Siemens 6SL3220-1YD14-0CB0 - SINAMICS G120XA infrastructure converter for documented industrial drive duty

SINAMICS G120XA infrastructure converter that controls a pump or fan motor for the documented G120XA infrastructure-converter duty in the documented Siemens drive system.

Documented system function

Rebuilt from individual evidence

The cited Siemens documentation identifies 6SL3220-1YD14-0CB0 as SINAMICS G120XA infrastructure converter.

Its documented role is to controls a pump or fan motor for the documented G120XA infrastructure-converter duty; the cited source records 380-440 V three-phase input, a 1.5 kW low-overload rating, and the C3-filtered variant.

In the system, it is between the three-phase AC supply and a standard pump or fan motor.
