Overview of Alarms
NCK alarms
12630 [Channel %1: ] Block %2 skip ID/label in control structure not allowed
Parameters: %1 = Channel number
%2 = Block number
Definitions: Blocks with control structures (FOR, ENDIF, etc.) cannot be concealed and must not contain any
labels.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Modify part program: Reproduce skip ID via an IF query. Write the label alone in the block before the
control structure block.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
12640 [Channel %1: ] Block %2 invalid nesting of control structures
Parameters: %1 = Channel number
%2 = Block number
Definitions: Error in program run: Opened control structures (IF-ELSE-ENDIF, LOOP-ENDLOOP etc.) are not ter-
minated or there is no beginning of loop for the programmed end of loop.
Example:
LOOP ENDIF ENDLOOP
Reaction: Interpreter stop
NC Start disable in this channel.
Interface signals are set.
Alarm display.
Remedy: Correct part program in such a way that all opened control structures are also terminated.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
12641 [Channel %1: ] Block %2 maximum nesting depth of control structures
exceeded
Parameters: %1 = Channel number
%2 = Block number
Definitions: Max. nesting depth control structures (IF-ELSE-ENDIF, LOOP-ENDLOOP etc.) exceeded. At the
present time, the max. nesting depth is 8.
Reaction: Interpreter stop
NC Start disable in this channel.
Interface signals are set.
Alarm display.
Remedy: Correct part program. If necessary, move parts to a subroutine.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
12650 Channel %1 block %2 axis identifier %3 different in channel %4
Parameters: %1 = Channel number
%2 = Block number
%3 = Source symbol
%4 = Channel number with different axis definition
Definitions: In cycles that are preprocessed at Power On, only those geometry and channel axis identifiers may
be used that exist in all channels with the same meaning. In different channels, different axis indices
are assigned to the axis identifier.
The axis identifiers are defined via MD20060 $MC_AXCONF_GEOAX_NAME_TAB and MD20080
$MC_AXCONF_CHANAX_NAME_TAB. Example: C is the 4th channel axis in channel 1 and the 5th
channel axis in channel 2.
If the axis identifier C is used in a cycle that is preprocessed at Power On, then this alarm is issued.
Reaction: Interpreter stop
NC Start disable in this channel.
Interface signals are set.
Alarm display.
