The 6SL3255-0AA00-4CA1 is the SINAMICS BOP-2 — the basic operator panel for local setup, monitoring, and diagnostics of G120-series drives. It plugs directly into the Control Unit and draws power from the drive. A two-line backlit LCD with six tactile keys covers the essentials: parameter access, fault acknowledgement, manual/auto switching, and start/stop control.

BOP-2 or IOP-2 — which one do I need?

The BOP-2 handles the fundamentals: set parameters, monitor two process values at once, acknowledge faults, and clone parameter sets between drives. It does not have a color screen, guided startup wizards, or plain-text diagnostics — those are IOP-2 (6SL3255-0AA00-4JA2) features. Choose the BOP-2 when you need a rugged, low-cost panel for trained technicians who know the parameter numbers. Choose the IOP-2 for graphical commissioning, multilingual plain-text help, and QR-code support access.

Can parameter sets be copied between drives?

Yes. The BOP-2 stores a complete parameter set in its internal memory. Commission one drive, upload the parameters to the BOP-2, plug it into the next drive, and download — identical configuration in seconds. This works across all compatible G120 Control Units.
