The 6SL3230-3YE30-1AF0 is the F-suffix variant of the 18.5 kW C2-filtered G120X with DC link terminals. Electrically identical to the P-suffix (6SL3230-3YE30-1AP0), it shares the 51.3 A power stage, integrated Category C2 EMC filter, DC terminal provision, and FSD frame (200 × 472 × 239 mm, IP20).

1AF0 in the 18.5 kW G120X landscape

The 1AF0 belongs to the 1Ax group at 18.5 kW: C2 filtered, with DC terminals, F-suffix alternative ordering code. The 18.5 kW 1Ax variants (1AP0/1AF0) are the C2-filtered counterparts to the 1Ux unfiltered variants (1UP0/1UF0/1UB0) at the same power level. Engineers choosing between them should evaluate whether the installation's EMC requirements justify the integrated C2 filter — the 1Ax group provides per-drive filtering without external components, while the 1Ux group leaves EMC compliance to the cabinet-level design.
