問題描述與安全警告
Siemens SINUMERIK 840D CNC 觸發了嚴重的 [Channel %1: ] Block %2 curve table %3: NC me mory limit DRAM reached type %4. 警報。需要由合格的操作員或維修技師立即處理,以防止在製造週期中對設備造成二次損壞或導致零件報廢。在接觸電氣控制箱之前,請務必確保遵循標準安全和停機掛牌 (LOTO) 程序。
官方故障排除步驟
Parameters: %1 = Channel number %2 = Block number, label %3 = Number of curve table %4 = Object type Definitions: Insufficient memory in the DRAM while defining the curve table. The object type parameter specifies for which curve table object the memory will not suffice: 1: Number of curve tables too small (MD18406 $MN_MM_NUM_CURVE_TABS_DRAM) 2: Number of linear curve table segments too small (MD18409 $MN_MM_NUM_CURVE_SEG_LIN_DRAM) 3: Number of polynomial curve table segments too small (MD18408 $MN_MM_NUM_CURVE_SEGMENTS_DRAM) 4: Number of curve table polynomials too small (MD18410 $MN_MM_NUM_CURVE_POLYNOMS_DRAM) Reaction: Interpreter stop NC Start disable in this channel. Interface signals are set. Alarm display. Remedy: Delete the curve tables that are no longer require d in DRAM or reconfigure the memory space for the curve tables. The curve table must then be redefined. Machine data for memory configuration of the curve tables in DRAM: MD18406 $MN_MM_NUM_CURVE_TABS_DRAM, MD18408 $MN_MM_NUM_CURVE_SEGMENTS_DRAM, MD18409 $MN_MM_NUM_CURVE_SEG_LIN_DRAM, MD18410 $MN_MM_NUM_CURVE_POLYNOMS_DRAM. Program Continuation: Clear alarm with the RESET key. Restart part program
