Temperature sensor fault

What does F07016 mean?

A temperature sensor fault has been detected. This fault is output if alarm A07015 (temperature sensor fault) persists beyond the timer set in p0607, after at least 1 second. The fault value (r0949) indicates the number of the sensor channel that triggered the message.

• Temperature sensor element failure (e.g., RTD open circuit, NTC thermistor short circuit, thermocouple junction corrosion).
• Sensor wiring fault (e.g., cable break, loose connection at X1 or X2 terminals, shielding damage causing interference).
• Incorrect parameterization of sensor type (e.g., P0600) or monitoring limits (e.g., P0604, P0605) for the connected temperature sensor.
• Measurement circuit fault on the drive or module (e.g., analog input module failure, internal processing error).
• Excessive ambient temperature exceeding the sensor's operating range (e.g., due to inadequate cabinet cooling, blocked airflow).

Click steps to track your progress.

1. 1

   1. Measure the resistance of the temperature sensor directly at its terminals, comparing the value to the sensor's datasheet for the current ambient temperature.

2. 2

   2. Check continuity of sensor wiring from the sensor to the drive input terminals (e.g., X1 or X2) using a multimeter, checking for insulation resistance to ground.

3. 3

   3. Verify drive parameters P0600 (Sensor type), P0601 (Number of sensors), P0604 (Warning threshold), and P0605 (Fault threshold) match the installed sensor and application.

4. 4

   4. Temporarily connect a known good, calibrated temperature sensor to the drive input and monitor r0035 (Actual temperature value) for correct readings.

5. 5

   5. Inspect the cooling system of the cabinet or motor for proper operation (e.g., fan functionality, clean filters) and measure internal cabinet temperature.
