H10

Was bedeutet 110 ?

The sensor for detecting the heatsink temperature is indicating undefined values. This suggests a fault with the sensor or its connection, leading to unreliable temperature monitoring.

• Heatsink temperature sensor (e.g., NTC thermistor, PT100) has failed internally or is physically damaged.
• Wiring harness from the heatsink sensor to the main control board (e.g., X12 connector) is loose, disconnected, or corroded.
• Input circuit on the control board responsible for reading the heatsink temperature sensor has malfunctioned.
• High levels of electrical noise on the sensor signal lines due to insufficient shielding or improper cable routing near power conductors.

1. 1

   1. Power down the drive and visually inspect the heatsink temperature sensor element and its connecting wires for damage.

2. 2

   2. Measure the resistance of the heatsink temperature sensor element at ambient temperature and compare it to the manufacturer's specified resistance curve (e.g., 10 kOhm at 25°C).

3. 3

   3. Verify continuity of the heatsink temperature sensor wiring from the sensor to the drive's control board connector (e.g., X12) using a multimeter.

4. 4

   4. Reseat the temperature sensor connector on the main control board to ensure proper electrical contact.

5. 5

   5. Isolate the temperature sensor wiring from potential sources of electromagnetic interference (EMI) and ensure proper cable shielding is maintained.
