Memory module: wrong type

Lenze · i550 Protec Drive

Was bedeutet 30346 ?

The connected memory module is not compatible with or supported by the inverter hardware. This prevents the inverter from operating with the module.

Häufige Ursachen

  • An incorrect type of memory module (e.g., EPM from a different drive series, manufacturer, or incompatible product family) has been inserted.
  • The inserted memory module is designed for a specific hardware revision or firmware family that is not compatible with the current inverter.
  • Physical damage to the memory module (e.g., bent pins) or to the inverter's memory module slot preventing proper electrical contact or identification.
  • Attempting to use a memory module designated for a specialized function (e.g., safety card, specific application module) in a standard drive or slot that does not support it.

    2. Carefully remove and reinsert the memory module, ensuring it is correctly seated and that there are no bent pins or foreign objects in the slot.

  3. 3

    3. Obtain a memory module that is explicitly listed as compatible with the inverter's exact model and firmware version, then insert it.

  4. 4

    4. Inspect the memory module slot on the inverter for any physical damage, debris, or corrosion that might interfere with proper recognition.

  5. 5

    5. Consult the inverter's technical manual or manufacturer's support to confirm the precise compatible memory module types for the installed hardware.
