CACR-SR05BB1AF-Y114 is a customized OEM 0.5kW analog AC SERVOPACK under Yaskawa legacy CACR-SR series, exclusively factory modified with suffix Y114 special parameter solidification, matching original YASNAC VS-800 CNC system for old Japanese lathe and machining center equipment. Different from standard CACR-SR05BB1AF without suffix, Y114 version locks original factory parameter group, core gain, electronic gear ratio and encoder matching data are preset by OEM; user cannot modify core factory parameters at will after parameter reset, only partial auxiliary parameters are editable on site. It pairs with USAREM-05 / USAGED-05 500W incremental servo motor with 1000P/R A/B/Z phase encoder feedback, BB version exclusive mainboard layout remains consistent with base BB model hardware structure.

CACR refers to classic Yaskawa analog AC servo amplifier series. SR stands for triple closed-loop control supporting speed, position and torque via ±10VDC analog command signal for VS-800 CNC controller. 05 means rated continuous output power 0.5 kilowatt. BB represents exclusive BB revision mainboard circuit design independent from BA, AY, AZ series PCB. Digit 1 indicates CN2 feedback port designed only for 1000P/R incremental rotary encoder. AF is standard motor matching specification for USAGED/USAREM-05 servo motors. Y114 is OEM custom modification code, meaning factory preloaded fixed dedicated parameter set for designated CNC machine model with parameter write lock function.

Main power supply requires three-phase AC 200V to 230V, input voltage tolerance plus 10 percent and minus 15 percent, rated input frequency 50Hz or 60Hz. Control circuit uses separate independent single-phase AC 200V~230V power source isolated from main power loop. Rated continuous output current is 4.2Arms, short-time peak overload output current reaches 11.0Arms valid within maximum 3 seconds overload duration. Internal power inverter adopts full IGBT sine-wave PWM drive topology.CN1 terminal connector receives ±10VDC analog speed or position command signal transmitted from VS-800 CNC main unit, meanwhile reserves access for external analog speed reference input and torque limit analog signal. CN2 dedicated socket connects incremental encoder A/B/Z phase pulse feedback from matched 1000PPR servo motor. External terminal block includes wiring points for external dynamic brake resistor, servo ready alarm output contact, servo enable input and fault reset digital input signal.

This servo unit applies natural air convection cooling without built-in cooling fan, protection grade IP20 and must be installed inside sealed electrical control cabinet only, forbidden open-air mounting. Normal working ambient temperature range is zero degree Celsius to fifty-five degree Celsius; permissible storage temperature spans minus twenty degree Celsius to eighty-five degree Celsius. Working environment relative humidity should not exceed eighty percent without condensation, installation location needs to avoid corrosive gas, conductive dust and liquid splashing. Max allowable installation altitude is one thousand meters above sea level from sea level. Standard DIN rail vertical mounting structure same as base BB series drive, dimension unchanged versus non-Y114 standard model.

The core difference between Y114 customized version and ordinary CACR-SR05BB1AF lies in parameter locking mechanism. After factory preset for specific OEM machine tool, core servo gain parameters, encoder count setting and mechanical matching parameters are solidified inside firmware. If user executes full parameter factory reset operation, drive automatically restores back to fixed Y114 original OEM parameters instead of universal default factory data of standard BB model. Users can only fine-tune minor auxiliary parameters like acceleration time and fault output logic, key motion control parameters remain write protected and unmodifiable. All hardware protection functions keep consistent with standard model including overcurrent, overvoltage, undervoltage, overheat, encoder loss and overload alarm protection, seven-segment front panel display outputs consistent fault code definition as common BB series drive for troubleshooting.

Mainly used as original replacement spare part for vintage Japanese CNC lathe and small machining center equipped with VS-800 control system requiring Y114 customized servo parameter configuration, unavailable to directly substitute with regular non-Y suffix standard servo due to fixed parameter mismatch after replacement.
