55 kW heavy-duty rating with 150% overload ceiling
The SINAMICS G120C 6SL3210-1KE31-1UF1 is rated for 55.0 kW continuous output with 150% overload for 3 seconds — that overload ceiling handles the breakaway torque of a loaded conveyor or crusher without tripping on the I²t limit. The PROFINET-PN fieldbus interface connects directly to an S7-1500 or S7-1200 controller with cycle times down to 1 ms, suiting isochronous real-time motion sequences.
I/O count and control supply constraints
The onboard I/O — 6 digital inputs, 2 digital outputs, 1 analog input, 1 analog output — covers basic start/stop, speed presets, and fault reset without an expansion module. The single analog input limits closed-loop PID to one process variable; applications needing dual-loop control (e.g., pressure and flow) require the optional I/O expansion module. The drive requires an external 24 VDC control supply (typically 1-2 A) — the main 3-phase input only powers the DC bus and motor stage, so a separate power supply must be budgeted in the panel bill of materials.
Lifecycle and compliance — mature but active
RoHS compliant since 2017-02-13. REACH Article 33 notification applies for lead (CAS 7439-92-1) above 0.1% w/w — the lead is in solder joints and power semiconductor die attach; this is a pass-through disclosure obligation, not a restriction on sale or installation. Export control classification AL: N / ECCN: 9N9999 means no special export license is required for most destinations.
