Goodrive350-19 Series VFD for Crane
1. Connect the PTC according to Figure 5-23 Wiring between PTC and analog terminals.
2. Set P92.22=4 to set the temperature sensor type to PTC.
3. Set P06.23 (often using the default value).
4. Set P06.24 and P06.25 according to the selected PTC model resistance and temperature curve.
5. Check whether the actual PTC resistance is correct.

0.000–20.000mA
0–60000Ω
When P06.26 is greater than P06.24, the VFD
reports the alarm A-Aot and the system runs
normally.
0–60000Ω
When P06.26 is less than P06.25, the alarm A-Aot is
cleared.
