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
- The maximum permissible number of blocks with active compensation suppression with tool radius compensation is limited by MD20252 $MC_CUTCOM_MAXNUM_SUPPR_BLOCKS
Troubleshooting Steps
- 1Modify part program.
- 2Modify machine data.
- 3Check whether SBL2 is activated.
- 4With SBL2, a block is generated from each part program line which can lead to exceeding the maximum permissible number of empty blocks between two traversing blocks.
- 5Clear alarm with NC START or RESET key and continue the program
