[Channel %1: ] Block %2 illegal array index 1
Parameters:
%1 = Channel number
%2 = Block number, label
Explanation:
General:
Read or write access has been programmed to an array variable with an illegal 1st array index. The valid array indices must
lie within the defined array size and the absolute limits (0 - 32,766).
PROFIBUS I/O:
An illegal slot / I/O area index was used while reading/writing data.
Cause:
1.: Slot / I/O area index >= max. number of available slot / I/O areas.
2.: Slot / I/O area index references a slot / I/O area that has not been configured.
3.: Slot / I/O area index references a slot / I/O area that has not been released for system variables.
The following applies specifically: If the alarm occurs while writing one of the parameters $TC_MDP1/$TC_MDP2/$TC_MLSR,
check whether MD18077 $MN_MM_NUM_DIST_REL_PER_MAGLOC has been set correctly.
MD18077 $MN_MM_NUM_DIST_REL_PER_MAGLOC defines the number of different Index1 statements that may be made
for an Index2 value.
If an MT number is programmed, the value may collide with a previously defined T number or a previously defined magazine
number.
Reaction:
Correction block is reorganized.
Interface signals are set.

Remedy:
Correct the specification of array elements in the access instruction to match the defined size.

NC alarms
Explanation:
A value has been programmed that exceeds the value range or a limit value of a variable or a machine data item.
For example: In a string variable (e.g. GUD or LUD), a string needs to be written that exceeds the agreed string length in the
variable definition.
- If an illegal value is to be written to a tool or magazine management variable (e.g. illegal cutting edge number in
$TC_DPCE[x,y] or illegal magazine location number in $TC_MDP2[x,y])
- The value of MTL is incorrect. MTL must be programmed with a multitool location number of a multitool that is
programmed in the command T=magazine location number in the same NC block.
- An illegal value is to be written in $P_USEKT or $A_DPB_OUT[x,y]
- An illegal value is to be written in a machine data (e.g. MD10010 $MN_ASSIGN_CHAN_TO_MODE_GROUP[0] = 0)
- On accessing an individual frame element, a frame component other than TRANS, ROT, SCALE or MIRROR was addressed
or the CSCALE function was assigned a negative scale factor.
A multitool number has been programmed that collides with a previously defined T number or a previously defined
magazine number.
When programming DELMLOWNER: The command cannot be programmed with the T number of a tool that is part of a
multitool.

Explanation:
In the displayed block, a tool is accessed that is not defined and is therefore not available. The tool has been named by its
T number, its name or its name and duplo number.
If the function T=magazine location is activated and programmed, the programmed T number indicates the magazine
location number. The alarm can then indicate that the programmed magazine location number is illegal.
If the function T=magazine location is activated and programmed, and the multitool function is also activated and
programmed in the program line MTL, the alarm can also indicate that there is no multitool at the location programmed with
T=magazine location
or that there is no tool at the multitool location programmed with MTL.
Reaction:

Explanation:
A tool identifier which the NCK does not recognize was programmed.
Reaction:
Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy:
If the program pointer is at an NC block which contains the specified T identifier: If the program is incorrect, remedy the error
with a correction block and continue the program. If the data block is missing, create one. You can do this by downloading
a data block with all the defined D numbers onto the NCK (via HMI with overstore) and continue the program.
If the program pointer is at an NC block which does not contain the specified T identifier: The error occurred at an earlier point
in the program where the T command appeared, but the alarm was not output until the change command was detected.
If the program is incorrect - T5 programmed instead of T55 - the current block can be corrected with a correction block; i.e.
if only M06 is entered, you can correct the block with T55 M06. The incorrect T5 line remains in the program until it is
terminated by a RESET or end of program.
In complex program structures with indirect programming, it may not be possible to correct the program. In this case, you
can only intervene locally with an overstore block - with T55 in the example. If the data block is missing, create one. You can
do this by downloading the data block of the tool with all the defined D numbers onto the NCK (via HMI with overstore),
program the T command with overstore, and continue the program.

