Thermistor Error

What does E35. mean?

This fault occurs when the inverter detects an abnormal temperature, indicated by a resistance value of 3 kΩ or more from an external thermistor connected to the TH input terminal. This suggests the motor temperature is too high, or there's a fault in the thermistor itself or its wiring, preventing accurate temperature monitoring.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Verify the thermistor wiring for correct connection and ensure it is separated from power cables to avoid noise interference.

2. 4

   Adjust the Thermistor Adjustment (C085) parameter if the trip threshold needs to be recalibrated for the application.
