The 6SL3255-0AA00-4JA2 is the SINAMICS IOP-2 — the intelligent operator panel for local commissioning, monitoring, and diagnostics of G120-series drives. It plugs directly into the Control Unit and draws power from the drive — no separate supply needed. A color graphical LCD with membrane keypad gives you plain-text fault messages, guided startup wizards, and one-touch parameter set cloning between drives.

What can the IOP-2 do that the basic BOP cannot?

The IOP-2 adds a color screen, plain-text diagnostics (no blinking codes to decode), QR code scanning for instant access to product documentation via the Siemens Industry Online Support app, and a virtual keyboard for direct parameter entry. It supports 14 languages and can clone complete parameter sets between drives — a major time-saver during multi-drive commissioning.

How is it mounted?

Three options: snap directly onto the Control Unit for bench setup, install in a cabinet door with the IP55 door-mount kit (6SL3256-0AP00-0JA0), or use the handheld kit (6SL3255-0AA00-4HA1) for mobile operation with battery power.
