Remedy: Modify part program.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
16424 [Channel %1: ] Block %2 coordinate %3 programmed repeatedly in the
block
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Coordinate
Definitions: It is not allowed to program a coordinate of the 2nd contact point of the tool for description of the tool
orientation several times in one block.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Modify part program.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
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:
Keyword ROT without further specification of axis and angle.
Example: N100 ROT
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
16440 [Channel %1: ] Block %2 rotation programmed for non-existent geometry
axis
Parameters: %1 = Channel number
%2 = Block number, label
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: Modify part program.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
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 keywords CHF= ..., RND=... or
RNDM=...
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- Clear alarm with NC START or RESET key and continue the program.
