two
traversing blocks, resulting in the type of corner at the end of the first traversing block
being different from that at the start point of the second block, the above error message is
issued.
Reactions: - Correction block is reorganized.
- Local alarm reaction.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm at block end.
Remedy: Modify part program.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
10771
Channel %1 block %2 overflow of local block buffer due to orientation smoothing
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: This error occurs when more blocks must be buffered than memory space is available.
This error can only occur when the software has been incorrectly configured.
Reactions: - Correction block is reorganized.
- Local alarm reaction.
- Interface signals are set.
- Alarm display.
