1.CACR stands for Yasnac VS800 full digital AC Servopack series exclusively used for CNC feed axis control by Yaskawa Electric.SR supports three switchable control modes including analog speed control, torque control and parameter-enabled position control.10 means rated matching servo motor power is 1.0kW with rated continuous output current 7.6A RMS.BB denotes standard main circuit PCB and original standard metal casing without factory hardware customization.1 refers to 200V-class main power input base firmware specification.A means the drive receives ±10VDC analog speed/torque command only, without onboard built-in pulse command receiving circuit.BF suffix represents factory parameter locked OEM standard version; core gain parameters, I/O allocation, electronic gear and acceleration/deceleration parameters are pre-programmed and write-protected, cannot reset to full universal factory default freely, different from AM general open parameter model.

Main power input is three-phase AC200V~230V, allowable voltage fluctuation from minus 15% to plus 10%, applicable for both 50Hz and 60Hz industrial power grid.Control auxiliary power uses independent single-phase AC200V~230V separate input to avoid interference from main circuit fluctuation.Rated three-phase AC output ranges from zero to 230V, continuous rated output 7.6A corresponding to 1kW rated motor load.Overload capacity specification: continuous 150% rated load operation for maximum 60 seconds; instantaneous peak overload up to 300% limited within 3 seconds for motor startup acceleration requirement.DC bus nominal voltage sits between DC280V and DC320V; P terminal and BN terminal are reserved for external regenerative braking resistor wiring for equipment with frequent rapid deceleration and heavy cutting load.Control topology adopts full-wave rectification plus IGBT sine wave PWM modulation, maximum output frequency reaches 300Hz for high-speed motor operation.

Allowable continuous working ambient temperature ranges from 0 degree Celsius to positive 55 degree Celsius; product storage temperature spans minus 20 degree Celsius to positive 70 degree Celsius.Permitted working relative humidity is 5% to 80% without internal condensation; cabinet installation protection grade is IP20 after standard vertical panel mounting.Max valid installation altitude below 1000 meters above sea level without output power derating; natural convection air cooling design with no built-in cooling fan, net weight around 2.4kg.

Speed adjustment range ratio reaches 1 to 5000, full-load steady speed fluctuation controlled within ±0.01% of set value.CN2 feedback connector is designed for incremental encoder connection of matched Yaskawa 1kW servo motor, compatible with standard 6000PPR incremental encoder signal input.Built-in digital notch filter function to suppress mechanical resonance and low-speed crawling vibration during axis feeding movement.Basic motor static parameter auto-tuning function is available, but BF locked-version restricts modification on core servo parameters including speed loop gain, position loop gain, electronic gear ratio and acceleration/deceleration time constant; only minor auxiliary setting items can be adjusted by user without factory authorization.Three control modes can be switched via non-locked auxiliary internal parameters as actual machine requirement changes.

R, S, T terminals connect three-phase main AC input power supply; U, V, W terminals connect three-phase power cable of matched servo motor; P and BN terminals serve for external brake resistor connection.CN1 is opto-coupled digital I/O port with fixed pre-defined signal layout under BF factory firmware lock, including servo enable input, positive/negative travel limit input, emergency stop input, servo ready contact output and fault alarm output; user cannot rearrange CN1 I/O function assignment through parameter modification.CN2 dedicated for encoder feedback wire connection; onboard RS422 serial communication port runs Yaskawa exclusive private protocol for online parameter reading, operation data monitoring and fault record query only.

Complete multi-layer protection covers overcurrent, DC bus overvoltage, input undervoltage, drive internal overheat, encoder signal loss, motor continuous overload and internal power circuit short-circuit protection.Drive memory can store latest ten historical fault codes for maintenance troubleshooting check after failure occurs.Internal integrated dynamic brake circuit absorbs normal deceleration regenerative energy; external regenerative resistor installation is required only under frequent emergency stop and long-term heavy load cutting application.All core motion parameter sets are solidified inside BF customized firmware, mass parameter reset to universal factory default function is disabled by software lock.

Mount the servo unit vertically inside electrical cabinet with enough surrounding ventilation gap to ensure heat dissipation; reserve more than 30mm empty space above and below drive body for air circulation.Complete all power wiring and encoder wiring under power-off state; strictly separate power high-voltage cable and low-voltage feedback cable to reduce signal interference.Check wiring correctness and insulation integrity before switching main power on; apply control auxiliary power first then main three-phase power following specified power-on sequence.First execute motor static auto-tuning after initial power-on, avoid high-speed trial run before finishing tuning procedure.

Regularly check fastening condition of power terminals, motor wiring terminals and CN2 encoder plug every three months; do not attempt to unlock protected core BF parameters without original machine maker permission.Suspend continuous operation once cabinet inner ambient temperature exceeds 55 degree Celsius to avoid overheat protection alarm trigger.Cut off all AC input power and wait minimum 15 minutes for internal DC bus capacitor full discharge before opening drive outer cover to prevent electric shock hazard.Clean radiator accumulated dust every three to six months to keep normal heat dissipation performance.

Overheat alarm triggers mainly caused by blocked radiator dust accumulation, excessive cabinet environment temperature or long-term continuous overloaded operation.Encoder fault alarm usually comes from loose CN2 connector plug or damaged encoder feedback cable line.DC overvoltage alarm during frequent fast deceleration needs external regenerative resistor mounted between P and BN terminals for surplus energy consumption.Parameter writing failure happens when user tries to revise BF locked core parameters due to factory firmware write protection setting.

1 stands for main circuit overcurrent fault; 2 means drive body overheat protection; 3 represents DC bus overvoltage alarm; 4 is input power undervoltage fault; 5 indicates encoder feedback signal abnormal; 6 refers to motor continuous overload protection triggered.

CACR-SR10BB1BF cannot be directly replaced by general CACR-SR10BB1AM model without parameter redo and CN1 I/O redefinition due to BF fixed locked parameters and fixed I/O definition; replacement needs same full part number for direct plug and run on original CNC machine equipment. Mainly matched for fixed OEM brand CNC lathe and vertical machining center feed axis driving application.
