What does SP0132 mean?
Communication between the spindle sensor and the spindle amplifier is not performed. This indicates a problem in the data transmission/reception path between these components, preventing normal operation and potentially leading to unexpected machine behavior.
Common Causes
- Discharge current exceeds the allowed limit.
- External load demanding too much current.
- Short circuit in the output stage or load.
- Faulty current sensing circuit.
Repair Steps & Checklist
Click steps to track your progress.
- 1
Verify the physical connection of the sensor cable between the spindle sensor and the spindle amplifier for proper seating.
- 2
Inspect the sensor cable for any signs of physical damage, kinks, or loose contacts on its connectors.
- 3
If the cable appears intact and securely connected, attempt to reset the alarm after ensuring the physical connection is stable.
- 4
If the alarm persists, replacement of the spindle sensor or the spindle amplifier may be necessary, as a component might be faulty (refer to page 13 for general component replacement advice).
