Overview of Alarms
NCK alarms
16777 Channel %1 block %2 coupling: following axis %3 for lead axis %4 not
available
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis name, spindle number
%4 = Axis name, spindle number
Definitions: A coupling has been switched on in which the slave spindle/axis is currently not available. Possible
causes:
- The spindle/axis is active in the other channel.
- The spindle/axis has been accessed by the PLC and has not yet been released.
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Please inform the authorized personnel/service department. Put the master spindle/axis with
spindle/axis exchange into the necessary channel or release from the PLC.
Program Clear alarm with the RESET key. Restart part program
Continuation:
16778 Channel %1 block %2 coupling: Ring coupling at following axis %3 and
leading axis %4 impermissible
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis name, spindle number
%4 = Axis name, spindle number
Definitions: A coupling has been switched on which results in a cyclic coupling, allowance being made for further
couplings. This cyclic coupling cannot be uniquely computed.
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Please inform the authorized personnel/service department. Configure link in accordance with the MD
or correct NC part program (channel MD: COUPLE_AXIS_n).
Program Clear alarm with the RESET key. Restart part program
Continuation:
16779 Channel %1 block %2 coupling: too many couplings for axis %3, see
active leading axis %4
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis name, spindle number
%4 = Axis name, spindle number
Definitions: More leading axes and spindles were defined for the specified axis/spindle than are allowed. The last
parameter to be specified is a leading value object/leading axis to which the specified axis/spindle is
already linked.
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Modify part program.
Program Clear alarm with the RESET key. Restart part program
