Overview of Alarms
NCK alarms
Definitions: A geometry axis has been programmed that cannot be imaged on any machine axis in the current
transformation (possibly there is no transformation active at the moment).
Example:
Without transformation: Polar coordinate system with X, Z, and C axis
With transformation: Cartesian coordinate system with X, Y, and Z, e.g. with TRANSMIT.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Activate transformation type with TRAORI (n) or do not program geometry axes that do not participate
in the transformation grouping.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
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- Clear alarm with NC START or RESET key and continue the program.
tinuation:
16421 [Channel %1: ] Block %2 angle %3 programmed repeatedly in the block
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Angle
Definitions: It is not allowed to program more than one PHI or PSI angle for an orientation vector in the same 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:
16422 [Channel %1: ] Block %2 angle %3 programmed repeatedly in the block
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Angle
Definitions: It is not allowed to program more than one rotation angle THETA for the orientation in one block. The
angle of rotation can either be programmed explicitly with THETA or by programing with Euler angles
or RPY angles.
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:
16423 [Channel %1: ] Block %2 angle %3 programmed repeatedly in the block
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Angle
Definitions: It is not allowed to program more than one polynomial for the orientation rotation angle with PO[THT]
in one block.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
