Using PTC resistors
PTCs are suitable for temperature monitoring and as thermal protective devices for complex
drives and transformer windings.
● Select "Two-wire resistor" and "PTC" at parameter assignment:
● Connect the PTC in accordance with the two-wire connection method.
● Apply PTC resistors of Type A (PTC thermistors) in accordance with DIN / VDE 0660,
● If the diagnosis "Overrun/underrun" is enabled, a diagnosis "Lower limit exceeded"
● Sensor data for the PTC resistor:
