The Siemens 6SL3255-6AA00-5AA0 is the G120P-SAM Smart Access Module for the SINAMICS G120P drive family. It provides a local operator interface and commissioning access point on the drive front panel, allowing parameter read/write, diagnostics, and basic control without a connected PC or fieldbus master. The module mounts directly onto the G120P Control Unit, occupying the slot intended for the Smart Access Module. No separate wiring or power supply is needed — it draws its operating power from the Control Unit backplane.
Packaging unit is 1, so each order code delivers a single Smart Access Module in its own box.
