Motor Overheat Sensor Input Details
Code Description
PRT-34 Thermal-T
Sel
The inverter operating status is set when the motor overheats. If Free-Run
(1) is set, the inverter output will be blocked. If decelerating stop (2) is set
and the overheat sensor detects overheating, the inverter will decelerate
and stop.
PRT-35 Thermal In

The terminal type is selected when the motor overheat sensor is connected
to the voltage (V1) or current (I1) input terminals of the inverter terminal
block in the inverter. The voltage (V2) or current (I2) terminals in the I/O
expansion module are also available.
If you use the current input terminal I1 by supplying constant current to the
temperature sensor with the analog current output (AO2) terminal, the
switch in the I/O expansion module should be where the PTC is. Before use,
check if the switch is at the PTC.
[With voltage (V1) input] [With current (I1) input terminal]
Temperature is measured by letting a certain amount of current flow
through the A02 terminal and converting it into voltage depending on the
resistance value change.

You can set the overheat trip function input using the multi-function
terminal block input when using a bimetal-type sensor relay. Connect PTC
