5-3. Motor Temperature Detection (PTC)
Frequency inverter has a motor temperature sensor input (PTC input : PTC resistor).
When the resistance value is more than 3k ohm +-10%, the frequency inverter trips with “E35”.
5-4. Over Temperature Detection of the Frequency Inverter
Frequency inverter has a temperature detection against power devices of the main circuit. Frequency
inverter shuts down the output when temperature around IGBT comes up to 120 degree C.