2: There is already a tool on the intended magazine or multitool location.
3: The adapter cannot be removed from the location because there is still a tool on the location.
4: An attempt is being made to bring a non-existent adapter to a magazine or multitool location.
5: The adapter cannot be deleted because it is still assigned to a location.
6: If $MN_MM_NUM_TOOL_ADAPTER = -1, all adapters or one adapter of type 1 cannot be deleted.
6: If $TC_ADPTT[n] = -1, a type 2 adapter cannot be deleted.
6: If $TC_ADPTT[0] = -1, no adapter can be deleted, if $MN_MM_NUM_TOOL_ADAPTER_TYPE2 > 0.
21: Grinding tools (type 4xx) and turning tools (type 5xx) are not allowed on a location with a new-type adapter (type 2):
22: An old-type tool adapter (type 1) cannot yet be assigned to a multitool location.
23: A new-type tool adapter (type 2) cannot yet be assigned to a magazine location.

%3 = Cause
Explanation:
A 'fixed-point approach in JOG' has been requested for an axis. This is not possible because:
Reason 1: The axis is involved in the active transformation.
Reason 2: The axis is a following axis in an active coupling.
The fixed point approach will therefore not be executed.

[Channel %1: ] Axis %2 fixed-point approach in JOG and override motion active
Parameters:
%1 = Channel number
%2 = Axis name, spindle number
Explanation:
'Fixed-point approach in JOG' is active for the axis, but another offset motion - for example a synchronization offset $AA_OFF
- has been interpolated simultaneously.
The position of the selected fixed-point is not reached if offset values are changed during the traversing motion.
The target point then becomes "fixed-point position + change in offset value".
The end point will be reached if the traversing motion is restarted after the offset value has been changed.
(For example: incremental traversing in which the traversing motion stops intermittently).
Reason:
Restarting the motion takes the current offset value into account.

[Channel %1: ] Axis %2 JOG to position and override motion active
Parameters:
%1 = Channel number
%2 = Axis name, spindle number
Explanation:
'JOG to position' is active for the axis, but an offset motion - for example a synchronization offset $AA_OFF - has been
interpolated simultaneously.
The position of the SD43320 $SA_JOG_POSITION is not reached if offset values are changed during the traversing motion.
The target point then becomes "Jog position + change in offset value".
The position SD43320 $SA_JOG_POSITION will be reached if the traversing motion is restarted after the offset value has

Explanation:
After starting the reference point approach, the rising edge of the reduction cam must be reached within the section
defined in the MD34030 $MA_REFP_MAX_CAM_DIST (phase 1 of referencing). (This error occurs only with incremental
encoders).
Reaction:

Determine the maximum possible distance from the beginning of reference motion up to the reduction cam and compare
with the value in MD34030 $MA_REFP_MAX_CAM_DIST, increase the value in the MD if necessary.
2. The cam signal is not received by the PLC input module.
Operate the reference point switch manually and check the input signal on the NC/PLC interface (route: Switch! Connector!
Cable! PLC input! User program).
3. The reference point switch is not operated by the cam.
Check the vertical distance between reduction cam and activating switch.

[Channel %1: ] Axis %2 no cam signal present
Parameters:
%1 = Channel number
%2 = Axis name, spindle number
Explanation:
At the beginning of phase 2 of reference point approach, the signal from the reduction cam is no longer available.
Phase 2 of reference point approach begins when the axis remains stationary after deceleration to the reduction cam. The
axis then starts in the opposite direction in order to select the next zero marker of the measuring system on leaving the
reduction cam or approaching it again (negative/positive edge).
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. Check whether the deceleration path after the approach
velocity is greater than the distance to the reference point cam - in which case the axis cannot stop until it is beyond the cam.
Use a longer cam or reduce the approach velocity in MD34020 $MA_REFP_VELO_SEARCH_CAM.
When the axis has stopped at the cam, it must be checked whether the signal DB31, ... DBX12.7 (Deceleration reference
point approach) is still available at the interface to the NCK.

[Channel %1: ] Axis %2 zero mark not found
Parameters:
%1 = Channel number
%2 = Axis name, spindle number
Explanation:
The hardware zero mark of the incremental position encoder or the substitute zero mark of the absolute position encoder
is not within a defined section.
Phase 2 of the reference point approach ends when the zero mark of the encoder has been detected after the rising/falling
edge of the NC/PLC interface signal DB31, ... DBX12.7 (Deceleration reference point approach) has given the trigger start.
The maximum distance between the trigger start and the zero mark that follows is defined in the MD34060
$MA_REFP_MAX_MARKER_DIST.
The monitor prevents a zero mark signal from being overtraveled and the next being evaluated as reference point signal.
(Faulty cam adjustment or excessive delay by the PLC user program).
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.
Check the cam adjustment and make sure that the distance is sufficient between the end of the cam and the zero marker
signal that follows. The path must be greater than the axis can cover in the PLC cycle time.
Increase the MD34060 $MA_REFP_MAX_MARKER_DIST, but do not select a value greater than the distance between the 2
zero markers. This might result in the monitor being switched off.

