Function
0
Low
Operates when the motor overheat sensor input is
smaller than PRT-36.
1
High
Operates when the motor overheat sensor input is
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
Wnen the AO 2 (analog current outout) 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 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‘.
