What is the nominal resistance of the NTC thermal sensor for the Altivar ATV66 Size 6 or size 7 drive at room temperature?

The simplest way to test the sensor is to simply look at the drive thermal state on the display. At room temperature (70 F or 21 C), the drive thermal state is about 20 %.
The NTC probe will have about 100 K Ohms resistance at room temperature of 70 degrees Fahrenheit (21 degrees C).
Do not measure Ohms for the probe while it is still connected to the power board. Test the sensor out of the circuit for best results.
