Siemens 16120 - Block invalid index for tool fine compensation

Mistake in programming: The 2nd parameter in the PUTFTOC command indicates for which tool parameter the value is to be corrected (1 - 3 tool lengths, 4 tool radius). The programmed value is beyond the permitted range. Permissible values are 1 - 4 if on-line tool radius compensation is allowed (see MD20254 $MC_ONLINE_CUTCOM_ENABLE), otherwise values 1 - 3 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

  • Mistake in programming: The 2nd parameter in the PUTFTOC command indicates for which tool parameter the value is to be corrected (1 - 3 tool lengths, 4 tool radius).
  • The programmed value is beyond the permitted range.
  • Permissible values are 1 - 4 if on-line tool radius compensation is allowed (see MD20254 $MC_ONLINE_CUTCOM_ENABLE), otherwise values 1 - 3

Troubleshooting Steps

  1. 1Modify part program: Length 1 - 3 or 4 permissible for radius.
  2. 2Clear alarm with NC START or RESET key and continue the program
