16420 Channel %1 block %2 axis %3 programmed repeatedly
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis name, spindle number
Definitions: It is not allowed to program an axis more than once.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Delete the axis addresses that have been programmed more than once.
Program Con-
tinuation:
Clear alarm with NC START or RESET key and continue the program.
16430 Channel %1 block %2 geometry axis %3 cannot traverse as positioning
axis in rotated coordinate system
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis name, spindle number
Definitions: In the rotated coordinate system, traversing of a geometry axis as positioning axis (i.e. along its axis
vector in the rotated coordinate system) would mean traversing of several machine axes. This is in
conflict with the positioning axis concept, however, in which one axis interpolator runs in addition to
the path interpolator.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Traverse geometry axes as positioning axes only with rotation deactivated. Deactivate rotation:
Vocabulary word ROT without further specification of axis and angle. Example: N100 ROT
Program Con-
tinuation:
Clear alarm with NC START or RESET key and continue the program.
16440 Channel %1 block %2 rotation programmed for non-existent geometry
axis
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis name, spindle number
Definitions: A rotation of a geometry axis which does not exist was programmed.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Change part program
Program Con-
tinuation:
Clear alarm with NC START or RESET key and continue the program.
16500 Channel %1 block %2 chamfer or rounding negative
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: A negative chamfer or rounding has been programmed under the vocabulary words CHF= ..., RND=...
.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Values for chamfers, roundings and modal roundings must be programmed with positive values only.
Program Con-
tinuation:
Clear alarm with NC START or RESET key and continue the program.
