Sinumerik Alarm 14156 Channel %1 toolholder selection error at reset
%1 = Channel number
The settings in RESET_MODE_MASK require that an active orientable toolholder is maintained after the reset. This is done by deselecting the old orientable toolholder and then reselecting it with data that may have been modified. If an error occurs during the reselection, this alarm is issued (as a warning) and then an attempt is made to select the orientable toolholder in the initial setting. If this second attempt is successful, the reset cycle is continued without any further alarms.
Typically, the alarm only occurs when the old orientable toolholder has been selected with TCOFR, and its axis directions have been changed in such a way before the reset that a setting suitable for the associated frame is no longer possible. If there is another cause for the alarm, this results in an alarm also being issued when attempting to select in the initial setting. This is then also displayed in plain text.
