Overview of Alarms
NCK alarms
17160 Channel %1 block %2 no tool selected
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: An attempt has been made to access the current tool offset data via the system variables:
$P_AD [n]: Contents of the parameter (n: 1 - 25)
$P_TOOL: Active D number (tool edge number)
$P_TOOLL [n]: Active tool length (n: 1- 3)
$P_TOOLR: Active tool radius
although no tool had been selected previously.
Reaction: Interpreter stop
NC Start disable in this channel.
Interface signals are set.
Alarm display.
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 MD 22550: TOOL_CHANGE_MODE
New tool offset for M function
Modify MD 22560: 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 Clear alarm with the RESET key. Restart part program
Continuation:
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.
Alarm display.
Remedy: --
Program Clear alarm with the RESET key. Restart part program
Continuation:
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
command, then the D number set by machine data $MC_CUTTING_EDGE_DEFAULT will be active
automatically. 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 Clear alarm with NC START or RESET key and continue the program.
