Memory module: wrong type

Lenze · i550 Protec Drive

What does 30346 mean?

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

Common Causes

  • 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.
