PR3 (Checksum error in parameter set 3)

Hva betyr 0077 ?

A checksum error has been detected in parameter set 3, indicating a fault during loading or an interruption during transfer via the keypad. This can also occur if saved parameters are incompatible with the loaded software version.

• Interruption of parameter transfer (e.g., during upload from keypad or communication bus) to parameter set 3.
• Data corruption in the non-volatile memory bank corresponding to parameter set 3.
• Attempting to load a parameter set 3 that was created on an older or incompatible firmware version.
• Power loss or voltage fluctuation during the save operation for parameter set 3.
• Faulty keypad or communication interface transmitting incorrect data for parameter set 3.

1. 1

   Cycle power to the drive and attempt to reload parameter set 3 from a known good backup file using the appropriate software tool.

2. 2

   Verify the integrity of the parameter set 3 file used for transfer and ensure it matches the current firmware version (C0004).

3. 3

   If transferring via keypad, ensure a stable connection and retry the transfer of parameter set 3, monitoring for interruptions.

4. 4

   Set C0003 to 1 (factory default) to clear any corrupted settings, then carefully reconfigure only the necessary parameters in set 3.

5. 5

   Check the drive's communication bus (e.g., CAN, EtherCAT) for noise or intermittent connections if parameter set 3 transfer occurs over the bus.
