The 6SL3230-3YE40-1AF0 is the F-suffix 55 kW G120X in the FSE frame — 3C3 coated with an integrated C2 EMC filter and no operator panel. Electrically identical to the 1AP0 at 149 A LO — the P and F suffixes denote different catalog ordering codes for the same drive hardware. This variant is commonly the standard ordering path for systems integrators and panel builders who specify G120X drives via the F-suffix catalog channel and commission through PROFINET or TIA Portal.

The combination of C2 EMC compliance at the drive level and 3C3 harsh-environment coating makes this variant a direct fit for water treatment plants, cooling tower fan control, and process pumping stations where both conducted emissions and corrosive atmospheres are design constraints. Without a permanently mounted panel, the drive relies on network-based commissioning and diagnostics — reducing hardware cost and leaving the cabinet door clean. The FSE frame (275 × 551 × 239 mm) keeps the 55 kW power class compact, maximizing usable cabinet volume for the application-specific hardware around it.
