ST600s | Connection of a temperature sensor

P00.01 1 Terminal control active
P05.04 57 S4 = Error input, motor temperature too high
P06.03 50 Relay output RO1 = AI/AO motor temperature alarm
P06.14 32 AO1 = AI/AO temperature contact input
P28.25 4 Sensor type = PTC (Resistance measurement only)

 

If the value 4 is not displayed in parameter P28.25, the display language must be set to English. If the value 4 has been successfully configured, the display language can be switched back to German without affecting the parameter value.

To connect a PTC to the inverter, the following terminals must first be bridged: AO1 to AI1, +24V to RO1C, RO1A to S4.
One pole of the PTC is connected to terminal AO1 or AI1, and the other pole of the PTC is connected to terminal GND.
Additionally, switch SW2 on the board must be set to “I” (current).
