USAFED-05FS1S is original Yaskawa USAFED series three-phase AC permanent magnet servo motor, specially matched with CACR-SR series VS800 CNC servo drives including CACR-SR05, CACR-SRCA05 customized OEM servo amplifiers, widely equipped on small CNC lathe, milling machine feed axes and dedicated automation precision equipment. Rated power is 0.45kW under 200V input grade, factory equipped with UTMAH-B15BSB incremental rotary encoder as standard feedback component; this motor belongs to discontinued classic old-generation F-type servo unit for traditional numerical control machinery configuration.

Rated input voltage: Three-phase AC200V, compatible with 50Hz/60Hz industrial power grid; rated working current is 3.8A under continuous full-load operation. Rated rotational speed is fixed at 1500rpm for nominal working condition; continuous rated torque matches 0.45kW power rating with short-time peak overload torque up to 300% continuous torque within allowed acceleration duration. Matched incremental encoder resolution is 6000 pulses per mechanical revolution, differential line-driver signal output for CN2 encoder port connection on paired CACR servo driver.

F-class insulated stator winding structure, totally enclosed IP50 protection grade casing design for indoor workshop environment. Standard straight solid output shaft without keyway or brake component; natural self-cooling via casing heat dissipation without auxiliary cooling fan installation. Overall motor weight is approximately 4.2kg with standard flange mounting dimension for CNC machine feed-axis mechanical assembly.

Only compatible with Yaskawa CACR-SR05XX, CACR-SRCA05XX VS800 series servo packs including various Y-suffix customized locked firmware versions such as Y119/Y124/Y-series OEM models; non-matched servo driver cannot realize normal closed-loop positioning control due to fixed encoder parameter setting pre-locked inside OEM drive firmware. Supports dual control command modes via paired driver: ±10VDC analog speed instruction or differential pulse position command for CNC host positioning signal input.

Permitted operating ambient temperature range from 0°C to +40°C; spare storage temperature spans -20°C to +70°C. Applicable relative humidity between 5% and 80%RH without internal moisture condensation inside motor casing. Reduce actual continuous load output when installation altitude exceeds 1000 meters above sea level to avoid overheat during long-time continuous operation. Allowable working vibration parameter: 10Hz~55Hz frequency band with amplitude limited below 0.5mm, forbidden installation under strong shock and corrosive gas environment.

All overcurrent, overheat, overload protection logic is realized via paired CACR servo driver side detection; motor internal embedded thermal protection sensor feeds temperature signal back to driver for overheat shutdown trigger. Common abnormal faults include encoder wire breakage leading to drive code 6 alarm, winding insulation damage causing driver overcurrent alarm code 1, mechanical blocking triggering continuous overload code 7 alert on servo drive display panel.

Direct interchange replacement only allows identical USAFED-05FS1S original unit; other suffix variant models like USAFED-05FA1S, USAFED-05FB1S differ in encoder parameter and shaft specification which cannot directly substitute without readjusting drive OEM firmware setting. Before disassembly for bearing or winding maintenance, cut off matched servo drive AC power and wait over 15 minutes for bus capacitor full discharge to prevent accidental electric shock hazard. Periodic maintenance items include encoder cable tightness inspection every three months and bearing grease replenishment every 8000 working hours; prohibit arbitrary modification of internal encoder wiring layout otherwise cause positioning runaway or drive permanent alarm lock.

Mainly applied for X/Y feed axis driving of small-size CNC lathe, bench-top machining center, automatic feeding equipment and special customized numerical control automation machinery, supporting medium-speed precision positioning and frequent start-stop cyclic working condition of machine tool mechanical structure.
