Overview of Alarms
NCK alarms
Remedy: Program the spindle speed under address S in [rpm] (in spite of axis mode); the direction of rotation
is given by the sign of the spindle lead:
- Positive thread pitch: Rotational direction as M03.
- Negative thread pitch: Rotational direction as M04 N2.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
16761 [Channel %1: ] Block %2 axis/spindle %3 not programmable in the
channel
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis name, spindle number
Definitions: Mistake in programming: The axis/spindle cannot be programmed in the channel at this time. This
alarm can occur when the axis/spindle is being used by another channel or by the PLC.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Modify part program. Use "GET()".
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
16762 [Channel %1: ] Block %2 spindle %3 thread function is active
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Spindle number
Definitions: Incorrect programming: the spindle function can currently not be executed. This alarm occurs when
the spindle (master spindle) is linked with the axes by an interpolation function.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Modify part program. Deselect thread cutting or tapping.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
16763 [Channel %1: ] Block %2 axis %3 programmed speed is illegal (zero or
negative)
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis name, spindle number
Definitions: A spindle speed (S value) was programmed with the value zero or with a negative value.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: The programmed spindle speed (S value) must be positive. Depending on the application case, the
value zero can be accepted (e.g. G25 S0).
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
16770 [Channel %1: ] Block %2 axis %3 no measuring system available
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis name, spindle number