Parameters:
%1 = Channel number
%2 = Axis name, spindle number
Explanation:
In phase 2 of reference point approach (wait for zero mark), the cam end was reached but the reference point approach
velocity was not within the tolerance window. (This can occur when the axis is already at the end of the cam at the beginning
of reference point approach. Phase 1 is therefore considered as being already concluded and will not be started.)
Phase 2 has been interrupted (this time before the cam) and the reference point approach will be started once again
automatically with phase 1. If the approach velocity is not reached at the 2nd attempt either, referencing will be stopped
and the alarm displayed.

operating area with the softkeys "SETTINGDATA" and "JOG DATA", and preselect the G function G95 there. The JOG feedrate
can then be entered in [mm/rev]. (If 0 mm/rev is set as JOG feedrate, the control takes the value assigned in the axis-specific
machine data MD32050 $MA_JOG_REV_VELO or in the case of rapid traverse override MD32040
$MA_JOG_REV_VELO_RAPID).
The revolutional feedrate in JOG mode is deactivated by changing the G function from G95 to G94.

Explanation:
When using system variables, it is assumed that a read/write operation can access the required data successfully. In accesses
to encoder actual values or digital I/Os, the result depends on the availability of the corresponding hardware components.
If an access within synchronized actions does not return a valid value, alarm 20144 is output. Outside synchronized actions,
such a read/write access causes block execution to be interrupted until the result is available. Block execution is subsequently
continued.

specific enables has been reset for the displayed axis. The alarm can be reported with positioning axes, spindles and for axes
from the geometry grouping.
The axes entered in the channel-specific MD array MD20050 $MC_AXCONF_GEOAX_ASSIGN_TAB are regarded as axes
belonging to the geometry grouping. Servo enable must exist for all available geometry axes, regardless of whether or not
they are currently in motion.

[Channel %1: ] Block %2 transformation active: motion not possible
Parameters:
%1 = Channel number
%2 = Block number, label
Explanation:
The machine kinematics do not allow the specified motion.
Transformation-dependent error causes may be:
With TRANSMIT: There is a circular area around the pole, where positioning is not possible. This area exists because the tool
reference point cannot be traversed into the pole.
The area is defined by the following factors:
- Machine data (MD249.. $MC_TRANSMIT_BASE_TOOL_...)
- Active tool length compensation (see $TC_DP..).
Whether the tool length compensation is included in the calculation depends on the selected working plane (see G17,..).
The machine stops at the edge of the area where positioning is not possible.
For TRAINT: An attempt was made to activate a TRAINT transformation with Y(WCS)<>0. (The Y axis must be set to WCS=0

synchronized action is detected that immediately sets $AA_OFF for the axis (DO_$AA_OFF [<axis>] =<value>). Deselection
is executed and $AA_OFF not set again.
Reaction:
Correction block is reorganized.
Local alarm reaction.
Interface signals are set.
Alarm display.
NC Stop on alarm at block end.
Remedy:
Modify part program.
Programm
Clear alarm with NC START or RESET key and continue the program.

[Channel %1: ] Block %2 impermissible motion on change of tool direction and $AA_TOFF
active
Parameters:
%1 = Channel number
%2 = Block number, label
Explanation:
If an offset is active in tool direction via $AA_TOFF[i] there must not be a geometry axis movement in a block in which the
tool orientation is changed abruptly.
Abrupt changes of the tool orientation, whereby a movement of the geometry axes can be programmed simultaneously,
can, for example, occur during a plane change, tool change, or activation and deactivation of an orientable tool carrier.

[Channel %1: ] Block %3 axis %2 touch probe already deflected, edge polarity not possible
Parameters:
%1 = Channel number
%2 = Axis name, spindle number
%3 = Block number
Explanation:
The probe programmed under the keyword MEAS or MEAW is already deflected and has switched. For a further measuring
operation, the probe signal must first be canceled (quiescent state of the probe).
The axis display is of no significance at present but an axis-specific evaluation has been planned for later stages of
development.
Note:
If the MEAS or MEAW command is used in conjunction with a simulation system or a control system with simulated axes,
then MD13231 $MN_MEAS_PROBE_OFFSET must be checked in the event of an alarm.
The value in this machine data moves the MEAS switching position and must be less than the length of the programmed
measuring distance.
Reaction:
Local alarm reaction.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy:
Verify the starting position of the measuring operation or check the probe signals in the PLC interface DB10 DBX107.0 /
107.1 (Probe actuated key 1/key 2). Are the cables and connectors in good order?

