Sinumerik Alarm 15025 CHANDATA(%2): channel is not active. Channel data will be ignored.
%1 = Channel number
%2 = CHANDATA parameter
With a CHANDATA instruction, the data input for a channel is selected that has not been activated.
– Alarm display.
– Interface signals are set.
– NC Start disable in this channel.
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 second 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.
Switch control OFF – ON.
