Description
1. Model Code Definition
CACR stands for classic Yaskawa Yasnac VS800 full digital AC Servopack series for CNC feed axes and automated positioning equipment.SR indicates multi-mode servo drive with position, speed and torque control switchable via internal parameter setting.09 means rated matched motor power is 0.9kW with rated continuous output current of 11.7A RMS.T refers to custom rack-mounted mechanical structure with modified housing layout different from standard B-type models.Z represents customized revised mainboard PCB and exclusive internal circuit design.0 denotes base firmware version for 200V power class.S stands for dual command input supporting both differential pulse signal and ±10VDC analog instruction.F means factory fixed parameter specification with locked OEM preset parameters; full factory default reset is unavailable.
2. Electrical Specifications
Main power supply is 3-phase AC200V~230V with permissible voltage fluctuation of -15%~+10%, compatible with 50Hz/60Hz grid.Independent single-phase AC200V~230V is supplied separately for control circuit power.Continuous rated output current is 11.7A; 150% overload can continuously run for 60 seconds and 300% peak overload lasts maximum 3 seconds.DC bus voltage ranges DC280V~320V; P/N spare terminals are reserved for external regenerative braking resistor for frequent heavy-load deceleration conditions.Drive adopts IGBT sine-wave PWM with dual closed-loop control of current loop and speed loop.
3. Environmental and Mechanical Parameters
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 for vertical cabinet installation only.Max installation altitude ≤1000m above sea level; anti-vibration performance: 10~55Hz, single amplitude 0.5mm.Approximate net weight is 2.3kg.
4. Control Performance
Speed adjustment ratio reaches 1:5000 with full-load steady speed accuracy within ±0.01%.CN2 feedback port is compatible with serial absolute encoder due to Z-type onboard absolute encoder circuit, also supports incremental encoder alternatively.Built-in digital notch filter suppresses mechanical resonance and running vibration.Auto motor parameter identification is available for basic tuning while core OEM parameters of F version are factory locked and protected against arbitrary modification.Three control modes can be switched by adjusting unlocked available parameters.
5. Interface Configuration
R/S/T: three-phase main AC power input terminals; U/V/W: servo motor three-phase power output terminals; P/N: terminals for external regenerative brake resistor connection.CN1 is opto-isolated 8-input and 6-relay-output I/O block with fixed factory-defined signal logic, including servo enable, forward/reverse overtravel limit, emergency stop, servo ready output and fault alarm output.CN2 is dedicated connector for incremental or serial absolute encoder feedback wiring.Onboard RS422 serial port with proprietary Yaskawa protocol supports parameter read/write and real-time operation status monitoring.
6. Core Functions & Protection
Three control modes can be switched freely; electronic gear ratio function enables multi-axis synchronous motion for automation equipment.Internal dynamic braking circuit absorbs regular regenerative energy during deceleration; external brake resistor is required only for frequent heavy-duty emergency stop.Separated high/low speed gain ensures smooth low-speed running and rapid high-speed dynamic response.Complete protection includes overcurrent, overvoltage, undervoltage, overheat, encoder disconnection and motor overload protection. The drive automatically stores latest 10 fault codes for maintenance reference.
7. Application & Replacement Note
This fixed-parameter customized servo is specially matched with 0.9kW Yaskawa incremental or absolute servo motors for designated OEM CNC and automation production equipment. Replacement must use identical part number CACR-SR09TZ0SF directly.
8. Maintenance & Troubleshooting
Check all power, motor and encoder wiring for loose connection or short circuit before power-on. Avoid unauthorized change of locked factory parameters. Ensure good cabinet ventilation; stop long-running if inner temperature exceeds 55℃ and avoid frequent power cycling within short intervals.Periodic maintenance every 3~6 months: clean heatsink dust and retighten terminal screws. Cut off main power and wait over 15 minutes for full DC capacitor discharge before cabinet disassembly to prevent electric shock.Overheat alarm mainly results from blocked heatsink, high ambient temperature or continuous overload; encoder fault is commonly caused by loose CN2 plug or damaged feedback cable; overvoltage during frequent heavy deceleration can be solved by installing external regenerative resistor on P/N terminals.
