ing

Motors that are equipped with a thermistor can be protected from overheating. Input 
terminal [5] has the unique ability to sense a thermistor resistance. When the resistance 
value of the thermistor connected to terminal [TH] (5) and [L] is more than 3 k Ohms 
±10%, the inverter enters the Trip Mode, turns OFF the output to the motor, and 
indicates the trip status E35. Use this function to protect the motor from overheating.

Thermistor Thermal 
Protection

Sensor When a thermistor is connected to terminals [5] 

and [L], the inverter checks for over-temperature 
and will cause trip (E35) and turn OFF the 
output to the motor

Open

An open circuit in the thermistor causes a trip, 
and the inverter turns OFF the output

C_05 only

(none)

Be sure the thermistor is connected to terminals [5] 
and [L]. If the resistance is above the threshold the 
inverter will trip. When the motor cools down 
enough, the thermistor resistance will change 
enough to permit you to clear the error. Press the 
STOP/Reset key to clear the error.
