Note: Temperature is displayed through P19.21. To
measure temperature, switch the output of AO1 to
current, and connect one end of the temperature resistor
to AI1 and AO1, and the other end to GND.

Note: When the motor temperature exceeds the value,
the DO terminal with function 48 (AI detected motor OH
pre-alarm) outputs a valid signal.
