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
terminals. (Use a thermistor with the PTC characteristics.)
•Trip level is fixed at 3 kΩ ±10% max.

19 PTC Thermistor input
Connected
When the thermistor is connected between terminals 5
and L, 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
