Overview of Alarms
NCK alarms
Definitions: If an attempt is made to define or cancel a tool adapter assignment with reference to a magazine loca-
tion and this magazine location already has another tool adapter and/or a tool is located in the adapter
or - when canceling an assignment - a tool is still at the location, this alarm will appear. If machine data
MD18108 $MN_MM_NUM_SUMCORR has the value -1, adapters cannot be generated by a write
operation to an adapter which is not already defined. While the machine data has this value, you can
only write adapter data to adapters which have already been (automatically) assigned to magazine
locations.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: - Assign max. one adapter to a magazine location.
- The magazine location must not contain a tool.
- MD18108 $MN_MM_NUM_SUMCORR has value -1: If an alarm occurs when writing one of the sys-
tem variables $TC_ADPTx (x=1,2,3,T), the write operation must be modified such that only adapter
data which are already associated with the magazine locations are written.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
17270 [Channel %1: ] Block %2 call-by-reference: illegal variable
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: Machine data and system variables must not be transferred as call-by-reference parameters.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Modify NC program: Assign the value of the machine data or of the system variable to a program-local
variable and transfer this as parameter.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
17500 [Channel %1: ] Block %2 axis %3 is not an indexing axis
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis name, spindle number
Definitions: An indexing axis position has been programmed for an axis with the keywords CIC, CAC or CDC that
has not been defined as indexing axis in the machine data.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Please inform the authorized personnel/service department. Remove programming instruction for
indexing axis positions (CIC, CAC, CDC) from the NC part program or declare the relevant axis to be
an indexing axis.
Indexing axis declaration:
Modify MD30500: $MA_INDEX_AX_ASSIGN_POS_TAB (indexing axis assignment)
The axis will become an indexing axis when an assignment to an indexing position table was made in
the stated MD. 2 tables are possible (input value 1 or 2).
Modify MD10900 $MN_INDEX_AX_LENGTH_POS_TAB_1
Modify MD10920 $MN_INDEX_AX_LENGTH_POS_TAB_2 (Number of positions for 1st/2nd indexing
axis)
Standard value: 0 Maximum value: 60
Modify MD10910 $MN_INDEX_AX_POS_TAB_1 [n]
Modify MD10930 $MN_INDEX_AX_POS_TAB_2 [n]
(Positions of the 1st indexing axis) The absolute axis positions are entered. (The list length is defined
via MD10900 $MN_INDEX_AX_LENGTH_POS_TAB_1).
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
17501 [Channel %1: ] Block %2 indexing axis %3 with Hirth tool system is active
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis name
