Params Defaulted

What does F48 mean?

This fault indicates that the drive has been commanded to restore its parameters to factory default values, typically through a user action or system command. While not a malfunction, it means previous custom configurations are lost, which could lead to incorrect operation if not re-programmed.

• Accidental initiation of a factory reset command via the drive's HMI or control software.
• External command received through a communication network (e.g., Modbus, Ethernet/IP) specifically requesting a parameter default.
• Internal non-volatile memory corruption requiring the drive's firmware to default parameters (rare).
• Replacement of the drive's control board without a proper parameter backup and restore procedure.

Click steps to track your progress.

1. 1

   Identify the method by which parameters were defaulted (e.g., HMI button sequence, network command, specific parameter setting like P1-05).

2. 2

   Upload a previously saved parameter configuration file from backup software to restore settings to the drive.

3. 3

   If no backup exists, manually re-enter all critical motor and application parameters (e.g., P3-08, P3-09, P3-10, P3-11).

4. 4

   Review security settings or user access levels to prevent unauthorized parameter changes or resets.

5. 5

   Perform a full functional test of the drive and connected equipment after parameters are restored and saved.
