Overview of alarms
NCK alarms/ISO alarms
26051
Channel %1 in block %2 unanticipated stop crossed in continuous path
mode
Parameters:
%1 = Channel number
%2 = Block number, label
Definitions:
The path interpolation did not stop, as required, at the end of the block, but will only decelerate to a
standstill in the next block. This error situation occurs if the stop at block change was not planned by
the path interpolation or was not detected early enough. A possible cause is that the PLC changed the
spindle speed when $MA_SPIND_ON_SPEED_AT_IPO_START > 0, and the machine has to wait
until the spindle has returned to the setpoint range. Another possible cause is that a synchronized
action needs to be finished before the path interpolation continues. The alarm is only output if
$MN_TRACE_SELECT = 'H400'. The alarm output is normally suppressed. - $MN_TRACE_SELECT
has SIEMENS password protection.
Reaction:
Alarm display.
Remedy:
$MA_SPIND_ON_SPEED_AT_IPO_START = 1. Program G09 before the alarm output in the block
to allow the path interpolation to stop as planned.
Program Continuation:
Clear alarm with the Delete key or NC START.
26052
Channel %1 in block %2: path velocity too high for auxiliary function
output
Parameters:
%1 = channel number
%2 = block number, label
Definitions:
This alarm usually occurs in a block with auxiliary function output during a movement. In this case, the
wait for acknowledgement of the auxiliary function was longer than planned.
The alarm occurs if internal control inconsistencies cause continuous path mode (G64, G641, ...) to
be blocked unexpectedly.
The path interpolation stops abruptly at the end of the block indicated in the message (regenerative
stop). On the next block change, the path continues unless the abrupt stop has caused an error in the
position controller (e.g. because the MD 36400 CONTOUR_TOL setting was over-sensitive).
Reaction:
Alarm display.
Remedy:
Program G09 in the block indicated in the message to allow the path interpolation to stop as planned.
Program Continuation:
Clear alarm with the Delete key or NC START.
26070
Channel %1 axis %2 cannot be controlled by the PLC, max. number
exceeded
Parameters:
%1 = channel number
%2 = axis name, spindle number
Definitions:
An attempt has been made to control more axes than allowed from the PLC.
Reaction:
Interface signals are set.
Alarm display.
Remedy:
Check the machine data MD_NUM_MAX_PLC_CNTRL_AXES and correct if necessary or reduce the
number of PLC-controlled axes.
Program Continuation:
Clear alarm with the Delete key or NC START.
26072
Channel %1 axis %2 cannot be controlled by the PLC
Parameters:
%1 = channel number
%2 = axis name, spindle number
Definitions:
The axis cannot be made a PLC-controlled axis. For the time being, the axis cannot be controlled at
any state from the PLC.
Reaction:
Interface signals are set.
Alarm display.
Remedy:
Use Release or Waitp to make the axis a neutral one.
Program Continuation:
Clear alarm with the Delete key or NC START.
