How to adjust the power rating of ABB’s ACS510/ACS550/ACS350/ACS355/ACH550 VFDs

With ABB’s ACS510/ACS550/ACS350/ACS355 VFDs, you can easily adjust the power rating through a straightforward process. Whether you want to upgrade a 1.1KW VFD to 5.5KW or vice versa, this flexibility allows you to set the power rating according to your needs. This feature is particularly useful when you have a limited number of VFD main boards, such as SMIO-01C, and need to adapt them to different power ranges. With this adjustment, you can ensure seamless operation even if a VFD in a different power range fails. These are not mentioned in the ABB AC drives PDF manual

1. How to access and modify parameters:
   Open the parameter table, navigate to the deepest level of parameters, such as 0102, or any other displayed parameters. For example, if it says 9905, then hold the UP (arrow up), DOWN (arrow down), and RETURN (the button on the upper left next to LOC) buttons simultaneously for 3 seconds. You will notice a flash on the screen, and the top line of the screen should show “PARAMETERS+”.
2. Expanding parameter groups:
   After that, exit and re-enter the parameter groups. Now, you will notice that the number of parameter groups has expanded from the original 99 to a maximum of 120. Navigate to parameter group 105.
3. Modifying power capacity:
   To modify the relevant power capacity, follow these steps:
   • Find and modify parameter 10509. Change 105.09 to the desired current value and modify the corresponding power value accordingly (make sure it matches theVFD label. For example, if your inverter model is ACS510-01-017A-4, change it to 0174H; for ACS510-01-031A-4, change it to 0314H).
   • Set 10502 to 1 and confirm.
   • Set 10511 to 4012 and confirm.
   Please note that the order of modifications is crucial. If you make a mistake, you may need to start over.
4. Verifying parameter changes:
   Finally, re-enter the parameter table and check if parameter 3304 (transmission capacity) has been correctly modified.

Just a reminder, the process of changing the power above has only been changed to the power of the ABB drive motherboard(SMIO-01C). The power of the drive board has not been changed, although it shows that it can be expanded. In fact, if the power of the power board has not been changed, the actual output power of the variable frequency drive (VFD) has not changed. At the same time, this method is only applicable to ACS510/ACS550/ACS350/ACS355/ACH550 VFDs and is not suitable for ACS800 series inverters. If you would like to know the power modification method for ACS800 inverters, please contact us directly.
