When replacing the motherboard in a Siemens inverter during maintenance, it's important to note that the motherboard contains microprocessors and memory chips that store critical program data. Therefore, it is recommended to replace the motherboard with one from a Siemens inverter of the same model and power rating. However, after replacement, some parameters may need to be adjusted before the inverter can function properly.
Compared to other Siemens inverters of the same model and power, not all units will automatically restore their factory settings after a motherboard replacement. In some cases, especially when only a limited number of parameters can be read or when factory values cannot be restored, manual parameter adjustment becomes necessary. This process ensures that the inverter operates correctly and safely.
To reset the parameters after replacing the motherboard, follow these steps:
1. Access the inverter menu by setting P0003 to level 3 (user access).
2. Navigate to parameter R200 and record its value.
3. Check parameter P201 and compare it with R200. If they don’t match, adjust P201 to match R200.
4. Set P0010 to 30, which initiates the factory configuration mode.
5. Finally, set P970 to 1. Press Enter, and the inverter will begin restoring factory settings.
6. The process typically takes about 30 seconds. Once completed, the inverter should start up normally.
This method helps ensure that the inverter functions as intended after the motherboard has been replaced. It’s always a good idea to double-check all parameters and test the system thoroughly after any major component replacement.
If you're unsure about the process or encounter issues, consult the official Siemens documentation or contact a certified technician for assistance. Proper parameter setup is crucial for the safe and efficient operation of the inverter.