[Channel %1: ] Block %3 axis %2 measurement not possible
Parameters:
%1 = Channel number
%2 = Axis name, spindle number
%3 = Block number
Explanation:
Measurement level 2 (MEASA, MEAWA, MEAC).
There is an error in the programmed measurement task.
Possible causes:
- Invalid measurement mode
- Invalid probe
- Invalid encoder
- Invalid number of measurement signal edges
- Identical measurement signal edges are only programmable in mode 2
- Invalid FIFO number
- Mismatch between the number of FIFOs programmed and the number of probes used in the measurement task.
Further causes:
A measurement task is already active (e.g. from a synchronized action).

[Channel %1: ] Block %3 axis %2 measurement canceled
Parameters:
%1 = Channel number
%2 = Axis name, spindle number
%3 = Block number
Explanation:
The measurement block has ended (the programmed end position of the axis has been reached) but the activated touch
probe has not yet responded.
Measurement level 2 (MEAWA, MEASA, MEAC)
Measured values cannot be converted to the workpiece coordinate system. The measured values of the GEO axes
programmed in the measurement task are only available in the machine coordinate system.
Causes:
Not all GEO axes were programmed in the measurement task. At least one measured value is therefore missing for
conversion back into the workpiece coordinate system.
Further causes:
The measurement tasks programmed for all GEO axes are not identical.
When making measurements without handshake, two probes must be available in drive parameters p0680 index 0 and 1.
Reaction:
Alarm display.
Remedy:
Check the traversing movement in the measurement block.
- Is it necessary in all cases for the activated probe to have switched up to the specified axis position?
- Are the probe, cable, cable distributor, terminal connections in good order?
- Is the probe correctly wired and configured on the hardware side (e.g. drive parameters p0488 and p0489)?
Either program all GEO axes explicitly or program the traversing movement with the POS[axis] command.

[Channel %1: ] Block %3 axis %2 touch probe not deflected, illegal edge polarity
Parameters:
%1 = Channel number
%2 = Axis name, spindle number
%3 = Block number
Explanation:
The selected probe is not (!) deflected and therefore cannot record any measured value from the deflected to the non-
deflected state.
Measurement level 2 (MEAWA, MEASA, MEAC)
The degree of deflection of the probe at the start of the measurement task is identical to the first programmed measurement
signal edge. The test is only performed in mode 2.
Reaction:
Local alarm reaction.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy:
- Check probe
- Check start positioning for measuring
- Check program

Error during output of cam switching signals via timer
Explanation:
The signal output activated by the MD10480 $MN_SW_CAM_TIMER_FASTOUT_MASK via the hardware timer (independent
of the clock grid) did not work. Cause: interpolation cycle is greater than 15 ms.
The alarm can be reprogrammed in the MD11412 $MN_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.

Limit velocity %2 deg/min on modulo axis %1 has been exceeded (incorrect cam output)
Parameters:
%1 = Axis, spindle
%2 = Limit velocity
Explanation:
Reliable cam output on the modulo axis can no longer be assured.
This is because:
The velocity of the axis exceeds the permissible velocity range
Reliable calculation of the cam output on the modulo axis
can only be assured below the limit speed
Reaction:
Alarm display.
Remedy:
- Reduce the traversing speed of the axis
- Alarm can be suppressed with SUPPRESS_ALARM_MASK_2 bit 15

Axis %1 minimum cam width cam %3 undershot at curr. velocity %2
Parameters:
%1 = Axis, spindle
%2 = Limit velocity
%3 = Cam number
Explanation:
The width of the cam signal undershoots the time t=50µs and as a result can no longer be output.
This is because:
The cam signal width of t=50µs must not be undershot.
A configured cam width and reliable time results in
a limit velocity for the cam (v=s/t). If the limit velocity is exceeded,
cam signals will be lost.
Reaction:
Alarm display.
Remedy:
- Reduce the traversing speed of the axis
- Increase the cam width
- Alarm can be suppressed with SUPPRESS_ALARM_MASK_2 bit 15
