Overview of Alarms
NCK alarms
16751 Channel %1 block %2 spindle/axis %3 SPCOF not executable
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis name, spindle number
Definitions: For the programmed function, the spindle must be in the open-loop control mode. In the positioning
or axis mode, the position control must not be deselected.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Put the spindle into open-loop control mode in the preceding block. This can be done with M3, M4 or
M5 for the relevant spindle.
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
16755 Channel %1 block %2 no stop required
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: No Stop is needed for the programmed function. A Stop is necessary after SPOSA or after M5 if the
next block is to be applied only after the spindle has come to a stop.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Do not write instruction.
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
16757 Channel %1 block %2 for following spindle %3 coupling as leading
spindle/axis already existing
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Following spindle number
Definitions: A coupling has been switched on in which the following spindle/axis has already been active as
leading spindle/axis in another coupling. Chained couplings cannot be processed.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Check in the parts program whether the following spindle/axis is already active as leading spindle/axis
in another coupling.
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
16758 Channel %1 block %2 for leading spindle %3 coupling as following
spindle/axis already existing
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Leading spindle number
Definitions: A coupling has been switched on in which the leading spindle/axis has already been active as
following spindle/axis in another coupling. Chained couplings cannot be processed.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Check in the parts program whether the leading spindle/axis is already active as following spindle/axis
in another coupling.
Program Clear alarm with NC START or RESET key and continue the program.
