Rated power and duty cycle for pump and fan loads
The 6SL3220-3YH64-1CF0 is rated for 500 kW at 690 V, with an overload capability of 135% for 3 seconds or 110% for 60 seconds, and 100% for 240 seconds — this matches the cyclic loading profile of centrifugal pumps and axial fans in HVAC or water/wastewater duty, where peak torque occurs only during start or transient events. The drive is part of the SINAMICS G120X family, purpose-built for infrastructure converters in HVAC, water, and wastewater applications, with a built-in RFI suppression filter for category C3.
Fieldbus and IO for system integration
Integrated PROFINET PN and Ethernet IP fieldbus interfaces allow direct connection to a plant-wide automation network without an external gateway — the drive appears as a standard PROFINET IO device on the controller scan list. An IO expansion module is included, providing additional digital and analog I/O for local feedback signals such as pressure transducer inputs or valve position feedback, reducing the need for a separate remote I/O rack.
Ambient temperature and enclosure derating
Rated for an ambient temperature range of 0 to +45 °C at full output current — above 45 °C the drive must be derated per the SINAMICS G120X operating instructions, typically 2% per °C up to the maximum allowed ambient of 60 °C. The FSJ frame size requires a minimum enclosure depth of 800 mm for clearance.
Compliance and lifecycle status
RoHS compliance is confirmed since March 2020, and the REACH Article 33 duty-to-inform applies due to lead content (CAS 7439-92-1) above 0.1% w/w in certain components — the declaration is available with the shipment documentation.
