Overview of Alarms
NCK alarms
26018 Axis %1 setpoint output drive %2 used more than once
Parameters: %1 = Axis name, spindle number
%2 = Drive number
Definitions: A setpoint has been selected more than once. The machine data 30110
$MA_CTRLOUT_MODULE_NR contains the same value for different axes.
Reaction: Mode group not ready.
The NC switches to follow-up mode.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Please inform the authorized personnel/service department. Avoid dual assignment of the setpoint by
correcting 30110 $MA_CTRLOUT_MODULE_NR. Also check the selected bus type
$MA_CTRLOUT_SEGMENT_NR.
Program Switch control OFF - ON.
Continuation:
26019 Axis %1 encoder %2 measurement not possible with this controller
module
Parameters: %1 = NC axis number
%2 = Encoder number
Definitions: If the MD $MN_DRIVE_DIAGNOSIS[8] contains a value not equal to zero, then the control has found
at least one control module which does not support measuring. Measuring was programmed from the
part program for the associated axis.
Reaction: Local alarm reaction.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: If possible, modify the measuring motion such that the axis concerned does not have to travel; do not
program this axis in the MEAS block again. However, it is then no longer possible to query a measured
value for this axis. Otherwise, exchange the controller module for one that supports measuring. See
MD $MN_DRIVE_DIAGNOSIS[8].
Program Clear alarm with the RESET key. Restart part program
