Note: Turn SW2 on the control board to "I" for current output.
Procedure
1. Connect PT100/PT1000 according to Figure 5-21 Wiring between analog terminals and
PT100/PT1000.
2. Set P92.22=1 to select PT100, or set P92.22=2 to select PT1000.
3. Set P92.23 (AI detected motor OH protection threshold) and P92.24 (AI detected motor OH
pre-alarm threshold).
4. Check whether P94.20 (AI detected motor temperature) is correct.
