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. 1

    Measure the resistance of the temperature sensor element at ambient temperature.

  2. 2

    Inspect the temperature sensor cable for breaks or damage.

  3. 3

    Verify the sensor type (e.g., NTC, PTC, PT100) matches parameter P1-07.

  4. 4

    Ensure the temperature sensor connector is securely plugged into the amplifier.

  5. 5

    Apply gentle heat to the sensor and monitor resistance change.
