Siemens 17500 - Block axis is not an indexing axis

Block axis is not an indexing axis

An indexing axis position has been programmed for an axis with the keywords CIC, CAC or CDC that has not been defined as indexing axis in the machine data Control reaction: Correction block is reorganized. Interface signals are set. Alarm display.

Safety

  • Only qualified personnel should diagnose and clear control alarms; follow the machine builder's safety procedures and lockout/tagout where hardware work is required.

Common Causes

  • An indexing axis position has been programmed for an axis with the keywords CIC, CAC or CDC that has not been defined as indexing axis in the machine data

Troubleshooting Steps

  1. 1Please inform the authorized personnel/service department.
  2. 2Remove programming instruction for indexing axis positions (CIC, CAC, CDC) from the NC part program or declare the relevant axis to be an indexing axis.
  3. 3Indexing axis declaration: Modify MD30500: $MA_INDEX_AX_ASSIGN_POS_TAB (indexing axis assignment) The axis will become an indexing axis when an assignment to an indexing position table was made in the stated MD.
  4. 42 tables are possible (input value 1 or 2).
  5. 5Modify MD10900 $MN_INDEX_AX_LENGTH_POS_TAB_1 Modify MD10920 $MN_INDEX_AX_LENGTH_POS_TAB_2 (Number of positions for 1st/2nd indexing axis) Standard value: 0 Maximum value: 60 Modify MD10910 $MN_INDEX_AX_POS_TAB_1 [n] Modify MD10930 $MN_INDEX_AX_POS_TAB_2 [n] (Positions of the 1st indexing axis) The absolute axis positions are entered. (The list length is defined via MD10900 $MN_INDEX_AX_LENGTH_POS_TAB_1).
  6. 6Clear alarm with NC START or RESET key and continue the program. Continuation: Alarms
