Definitions: The maximum permitted number of chain links contained in all chains is too large.
When determining the maximum number, a single chain link contained in several chains is counted
several times.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Reduce number of chain links contained in all chains.
This can be achieved e.g. by deactivating individual and currently not required chains and by entering
the zero string in the name of the chain.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
26214 [Channel %1: ] Block %2: The maximum permissible value of fine offset
in chain element %3 was exceeded
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Fine offset value
Definitions: The value in $NK_OFF_FINE or in a component of $NK_OFF_DIR is higher than the limit value
allowed by $NK_LIMIT_FINE.
For chain elements that describe an axis, the alarm refers to $NK_OFF_FINE, otherwise to
$NK_OFF_DIR.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Reduce the value in the specified component, or increase the permissible limit value in
$NK_LIMIT_FINE.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
26216 [Channel %1: ] Block %2: The axis direction in chain element %3 has not
been defined.
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Fine offset value
Definitions: The chain element describes an axis, the direction of which is defined by the value included in
$NK_OFF_DIR. The definition is valid only if the value of the vector is higher than 1.0e-6.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Enter a valid vector in $NK_OFF_DIR, or change the chain element type.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
26218 [Channel %1: ] Block %2: Invalid name in %3[%4]
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Name of the system variable
%4 = Index of the system variable
Definitions: A system variable of type STRING contains an invalid name.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Use a permissible name.
The permissible names can be found in the documentation of the system variables involved.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
