Overview of Alarms
16798
Channel %1 block %2 axis %3 is following axis and prohibits axis container rota-
tion
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis name, spindle number
Definitions: The programmed axis/spindle is active as a slave axis/spindle in a coupling. When the
coupling is active, the axis container cannot be rotated.
Reactions: - Correction block is reorganized.
- Interface signals are set.
- Alarm display.
Remedy: Modify part program. Deactivate the coupling(s) for this axis/spindle before rotating the
axis container or execute the axis container rotation at a later time.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
16799
Channel %1 block %2 axis %3 is master axis and prohibits axis container rotation
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis name, spindle number
Definitions: The programmed axis/spindle is active as a master axis/spindle in a coupling. When the
coupling is active, the axis container cannot be rotated.
Reactions: - Correction block is reorganized.
- Interface signals are set.
- Alarm display.
Remedy: Modify part program. Deactivate the coupling(s) for this axis/spindle before rotating the
axis container or execute the axis container rotation at a later time.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
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)
Reactions: - 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 MD 30300 IS_ROT_AX.
Corresponding machine data:
Modify MD 30310: ROT_IS_MODULO
Modify MD 30320: 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
