CACR refers to classic Yaskawa Yasnac VS800 full digital AC Servopack series designed for CNC feed axes and industrial automation positioning equipment.SR stands for three-mode servo drive supporting position, speed and torque control selectable via internal parameter setting.10 means the drive is matched for 1.0kW servo motor with rated continuous output current of 13.0A RMS.BB represents standard universal mainboard PCB layout and regular rack housing without special non-standard hardware alteration.1 is standard base firmware version for 200V input voltage class.A specifies only ±10VDC analog speed/torque command input with no differential pulse positioning input circuit equipped.F denotes factory fixed parameter setup; core control parameters are preconfigured and write-protected.-Y8 is exclusive OEM customized suffix with dedicated preset firmware, fixed CN1 I/O logic and machine-specific parameter grouping tailored for designated original equipment; locked parameters cannot be fully reset to universal factory default settings.

Main power supply is three-phase AC200V~230V with allowable voltage fluctuation from -15% to +10%, compatible with 50Hz and 60Hz industrial power grid.Independent single-phase AC200V~230V supplies separated power for control circuit.Continuous rated output current is 13.0A; 150% overload can continuously run for 60 seconds and 300% peak overload is restricted within maximum 3 seconds.DC bus operating voltage ranges DC280V~320V, and P/N spare terminals are reserved for external regenerative braking resistor wiring for frequent heavy-load deceleration applications.The servo uses IGBT sine-wave PWM modulation with dual closed-loop control of current loop and speed loop.

Operating ambient temperature ranges from 0℃ to +55℃; storage temperature is -20℃ ~ +70℃.Working relative humidity keeps 5%~80%RH without condensation; protection grade IP20 and vertical cabinet rack installation is mandatory.Max applicable installation altitude is below 1000 meters above sea level, and the unit withstands 10~55Hz vibration with 0.5mm single amplitude.Approximate net weight is 2.4kg.

Speed adjustment ratio reaches 1:5000 with full-load steady speed accuracy within ±0.01%.CN2 feedback port is designed exclusively for incremental encoder connection matching corresponding 1.0kW Yaskawa servo motors.Built-in digital notch filter suppresses mechanical resonance and operational vibration effectively.Auto motor parameter identification is available for basic motor setup, while gain, acceleration and deceleration parameters defined under Y8 custom program are factory locked and prohibited from arbitrary modification.Three control modes can be switched by adjusting non-locked available parameters.

R/S/T terminals connect three-phase main AC power input; U/V/W terminals link servo motor three-phase power cables; P/N terminals are used for external regenerative brake resistor connection.CN1 is opto-isolated 8-input and 6-relay-output I/O terminal block with fixed Y8 OEM customized signal definition, covering servo enable, forward/reverse overtravel limit, emergency stop, servo ready output and fault alarm output functions.CN2 is dedicated connector for incremental encoder feedback wiring.Onboard RS422 serial port adopts Yaskawa proprietary communication protocol for parameter read/write and real-time running status monitoring.

Position, speed and torque three control modes can be freely switched, and electronic gear ratio value is preset and fixed under Y8 OEM configuration.Internal dynamic braking circuit absorbs most regenerative energy during regular deceleration; external brake resistor is only required for heavy-duty frequent emergency stop conditions.Separate high/low speed gain ensures stable low-speed running and fast high-speed dynamic response.Full protection functions include overcurrent, overvoltage, undervoltage, overheat, encoder fault and motor overload protection; the drive automatically stores latest 10 historical fault codes for maintenance check.

This Y8 customized locked-parameter servo drive is exclusively matched with 1.0kW incremental servo motors for specific OEM CNC machine and dedicated automation equipment. Replacement must use identical full part number CACR-SR10BB1AF-Y8, standard CACR-SR10BB1AF without Y8 suffix cannot substitute directly.

Check all power, motor and encoder wiring for loose connection or short circuit before power-on, random modification of Y8 locked factory parameters is not allowed without equipment mechanical upgrade.Maintain good cabinet ventilation during operation, cease long continuous operation if cabinet inner temperature exceeds 55℃ and avoid frequent short-interval power cycling.Carry out routine maintenance every 3~6 months: clean heatsink dust and retighten terminal screws. Cut off main AC supply and wait over 15 minutes for full DC bus capacitor discharge before opening cover for internal maintenance to avoid electric shock risk.

Overheat alarm is commonly caused by clogged heat sink, excessive cabinet ambient temperature or long-term overload running.Encoder fault usually originates from loose CN2 connector or damaged feedback cable.Overvoltage alarm occurs under frequent rapid heavy-load deceleration; install external regenerative resistor on P/N terminals to resolve the issue.
