1. Model Code Definition
CACR belongs to Yaskawa classic Yasnac VS800 full digital AC Servopack series developed for CNC machine feed axis driving.SR means three optional control modes including position, speed and torque control which can be switched via internal parameter setting.10 stands for rated matching motor power of 1.0kW with continuous rated output current of 7.6A RMS.BB indicates standard original mainboard PCB design and regular standard housing without hardware structure alteration.1 represents base firmware edition designed for 200V AC power supply class.B specifies only ±10VDC analog speed/torque command input, lacking built-in differential pulse position command receiving circuit.F is factory locked parameter specification, core control parameters are preset and write-protected from factory, full reset to universal factory default is unavailable.-H is special customized OEM suffix, with upgraded internal dynamic braking circuit and exclusive fixed I/O definition optimized for heavy-duty frequent start-stop working condition, different from standard CACR-SR10BB1BF.
2. Electrical Specifications
Main power supply is three-phase AC200V~230V with permissible voltage fluctuation of -15%~+10%, compatible with 50Hz and 60Hz industrial power grid.Independent single-phase AC200V~230V is arranged separately for control circuit auxiliary power input.Continuous rated output current is 7.6A; 150% overload can keep running for 60 seconds and 300% peak overload is limited within maximum 3 seconds.DC bus operating voltage ranges DC280V~320V, P/N spare terminals are reserved for external regenerative braking resistor connection under frequent heavy-load rapid deceleration.This model adopts IGBT sine-wave PWM modulation, maximum output frequency is upgraded to 400Hz for H version to adapt high-speed heavy-load operation.
3. Environmental and Mechanical Parameters
Operating ambient temperature ranges from 0℃ to +55℃; storage temperature is between -20℃ and +70℃.Working relative humidity keeps 5%~80%RH without condensation, protection grade IP20 and vertical cabinet rack installation is required.Maximum applicable installation altitude is below 1000 meters above sea level, the drive can resist vibration of 10~55Hz with 0.5mm single amplitude.Approximate net weight is 2.4kg.
4. Control Performance
Speed adjustment ratio reaches 1:5000 with full-load steady speed accuracy controlled within ±0.01%.CN2 feedback port matches incremental encoder of corresponding 1.0kW Yaskawa servo motor, compatible with high-resolution encoder for heavy-load machining.Built-in digital notch filter effectively suppresses mechanical resonance and low-speed vibration under frequent start-stop operation.Basic motor parameter auto-tuning function is retained, while core gain, acceleration and deceleration parameters are pre-locked by H customized firmware and cannot be modified arbitrarily.Three control modes can be switched through available unlocked auxiliary parameters.
5. Interface Configuration
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 wiring.CN1 is opto-isolated 8-input and 6-relay-output I/O terminal block with exclusive fixed signal assignment defined for H version OEM equipment, including servo enable, forward/reverse overtravel limit, emergency stop, servo ready output and fault alarm output; users cannot redefine I/O allocation by parameters.CN2 is dedicated connector for incremental encoder feedback wiring.Onboard RS422 serial port adopts Yaskawa proprietary communication protocol for parameter reading, writing and real-time running status monitoring.
6. Core Functions and Protection
Three control modes can be switched freely, internal dynamic braking capacity is enhanced on H version to cope with frequent deceleration energy dissipation, external brake resistor is only needed under ultra-heavy-duty continuous emergency stop condition.Separated high and low speed gain settings guarantee stable low-speed feeding and rapid dynamic response under heavy cutting load.Complete protection covers overcurrent, overvoltage, undervoltage, overheat, encoder fault and motor overload protection; the drive automatically saves latest ten groups of historical fault codes for maintenance check.
7. Application & Replacement Note
This BF-H customized heavy-duty servo is exclusively matched with 1.0kW incremental servo motors for specific OEM heavy-cutting CNC lathes and machining centers; replacement must use identical full part number CACR-SR10BB1BF-H, standard CACR-SR10BB1BF cannot directly substitute due to upgraded braking performance and fixed H-type I/O & parameter setting.
8. Maintenance Instructions
Check tightness of all power, motor and encoder wiring to avoid loose connection or short-circuit before power-on; random modification of locked factory parameters is forbidden without original equipment manufacturer’s approval.Ensure cabinet ventilation unobstructed during operation and stop long-time continuous running once inner cabinet temperature exceeds 55℃.Carry out routine maintenance every 3~6 months including cleaning heatsink dust and retightening terminal screws. Cut off main AC power and wait over 15 minutes for full DC bus capacitor discharge before opening cover for overhaul to prevent electric shock risk.
9. Basic Troubleshooting
Overheat alarm is usually caused by blocked heatsink, high cabinet ambient temperature or long-term heavy overload running.Encoder fault alarm mostly originates from loose CN2 connector or damaged feedback cable.Overvoltage alarm occurs under frequent heavy-load rapid deceleration; install external regenerative resistor on P/N terminals to eliminate excess bus voltage.Parameter writing failure appears when attempting to alter H-version locked core parameters due to factory write protection.
