Overview of Alarms
NCK alarms
4402 %1 causes a machine data reset
Parameters: %1 = Machine data
Definitions: If this machine data is set, the current machine data values are overwritten by the default values at
the next ramp-up. Under certain circumstances, this may cause data loss (even in the buffered mem-
ory).
Reaction: Alarm display.
Remedy: Please inform the authorized personnel/service department. If the control includes user data that has
not yet been saved, then a data backup must be performed before the next NCK power-up. By man-
ually resetting the altered MD to the value it had before the last power-up, reorganization of the mem-
ory can be avoided.
Program Con- Alarm display showing cause of alarm disappears. No further operator action necessary.
tinuation:
4502 [Channel %1: ] Anachronism %2(%3) -> %4
Parameters: %1 = Channel number
%2 = String: MD identifier
%3 = String: MD identifier
%4 = String: MD identifier
Definitions: Previously, in MD20110 $MC_RESET_MODE_MASK Bit4 and Bit5, the reset behavior of the 6th or
8th G groupe was determined. This setting is now made in MD20152 $MC_GCODE_RESET_MODE.
In order to ensure compatible handling of "old" data backups, the "old" values are taken from
MD20110 $MC_RESET_MODE_MASK and entered in MD20152 $MC_GCODE_RESET_MODE.
Reaction: Alarm display.
Remedy: --
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
4503 [TO unit %1: ] H number %2 assigned more than once. H number linked
again.
Parameters: %1 = TO unit
%2 = H number
Definitions: This error can only occur when MD10880 $MN_MM_EXTERN_CNC_SYSTEM= 1 or 2. The Power
ON effective MD10890, $MN_EXTERN_TOOLPROG_MODE, bit 3 has been reset. On reconstructing
data handling after Power ON, it has been found that different edges of the same TO unit have the
same H number. They had been linked previously. They are linked again and MD10890
$MN_EXTERN_TOOLPROG_MODE, bit 3 is set again.
Reaction: Alarm display.
Remedy: H numbers must be assigned only once in a TO unit. Then, MD10890,
$MN_EXTERN_TOOLPROG_MODE, bit 3 can be set = 0 and a restart can be performed.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
4600 Invalid handwheel type for handwheel %1
Parameters: %1 = Handwheel number
Definitions: The handwheel type (hardware segment) for handwheel %1 requested through MD11350
$MN_HANDWHEEL_SEGMENT is invalid.
Reaction: Interface signals are set.
Alarm display.
Remedy: Configure a valid type for the corresponding handwheel through MD11350
$MN_HANDWHEEL_SEGMENT.
Program Con- Switch control OFF - ON.
tinuation:
2-54
