Error code E5446 means a EEPROM checksum error on power fail data. This error comes when the 24 VDC fails during
the EEPROM save process. In some cases, it has been observed to happen after a firmware update. To recover from this
error, perform a reset to factory settings and cycle 24V supply to the drive. If the error is still on, repeat the firmware update
procedure followed by a reset to factory settings and then cycle 24V supply again.
