SP0006
Temperature Sensor Disconnected
Fanuc · AC Spindle Motor Alpha i-Beta i Series Parameters
What does SP0006 mean?
The temperature sensor connected to the spindle amplifier is disconnected. This prevents accurate monitoring of motor temperature, leading to a potential overheat risk.
Common Causes
- Temperature sensor (thermistor or RTD) disconnected from the amplifier.
- Break in the sensor's wiring harness.
- Faulty temperature sensor itself.
- Incorrect sensor type configured in amplifier parameters.
- Connector pin failure for the temperature sensor input.
Repair Steps & Checklist
Click steps to track your progress.
- 1
Measure the resistance of the temperature sensor element at ambient temperature.
- 2
Inspect the temperature sensor cable for breaks or damage.
- 3
Verify the sensor type (e.g., NTC, PTC, PT100) matches parameter P1-07.
- 4
Ensure the temperature sensor connector is securely plugged into the amplifier.
- 5
Apply gentle heat to the sensor and monitor resistance change.
