Overview of Alarms
NCK alarms
16800 [Channel %1: ] Block %2 traverse instruction DC/CDC for axis %3 not
allowed
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis name, spindle number
Definitions: The keyword DC (Direct Coordinate) can only be used for rotary axes. This causes approach of the
programmed absolute position along the shortest path.
Example:
N100 C=DC(315)
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Please inform the authorized personnel/service department.
Replace the keyword DC in the displayed NC block by specifying AC (Absolute Coordinate).
If the alarm display is the result of an error in the axis definition, the axis can be declared as a rotary
axis by means of the axis-specific MD30300 $MA_IS_ROT_AX.
Corresponding machine data:
Modify MD30310: $MA_ROT_IS_MODULO
Modify MD30320: $MA_DISPLAY_IS_MODULO
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
16810 [Channel %1: ] Block %2 traverse instruction ACP for axis %3 not
allowed
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis name, spindle number
Definitions: The keyword ACP (Absolute Coordinate Positive) is only allowed for "modulo axes". It causes
approach of the programmed absolute position in the specified direction.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Please inform the authorized personnel/service department.
In the displayed NC block, replace the keyword ACP by specifying AC (Absolute Coordinate).
If the alarm display is based on an incorrect axis definition, the axis with the axis-specific MD30300
$MA_IS_ROT_AX and MD30310 $MA_ROT_IS_MODULO can be declared a rotary axis with modulo
change.
Corresponding machine data:
Modify MD30320 $MA_DISPLAY_IS_MODULO
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
16820 [Channel %1: ] Block %2 traverse instruction ACN for axis %3 not
allowed
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis name, spindle number
Definitions: The keyword ACN (Absolute Coordinate Negative) is only allowed for "modulo axes". It causes
approach of the programmed absolute position in the specified direction.
Reaction: Interpreter stop
NC Start disable in this channel.
Interface signals are set.
Alarm display.
Remedy: Please inform the authorized personnel/service department.
In the displayed NC block, replace the keyword ACN by specifying AC (Absolute Coordinate).
If the alarm display is based on an incorrect axis definition, the axis with the axis-specific machine data
MD30300: $MA_IS_ROT_AX and MD30310: $MA_ROT_IS_MODULO can be declared a rotary axis
with modulo change.
Corresponding machine data:
MD30320: $MA_DISPLAY_IS_MODULO
