What This Drive Is and What It Needs
The 6SL3211-0KB13-7UA1: This is a spare-part variant: it ships without a BOP (Basic Operator Panel) and without an RS-485 interface. The drive uses a flat heat sink and is designed exclusively for cooling plate installation — it needs a metal panel or backplate to sink heat, not free-air convection. The IP20 enclosure keeps it inside a cabinet.
Ratings That Matter for the Line
The 0.37 kW rating at 200-240 V single-phase covers small pumps, fans, and conveyors. The constant-torque (CT) and variable-torque (VT) ratings are the same here — 0.37 kW — so there is no headroom to oversize for a heavier load. The CT overload capability is 150% for 60 seconds, which handles short-duration starting torque on a centrifugal load or a light conveyor. Input frequency range is 47-63 Hz, so it works on 50 Hz and 60 Hz mains without derating. The ambient temperature range of -10 to +50 °C is typical for a cabinet-mounted drive; keep it above freezing and below the high end for reliable electrolytic capacitor life.
Mounting and Integration
The drive measures 150 x 90 x 101 mm (HxWxD) and mounts via the flat heat sink to a cooling plate — this is not a DIN-rail clip-on. The cooling plate must be clean, flat metal for thermal transfer; thermal paste or a pad is typical. The unfiltered variant means you supply the line-side EMC filter externally if the application requires conducted emissions compliance. Analog input is standard; no onboard fieldbus or RS-485 port, so control is via the analog setpoint and digital inputs. For a simple fixed-speed pump or fan replacement, this keeps the wiring straightforward.
Sourcing and Lifecycle Reality
The mature lifecycle stage means this drive is still available through supply channels but is not the current series — SINAMICS G120 or G120C are the active-generation alternatives for new designs. For a BOM line that already specifies the 6SL3211-0KB13-7UA1, it is sourced and quoted to order against an RFQ through independent distribution.
