Channel %1 block %2: The axis or frame name %3 contained in
$NK_AXIS[%4] is unknown
Parameters:
%1 = Channel number
%2 = Block number, label
%3 = Axis or frame name
%4 = Index of the chain element
Definitions:
An unknown name was entered in the element of a kinematic chain in the component $NK_AXIS[...].
The name entered must be either a machine axis identifier or the name of a variable made available
by the OEM software.
Reaction:
Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy:
Enter a valid name in $NK_AXIS[...].
In a regular case (without OEM software), that is a machine axis identifier.
An empty string is also a valid name. That defines a constant chain link.
Program
Continuation:
Clear alarm with NC START or RESET key and continue the program.
26280
Channel %1 axis %2 risk of collision %3 %4
Parameters:
%1 = Channel number
%2 = Axis name, spindle number
%3 = 1st protection zone
%4 = 2nd protection zone
Definitions:
The indicated axis was stopped due to the risk of collision.
Reaction:
Alarm display.
Remedy:
In JOG mode: Retract axis from danger zone.
In automatic mode: Determine reason for the risk of collision and eliminate. Possible reasons: wrong
NC program, too large handwheel overrides, axis couplings and vice-versa impairing of two channels.
Program
Continuation:
Alarm display showing cause of alarm disappears. No further operator action necessary.
26282
Channel %1 block %2: Invalid definition of the protection zones or the
kinematic chains.
Parameters:
%1 = Channel number
%2 = Block number, label
Definitions:
There are no valid definitions of the protection zones and / or the kinematic chains.
This alarm only occurs if an error occurred the last time the procedure PROTA was called, and its
cause has not been eliminated.
Reaction:
Correction block is reorganized.
Alarm display.
NC Stop on alarm.
Remedy:
Protection zones and kinematic chains must be defined without errors.
This is achieved by calling the procedure PROTA and closing it without errors.
Program
Continuation:
Clear alarm with NC START or RESET key and continue the program.
