官方故障排除步骤
Parameters: %1 = Channel number Definitions: The settings in MD20110 $MC_RESET_MODE_MASK requir e that an active orientable toolholder is maintained after the reset. This is done by deselecti ng the old orientable toolholder and then reselecting it with data that may have been modified. If an er ror 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 rese t cycle is continued wit hout 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 anot her cause for the alarm, this results in an alarm also being issued when attempting to select in the init ial setting. This is then also displayed in plain text. Reaction: Alarm display. Remedy: Check the program. Program Continuation: Clear alarm with NC ST ART or RESET key and continue the program.
