Code Description
PRT-34
Thermal-T Sel
Sets the inverter operation state when motor is overheated.
Setting Function
0 None Do not operate when motor overheating is detected.
1 Free-Run
When the motor is overheated, the inverter output is
blocked and the motor will free-run by inertia.
3 Dec
When the motor is over heated, the motor decelerates
and stops.
PRT-35
Thermal In Src
Selects the type of the terminal when the motor overheat protect sensor is
connected to the volt (V1) or current (I2) input terminal of the terminal block
in the inverter.
Setting Function
0 Thermal In
Configure the motor overheat protect sensor
connection to terminal block V1.
1 V2 Configure the motor overheat protect sensor
