Overview of Alarms
NCK alarms
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: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Please inform the authorized personnel/service department. Put the master spindle/axis with spin-
dle/axis exchange into the necessary channel or release from the PLC.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
16783 [Channel %1: ] Block %2 master spindle/axis %3 not available
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis name, spindle number
Definitions: A coupling has been switched on in which the master spindle/axis is currently not available. Possible
causes:
- Setpoint linkage has been selected and spindle/axis is active in the other channel.
- The spindle/axis has been accessed by the PLC and has not yet been released.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Please inform the authorized personnel/service department. Put the master spindle/axis with spin-
dle/axis exchange into the necessary channel or release from the PLC.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
16785 [Channel %1: ] Block %2 identical spindles/axes %3
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis name, spindle number
Definitions: A coupling has been switched on in which the following spindle/axis is identical to the master spin-
dle/axis.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Please inform the authorized personnel/service department.
- Configure link accordingly in MD21300 $MC_COUPLE_AXIS_1)
- or modify part program.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
16786 [Channel %1: ] Block %2 coupling to master spindle %3 already exists
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Leading spindle number
Definitions: A coupling is to be switched on, in which the slave axis is already actively coupled with the other mas-
ter axis. Only one master spindle is allowed for the synchronous spindle function. The already active
master spindle is displayed as last alarm parameter.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Prior to switching on the new coupling, separate the existing coupling. If several master spindels/axes
are required, the ELG function will have to be used.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
16787 [Channel %1: ] Block %2 coupling parameter not changeable
Parameters: %1 = Channel number
%2 = Block number, label
