The Siemens 6SL3220-2YH68-0CF0 is a SINAMICS G120X infrastructure converter rated 630 kW, designed for HVAC, water, and wastewater applications where variable-torque loads dominate. This is not a general-purpose industrial drive — the G120X family is purpose-built for pump, fan, and compressor duty cycles, where the 135% overload for 3 seconds and 110% for 60 seconds (100% for 240s) matches the starting and stall conditions of centrifugal loads without oversizing the drive. The 3AC 500-690 V +10/-20% input range covers 50/60 Hz supplies across global infrastructure sites, from 500 V mining grids to 690 V marine or European industrial networks. The integrated EMC filter meets Category C3, meaning it is suitable for industrial environments with a dedicated transformer — not for residential or public low-voltage networks without additional filtering.
Frame FSJ, IP20, and fieldbus — panel integration constraints
Frame size FSJ is the largest in the G120X family, requiring a floor-standing or large-cabinet enclosure. Integrated fieldbus is PROFINET-PN and EtherNet/IP, both on the same physical port, so the drive can commission into either Siemens S7 or Rockwell ControlLogix environments without a gateway. The Basic Operator Panel (BOP) is included for local parameter access and fault diagnosis; no IO expansion module is fitted as standard, so any digital/analog I/O needed beyond the drive's base terminals must be added via the optional IO expansion slot.
Overload duty and ambient temperature — derating reality
The overload capability is specified as 135% for 3 seconds or 110% for 60 seconds, with a continuous 100% for 240 seconds — this is a high-overload profile suitable for starting high-inertia fans or for riding through pump start transients. The ambient temperature range is 0 to +45 °C; above 45 °C the drive must be derated per the SINAMICS G120X operating instructions, which typically reduces output current by 1.5% per degree up to 60 °C maximum.
Active production, made to order — sourcing posture
RoHS compliance is confirmed since 11-03-20. The REACH Article 33 disclosure notes lead content (CAS 7439-92-1) above 0.1% w/w — this is typical for solder joints in power electronics and does not affect qualification for industrial use, but should be noted for end-of-life recycling declarations. Export control classification is AL N / ECCN 3A999A, meaning no special license is required for most commercial destinations.
