Sizing this drive for a 1.5 kW axis
The 6SL5310-1BE11-5DF0 is a SINAMICS S210 servo drive rated for a 1.5 kW motor, drawing 6.0 A from a 200-480 V three-phase supply and delivering 5.0 A to the motor at 0-550 Hz. That 550 Hz ceiling matters if you're spinning a direct-drive spindle or a high-speed servo — most general-purpose drives top out at 400 Hz. Input voltage tolerance of -10%/+10% means it stays in regulation down to 180 V and up to 528 V, so it can ride through brownouts on weak plant power without dropping the DC bus.
Panel fit and mounting
Frame size B measures 70 x 322 x 223 mm (WxHxD) with IP20 protection — it's designed for a clean, dry cabinet, not a washdown zone. The height is the dimension to watch on a shallow enclosure; 322 mm needs at least 350 mm of internal clearance for cable bend radius above and below.
