Sizing the drive to a 0.1 kW axis
The Siemens 6SL5310-1BB10-1CF0 is a single-phase SINAMICS S210 servo converter taking a 200-240 V 1AC input at 1.4 A and delivering a 0-550 Hz, 0.8 A output stage sized for a 0.1 kW motor, all in a frame-size A housing at 45 x 170 x 170 mm (W x H x D). That footprint and the IP20 protection class put it inside the cabinet on a standard mounting plate rather than out on the machine frame — the cooling envelope is the frame-size A heat sink, and the 45 mm panel width means several converters stack cleanly side-by-side in a multi-axis panel without crowding the wiring gutter.
What the rating envelope means at commissioning
The 1.4 A line-side draw and 0.8 A motor-side output are matched to small synchronous servomotors in the 0.1 kW class — positioning tables, lab automation axes, and small-format feeders where the converter sits within a few metres of the motor to keep the cable capacitance low. The output frequency ceiling of 0-550 Hz is what allows high-speed spindle or rotary indexing moves without pushing the drive into field-weakening; 45-66 Hz on the input side means the same unit runs on either 50 Hz or 60 Hz plant mains without re-configuration.
Lifecycle and supply posture
The product class C designation means each unit is built to order and cannot be returned against credit, so the BOM quantity should match the real axis count rather than a buffer buy; the price and lead time are confirmed at RFQ.
Compliance paperwork the inspector will ask for
Export classification is AL:N / ECCN:3A999A, so cross-border shipments route through the standard export-control review rather than a special-licence queue.
