Overview of Alarms
NCK alarms
Remedy: Indicate a valid activation parameter ("A", "a", "I", "i", "P", "p").
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
26274 [Channel %1: ] Block %2: Chain %3 referred to in $NP_CHAIN_NAME[%4]
was not found
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Name of the chain
%4 = Index of protection area
Definitions: The kinematic chain referred to in the protection area definition ($NP_CHAIN_NAME[...]) was not
found.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Indicate in $NP_CHAIN_NAME[...] the name of an existing kinematic chain or define a chain with the
name indicated.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
26276 [Channel %1: ] Block %2: Chain element %3 referred to in
$NP_CHAIN_ELEM[%4] was not found
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Name of the chain element
%4 = Index of protection area
Definitions: The kinematic chain element referred to in the protection area definition ($NP_CHAIN_ELEM[...]) was
not found.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Indicate in $NP_CHAIN_ELEM[...] the name of an existing chain element or define a chain element
with the name indicated.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
26278 [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 Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
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
