官方故障排除步驟
Parameters: %1 = Channel number %2 = Block number Definitions: The language functions WAITMC, SETM, CLEARM and MSG must be packed in separate NC blocks due to the language definition. To avoid velocity dr ops, these blocks are attached to the next NC block internally in the NCK (for MSG only in path contro l mode, for WAITMC to the previous NC block). For this reason, there must always be an executable block (not a calculation block) between the NC blocks. An executable NC bl ock always includes e.g. travel move ments, a help function, Stopre, dwell time etc. Reaction: Correction block is reorganized. Interpreter stop Interface signals are set. Alarm display. Remedy: Program an executable NC block between th e previous and the current NC block. Example: N10 SETM. N15 STOPRE; insert executable NC block. N20 CLEARM. Program Continuation: Clear alarm with NC ST ART or RESET key and continue the program.
