Reset
This function resets an Inverter trip.
• You can also reset an Inverter trip by pressing the STOP/RESET key on the Digital Operator.
• In reset selection C102, you can select alarm reset timing and either enable/disable in normal
operation.
• For the RS terminal, only NO contact is available.
Thermistor Trip Function
This function protects the motor by tripping with the built-in thermistor detecting a temperature rise.
• Allocate 19 (PTC) to multi-function input 5 (C005). This cannot be used with other multi-function
inputs. (Use a thermistor with the PTC characteristics.)
• Trip level is fixed at 3 k
Ω
±10% max. For how to connect the thermistor, refer to "Functions of the
Control Circuit Terminals" (page 2-26).

19 PTC Thermistor input
Connected
When the thermistor is connected between terminals S5
and SC, the Inverter can detect motor temperature and,
if the temperature exceeds the specified level, trips to
shut off the output (E35). The level is fixed.
Open
If the thermistor is not connected, the Inverter trips (E35)
to shut off the output even with this function selected.
