官方故障排除步驟
Parameters: %1 = Channel ID Definitions: Informational alarm. The search run was not performed on the interrupti on block, instead, it touches down shortly before that. This so-called "hol d block" is generated by the part progr am command IPTRLOCK, or implicitly defined by MD22680 $MC_AUTO_IPTR_LOCK. This is to prevent you from performing a search run in critical program areas (e.g. gear hobbing). The al arm also displays that, instead of searching for the block that actually was interrupted before, anot her block is being searched for. This behavior is desired and the alarm serves only informational purposes. Reaction: Alarm display. Remedy: MD11410 $MN_SUPPRESS_ALARM_MASK, MD22680 $MC_AUTO_IPTR_LOCK and language command IPTRLOCK Program Continuation: Clear alarm with the Delete key or NC START.
