315 kW at 500–690 V – overload profile for pump and fan loads
The 6SL3220-2YH56-1CB0: Rated power is 315 kW with an overload capability of 135 % for 3 s or 110 % for 60 s, 100 % for 240 s – the 110 %/60 s window covers the starting inrush of a centrifugal pump against a closed discharge valve without tripping on overcurrent. Input supply is 3AC 500–690 V +10/-20 %, 47–63 Hz, so it lands on a 575 V or 600 V plant distribution without a step-down transformer – confirm the line-side voltage matches the drive's nominal range before committing the BOM.
Fieldbus integration – MODBUS RTU and BACnet MS/TP on board
The drive ships with MODBUS RTU, BACnet MS/TP, and USS as standard – no option card needed for a BAS (building automation system) drop. The RS-485 termination and bias resistors are set at commissioning; a stray termination on a BACnet segment pulls the bus below the recessive threshold. The Basic Operator Panel (BOP) is included for local parameter access and fault diagnosis – useful during loop checks before the network handshake is live.
Size FSH, IP20 – panel layout and cooling
Packaged dimensions are 800 x 1,870 x 600 mm (L x W x H) – the FSH frame requires a backplate that clears the gland plate at the bottom and leaves 200 mm above for cable entry bend radius. IP20 / UL open type means the drive is not sealed against dust ingress; mount it inside a ventilated enclosure with a filter fan if the ambient is above 45 °C. Ambient temperature rating is 0 to +45 °C – derate output current above 40 °C per the SINAMICS G120X manual; the 315 kW figure assumes full cooling at 45 °C.
Active production – sourcing posture for this drive
The part is manufactured to order (product class C), so lead time and volume pricing are confirmed at RFQ against the specific BOM quantity. RoHS compliance date is 11-03-20; REACH Article 33 disclosure lists lead (CAS 7439-92-1) above 0.1 % w/w – the declaration is available with the shipment documentation.
