CACR refers to classic Yaskawa Yasnac VS800 full digital AC Servopack series used for CNC feed axis and automated positioning machinery.SR represents three-control-mode servo unit; position, speed and torque control can be switched via internal parameter setting.09 is rated for 0.9kW servo motor with continuous rated output current of 11.7A RMS.T stands for custom rack-mounted mechanical structure with special housing design different from standard B series outline.Z means customized modified mainboard PCB and exclusive internal OEM circuit layout.6 indicates 6th revised customized firmware edition based on 200V voltage class platform.S supports dual control input: differential pulse signal for position plus ±10VDC analog signal for speed/torque instruction.F denotes factory fixed locked parameter type; core application parameters are OEM preset and cannot be fully restored to universal factory default settings.

Main power supply is three-phase AC200V~230V with allowable voltage deviation from -15% to +10%, applicable for 50Hz and 60Hz industrial power grid.Independent single-phase AC200V~230V is arranged separately for control circuit power supply.Continuous rated output current is 11.7A; 150% overload can keep running for 60 seconds and 300% peak overload is allowed for maximum 3 seconds.DC bus working voltage is DC280V~320V, P/N spare terminals are reserved for external regenerative braking resistor connection under frequent heavy-load deceleration condition.The driver adopts 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 ranges between -20℃ and +70℃.Relative humidity maintains 5%~80%RH without condensation, protection grade IP20 and only for vertical cabinet installation.Maximum 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 2.3kg.

Speed regulation ratio reaches 1:5000, full-load steady-state speed accuracy is within ±0.01%.CN2 encoder port matches incremental encoder and is hardware compatible with absolute encoder for Z customized circuit.Built-in digital notch filter suppresses mechanical resonance and operational vibration.Auto motor identification works for basic motor parameter setup, while F-version locked gain, acceleration and deceleration parameters are protected from arbitrary modification.Three control modes are adjustable via available unlocked parameters.

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

Three control modes can be switched freely; electronic gear ratio function realizes multi-axis synchronous movement for automation equipment.Internal dynamic braking circuit absorbs most regenerative energy during regular deceleration; external brake resistor is required only for heavy-load frequent emergency stop applications.Separated high and low speed gain parameters guarantee stable low-speed running and fast high-speed dynamic response.Complete protection covers overcurrent, overvoltage, undervoltage, overheat, encoder fault and motor overload; the unit automatically saves latest 10 fault codes for maintenance reference.

This OEM customized servo matches 0.9kW Yaskawa servo motor for designated CNC machine and dedicated automated production equipment, replacement requires identical full part number CACR-SR09TZ6SF.Check all power, motor and encoder wiring for loose connection or short circuit before power-on; do not modify locked factory parameters randomly.Keep cabinet well ventilated, suspend continuous operation when inner cabinet temperature exceeds 55℃ and avoid frequent short-interval power cycling.Carry out routine maintenance every 3~6 months: clean dust on heatsink and retighten terminal screws. Cut off main power and wait more than 15 minutes for full discharge of internal capacitor before disassembling to avoid electric shock.Overheat alarm is caused by blocked heatsink, high ambient temperature or long-term overload; encoder fault usually comes from loose CN2 connector or damaged feedback wire; overvoltage during frequent heavy deceleration can be solved by installing external regenerative resistor on P/N terminals.
