Overview of Alarms
NCK alarms
Remedy: Program or activate a tool offset in the NC program before using the system variables.
Example:
N100 G.. ... T5 D1 ... LF
With the channel-specific machine data:
Modify MD22550 $MC_TOOL_CHANGE_MODE
New tool offset for M function
Modify MD22560 $MC_TOOL_CHANGE_M_CODE
M function with tool change
It is established whether a tool offset is activated in the block with the T word or whether the new offset
values are allowed for only when the M word for tool change occurs.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
17170 [Channel %1: ] Block %2 number of symbols too large
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: The predefined symbols could not be read in during power-up.
Reaction: Interpreter stop
NC Start disable in this channel.
Interface signals are set.

Remedy: --
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
17180 [Channel %1: ] Block %2 illegal D number
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: In the displayed block, access is made to a D number that is not defined and therefore is not available.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Check tool call in the NC parts program:
- Correct tool correction number D programmed? If no D number is specified with the tool change com-
mand, then the D number set by MD20270 $MC_CUTTING_EDGE_DEFAULT will be active automat-
ically. It is D1 by default.
- Tool parameters (tool type, length,...) defined? The dimensions of the tool edge must have been
entered previously either through the operator panel or through a tool data file in NCK.
Description of the system variables $TC_DPx[t, d] as included in a tool data file.
x ... Correction parameter number P
t ... Associated tool number T
d ... Tool correction number D
Program Con- Clear alarm with NC START or RESET key and continue the program.
