630 kW at 135% overload — what the rating means for the pump or fan load
The 6SL3220-2YH68-1CP0: The 630 kW rated power with 135 % overload for 3 s (or 110 % for 60 s, 100 % for 240 s) is the duty-cycle envelope that governs the drive's real-world sizing. For a centrifugal pump or fan — the target load for the SINAMICS G120X infrastructure series — the 135 % short-term overload handles the breakaway torque at start without oversizing the drive for the running condition. The 3AC 500-690 V +10/-20 % input range at 47-63 Hz covers the common medium-voltage distribution levels in European and North American HVAC plants. The integrated RFI suppression filter for category C3 means the drive meets the conducted emission limits for industrial environments (second environment) per EN 61800-3 — no external filter needed for most installations.
PROFIBUS DP integration and commissioning
Fieldbus is integrated PROFIBUS DP — no separate communication module required. The drive ships with a Basic Operator Panel (BOP) and IO expansion, so parameterisation and local control are possible before the fieldbus master is online. The BOP lets the commissioning engineer set the motor nameplate data, ramp times, and PID setpoints for the HVAC loop without a laptop. Size FSJ is the largest frame in the G120X range; the 1,200 x 1,857 x 800 mm packaging dimensions give a sense of the physical footprint for panel layout and gland-plate planning.
Lifecycle and sourcing — mature production, made to order
RoHS compliance is confirmed since 11-03-20. REACH Article 33 disclosure notes lead (CAS-No. 7439-92-1) above 0.1 % w/w — this is a standard declaration for drives with lead-bearing solder joints or component terminations, not a restriction on sale or use within the EU.
