Overview of Alarms
NCK alarms
15025 CHANDATA(%2): channel is not active. Channel data will be ignored.
Parameters: %1 = Channel number
%2 = CHANDATA parameter
Definitions: With a CHANDATA instruction, the data input for a channel is selected that has not been activated.
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
Remedy: This is an informational alarm referring to the fact that the file loaded into the NCK contains data of an
inactive channel. The number of the inactive channel is specified. Subsequently, the data of this
channel are not available in the NCK.
The alarm may have two causes:
(1) The channel is supposed to be activated by a following NCK RESET/POWER ON, i.e. the file must
subsequently be reloaded.If the alarm occurs again, the reason is: (2) the specified channel is actually
not supposed to be activated, however, the file contains the relevant data.
For the 2nd reason, please check whether the system has correctly not activated the channel
mentioned.
If the channel has been activated, operation may be continued after another NCK RESET/POWER
ON without further measures, i.e. reloading the file is not required. If the channel has not been
activated, make sure that the channel inactivated by mistake is re-activated.
If the settings of the channel activation are part of the file to be loaded (e.g. archive file), the file must
either be modified with the relevant program or the file has to be created once more in the same
system with the correct channel number.
Similar alarms: 15020, 15021.
Program Switch control OFF - ON.
Continuation:
15030 Channel %1 block %2 different measurement system settings
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: The INCH or METRIC instruction describes the system of measurement in which the data blocks have
been read from the control. In order to prevent the incorrect interpretation of data intended for a
particular system of measurement, a data block is only accepted if the above instruction matches the
active system of measurement.
Reaction: Interpreter stop
NC Start disable in this channel.
Interface signals are set.
Alarm display.
Remedy: Change the system of measurement or load a data block which matches the system of measurement.
Program Clear alarm with the RESET key. Restart part program
