User set fault

ACS880 · Primary Control Program Firmware

What does 64B2 mean?

Loading of a user parameter set failed in the ACS880 drive. This can happen if the requested parameter set does not exist, is incompatible with the control program, or if power was lost during the loading process.

Common Causes

  • The requested user parameter set does not exist in the drive's memory or on the connected storage device.
  • The user parameter set is incompatible with the drive's current control program firmware version.
  • The drive was switched off or experienced a power interruption during the loading process, corrupting the parameter set.
  • The user set itself is corrupted or contains invalid parameter values.

Repair Steps & Checklist

  2. 2

    Verify that the user parameter set is compatible with the drive's current firmware version; update firmware or modify the set if incompatibility is found.

  3. 3

    If a power interruption occurred, retry the loading process carefully, ensuring a stable and uninterrupted power supply.

  4. 4
