PRT-37
Thermal-T Area
Setting Function
0 Low
Operates when the motor overheat sensor input is
smaller than PRT-36.

bigger that PRT-36.
OUT-07 AO2 Mode,
OUT-08 AO2 Gain
Used when supplying the constant current to the temperature sensor and
receives input through the I2 or V1 terminal block by using the analog output
terminal.
Using the temperature sensor (PTC) by connecting it to the analog input terminal
When the AO2(analog current output) terminal is connected to the temperature sensor installed
on a motor, the inverter supplies constant current to the temperature sensor. Then, connecting the
motor signal wire to one of the inverter’s analog input terminals allows the inverter to detect the
changes in the PTC resistance and translates it into voltage. If the I2 terminal is used to receive the
signal, set the selection switch on the I/O board to V2. If the V1 terminal is used, set the switch to
T1. The sensor does not operate if SW3 is set to’ V1’.
