● The ambient temperature also affects the derating. See Section 9-7-1 Derating Curve for Ambient Temperature
and Altitude.
● Take RT-005X-43N in normal load as an example: ambient temperature 50°C, UL open-type, and independent
installation. When the carrier frequency is set to 10 kHz, it corresponds to 55% of the rated output current. If
used for ambient temperature 60°C, it corresponds to 55% * 75% of the rated output current.

PT100 operation instructions:
1. Use voltage type analog input (AVI, ACI voltage 0–10 V) and select PT100 mode.
2. Select one of the voltage type analog inputs below:
(a) Pr.03-00 =11, (b) Pr.03-01 = 11 and Pr.03-29 = 1
3. When selecting Pr.03-01 = 11 and Pr.03-29 = 1, you must switch AFM to 0–10 V.
4. The AFM outputs constant voltage or current, then Pr.03-20 = 23. You must switch ACM to 0–20 mA, and set
AFM output level to 45% (Pr.03-32 = 45%) of 20 mA = 9 mA.
5. Use Pr.03-32 to adjust the constant voltage or constant current of the AFM output; the setting range is 0.00–
100.00%.
6. There are two types of action levels for PT100. The diagram below shows the PT100 protection action.

When Pr.06-58 = 0.00 Hz, PT100 function is disabled.
