Common Causes

• Spindle load during cutting exceeded the breakage detection threshold set in tool offset page or Setting parameters
• Tool breakage detection probe cycle detected missing tool length or diameter outside tolerance window after machining operation
• Incorrect breakage detection sensitivity settings causing false triggers from normal cutting loads or vibration
• Actual tool breakage occurred due to excessive feedrate, incorrect speeds, worn tool, or hard material inclusion
• Wiring or signal issues between tool setter probe and IOCON causing erroneous breakage detection signal

Troubleshooting Steps

1. 1Step 1: Inspect tool in spindle visually for actual breakage - remove and measure if necessary to confirm physical condition
2. 2Step 2: Access OFFSET page and review tool breakage detection parameters for the affected tool number, verify thresholds are realistic
3. 3Step 3: If using load-based detection, review spindle load monitor values in Diagnostics page during test cut to establish proper threshold
4. 4Step 4: If using probe-based detection, manually run tool setter cycle and verify probe triggers correctly and tool dimensions read accurately
5. 5Step 5: Check Setting 78 and related tool breakage settings to ensure detection mode and sensitivity match machine configuration and tooling
6. 6Step 6: Review machine history for pattern of false alarms - adjust detection parameters upward or disable feature if not required for production
