Incompat C-P

What does F106 mean?

The PowerFlex 525 control module has been paired with a power module that has an incompatible 0.25 HP power rating, which it does not support. This is a fundamental hardware mismatch between the control and power sections, preventing proper operation.

• A PowerFlex 525 control module is paired with a power module whose nameplate indicates a 0.25 HP rating, which is not supported by the 525 series.
• Incorrect power module was physically installed with a PowerFlex 525 control module (e.g., mixing PowerFlex 523 power section with 525 control).
• The power module's internal identification (ID) chip or circuitry is reporting an incorrect or corrupted HP rating to the control module.
• Firmware mismatch where the control module's firmware does not properly recognize the ID of certain power module variants.
• Damage to the communication interface between the control module and the power module, causing misinterpretation of the power module's ID.

Click steps to track your progress.

1. 1

   1. Verify the exact catalog number and HP rating on the nameplate of the power module against the specifications for the PowerFlex 525 drive series.

2. 2

   2. Ensure the installed power module is indeed a PowerFlex 525 series power module and not a different PowerFlex 500 series variant (e.g., 523, 527).

3. 3

   3. If the power module is confirmed to be incorrect, replace it with a compatible PowerFlex 525 series power module of the correct HP rating.

4. 4

   4. Power down the drive, remove the control module, inspect its connectors for damage, and re-seat it firmly onto the power module.

5. 5

   5. Record the firmware revision of the control module and check for any manufacturer bulletins regarding power module compatibility issues.
