Copy Error

SEW Eurodrive · MOVIFIT SC

What does 97 mean?

This fault indicates an error occurred during a data transmission or copying process within the unit, possibly when transferring parameters, firmware, or application-specific data. This could lead to incomplete or corrupted data, potentially affecting the unit's functionality, causing it to operate with incorrect settings, or failing to load a new configuration. It might be due to transient memory issues or an interrupted copy procedure, and can result in unreliable operation.

Common Causes

  • Intermittent communication bus (e.g., RS485, Ethernet/IP) error during parameter upload/download or firmware update due to noise, impedance mismatch, or cable integrity issues.
  • Incompatible firmware version being loaded onto the unit, leading to data structure conflicts during the copying process.
  • Corrupted source file (e.g., firmware .bin file, parameter .csv file) being used for the data transfer, resulting in write errors.
  • Temporary internal processor error or watchdog reset occurring during the critical data writing phase.
  • Insufficient memory space on the target device for the incoming data, although modern devices usually pre-check this condition.

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Re-attempt the data copying or firmware update process using a known-good, verified source file obtained directly from the manufacturer's website.

  2. 2

    Inspect the communication cable (e.g., USB-to-RS485, Ethernet patch cable) for physical damage, proper termination (e.g., 120 Ohm resistor), and secure connections.

  3. 3

    Verify the communication settings (e.g., baud rate, parity, stop bits) on both the source device (e.g., PC) and the target unit (e.g., P7-01 "Comm Baud Rate") match precisely.

  4. 4

    Power cycle the unit completely (turn off main supply, wait 30 seconds, turn on) before attempting another data transfer.

  5. 5

    If using a memory card (e.g., SD card) for parameter transfer, try a different, known-good memory card formatted according to manufacturer specifications (e.g., FAT32).

  6. 6

    Check the firmware compatibility matrix provided by the manufacturer to ensure the intended firmware version is correct for the specific hardware revision of the unit.
