Overview of Alarms
NCK alarms
20141 Channel %1 motion synchronous action: illegal axis type
Parameters: %1 = Channel number
Definitions: The requested command is not permissible in the current axis status for the command axis or spindle.
This alarm occurs with command axes (POS, MOV), spindle commands from motion synchronous
actions (M3/M4/M5, SPOS), coupled motion (TRAILON, TRAILOF) and lead value coupling
(LEADON, LEADOF).
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: First stop the axis or deactivate the coupling, then select a new status.
Program Clear alarm with the RESET key. Restart part program
Continuation:
20142 Channel %1 command axis %2: rotation of axis container already
enabled
Parameters: %1 = Channel number
%2 = Axis
Definitions: The synchronized action instruction is not allowed on a spindle enabled for the axis container rotation.
The alarm only occurs if the spindle is handed to another NCU.
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Initiate the synchronized action instruction before the axis container rotation enable or after the end of
the rotation (depending on the application).
Program Clear alarm with the RESET key. Restart part program
Continuation:
20143 Channel %1 axis %2 command axis cannot be started as it is controlled
by the PLC
Parameters: %1 = Channel number
%2 = Axis name, spindle number
Definitions: An attempt has been made to start a command axis by means of a block-related or modal
synchronous action. This start is not possible as the axis is controlled by the PLC.
Reaction: Alarm display.
Remedy: End control of the axis by the PLC and therefore return it to the channel or start the command axis
with a static synchronous action.
Program Clear alarm with the Delete key or NC START.
