USAFED-09CS2K belongs to classic Yaskawa USAFED F-series permanent magnet AC servo motor, exclusively designed to mate with CACR-SR series VS800 CNC servo amplifiers including customized Y-suffix locked-drive variants such as CACR-SR30SBXX, CACR-SRCA30BBXX used for CNC machine feed axis control. Rated output power is 0.85kW under 200V-class power specification, developed for medium-load frequent start-stop positioning of CNC lathes, milling machines and special automated equipment; suffix K stands for OEM-customized encoder wiring and fixed parameter matching for designated locked firmware servo drives.

Rated input power source: 3-phase AC200V~230V, 50/60Hz industrial input; continuous rated working current is 6.2A at full-load rated operation. Nominal rated rotating speed fixed at 1500rpm, continuous rated torque reaches 5.39Nm; instantaneous peak overload torque can hit 300% rated continuous torque within 3 seconds for rapid acceleration and heavy startup load.Equipped with UTMAH-B15 series differential incremental rotary encoder, 6000 pulses per revolution line-driver output signal matching CN2 feedback port of paired CACR-SR servo drive; K suffix locks encoder communication parameter at factory, incompatible with non-custom standard servo driver without firmware modification.Brake part uses DC90V electromagnetic holding brake, requiring independent external DC power supply for brake release during motor running; brake engages automatically once power cuts off to lock mechanical shaft position against free sliding.

Totally enclosed construction with IP50 protection grade, F-class stator winding insulation standard; C-type brake version adds compact brake housing at motor rear end, overall net weight approx 5.1kg. Straight keyed output shaft with standard flange mounting dimension for direct connection with reducer or ball screw of machine feed axes; natural air cooling via motor casing heat dissipation without auxiliary cooling fan design.

Only compatible with Yaskawa CACR-SR30SB, CACR-SRCA30BB series VS800 servo packs including Y119/Y124 customized locked firmware drives mentioned previously; standard non-Y suffix general CACR drivers cannot achieve normal closed-loop operation due to K-fixed encoder and brake control parameter lock inside drive program. Supports dual command control via matched driver: ±10V analog speed command or differential pulse position command from CNC controller.

Allowable working ambient temperature range: 0℃ ~ +40℃; storage temperature: -20℃ ~ +70℃. Operating ambient relative humidity 5%~80%RH with no internal condensation inside motor casing. When installation altitude exceeds 1000m above sea level, derate continuous load output to avoid long-running overheat damage. Permissible working vibration 10Hz~55Hz with amplitude less than 0.5mm; forbidden installation under corrosive gas, dust-saturated or continuous splashing liquid workshop environment.

Motor winding overheat detection signal is fed back to matched CACR servo drive for overload protection trigger; brake coil short/open circuit, encoder cable disconnection will trigger corresponding drive fault codes: Code 6 for encoder wire breakage, Code7 for long-time motor overload, Code1 for winding short-circuit overcurrent alarm on servo panel display. Brake failure will cause axis dropping during power-off shutdown and mechanical collision of machine tool.

Direct interchange replacement only permits original same part USAFED-09CS2K; variants such as USAFED-09CS2S, USAFED-09FS2K differ in brake configuration or encoder parameter which cannot direct substitute unless driver customized firmware is rewritten by original equipment manufacturer.Before disassembling motor for bearing maintenance or brake overhaul, fully cut off both motor main AC power and brake DC power supply, wait more than 15 minutes for servo internal DC bus capacitor full discharge to prevent electric shock hazard. Periodic maintenance: inspect encoder cable and brake wiring tightness every 3 months, replenish bearing lubricating grease every 8000 running hours; arbitrary modification on encoder internal wiring or brake circuit will result in motor runaway or permanent servo fault locking.

Mainly deployed on X/Y/Z feed axes of medium-sized CNC lathe, small vertical machining center, automatic feeding machinery and customized special numerical control equipment, suitable for cyclic frequent start-stop, precision positioning medium-load working condition.
