Siemens 6SN2155-2BF21-1BA1 SIMODRIVE POSMO A programmable positioning motor, described as a brushless motor and PROFIBUS DP standard slave. Alternate catalogue reference: 6SN21552BF211BA1.Recorded unit markings P/N: A5E00297165 S/N: 02P8000268 Un = 48V DC; S3 25% 4min; IP65 Nn = 3500/min; S3:3000/min In = 5,25A; S3:10,5A Pn = 176W; S3:300W Tmax = 45°C Configuration and speed require confirmationThe opening description says without gearbox, smooth shaft, without brake. A later source line instead says PLANETARY GEARS 1=7 WITH BRAKE IP65. These conflicting configurations are retained without choosing one; the 1=7 notation has not been corrected or decoded into a confirmed ratio.The original 350RPM tag also differs from the recorded 3500/min and S3:3000/min markings. Confirm whether a gearbox is fitted, the brake configuration and motor/output-shaft speeds from the actual unit labels. The 300W and 10,5A values are S3-duty entries, not continuous ratings; the separate 176W and 5,25A markings are retained.Confirm the complete assembly, control compatibility and supplied accessories before ordering. IP65 is recorded from the source, not an independent test of the unit's current sealing condition.
