Overview of Alarms
NCK alarms
20094 Axis %1 function has been aborted
Parameters: %1 = Axis name, spindle number
Definitions: The function has been aborted. The possible reasons for this are:
- Because a pulse disable has occurred, the torque can no longer be provided.
- The PLC has removed the acknowledgments.
The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY (channel not
ready).
Reaction: Mode group not ready.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Channel not ready.
Remedy: Check whether
- there is a pulse disable from the infeed/regenerative-feedback unit or from the PLC?
- the acknowledgement bits have been deleted by the PLC even though NCK has not requested
deselection?
Program Clear alarm with the RESET key in all channels of this mode group. Restart part program.
Continuation:
20095 Axis %1 illegal torque, current torque %2
Parameters: %1 = Axis name, spindle number
%2 = Current holding torque when brake test selected
Definitions: The current holding torque, when brake test selected, cannot be attained with the present
parameterization of the brake test.
Reaction: Alarm display.
Remedy: Check the parameterization for the brake test function check:
- The torque for the counterweight in the drive machine data 1192 should be nearly the same as the
current holding torque. The current holding torque is displayed in the alarm text.
- The torque set for the $MA_SAFE_BRAKETEST_TORQUE must be greater than the current holding
torque.
Program Clear alarm with the Delete key or NC START.
Continuation:
20096 Axis %1 brake test aborted, additional information %2
Parameters: %1 = Axis name, spindle number
%2 = Error information based on $VA_FXS_INFO
Definitions: The brake test has detected a problem. The additional info provides more detailed information on the
cause of the alarm. The explanation can be found in the $VA_FXS_INFO system variable
documentation.
Additional information:
0: No additional information available.
1: Axis type is not a PLC or command axis.
2: End position reached, motion completed.
3: Abort by NC RESET (key reset).
4: Moved out of monitoring window.
5: Torque reduction rejected by drive.
6: PLC has cancelled enables.
Reaction: Interface signals are set.
Alarm display.
Remedy: Note the supplementary conditions of the brake test, see additional info.
Program Clear alarm with the Delete key or NC START.
