CACR-SR03SZ1SS-Y223
CACR-SR03SZ1SS-Y223 is a 0.3kW discontinued Yaskawa AC Servopack from the classic CACR-SR series. It is OEM customized with factory-locked Y223 parameter firmware exclusively for Yasnac VS-800 CNC systems, used as feed-axis drive on custom CNC lathes and small machining centers, and paired with Yaskawa USAF series 300W incremental encoder servo motors. Original production has been terminated, and this unit is only supplied as spare replacement for maintenance of aging dedicated machine tools. The suffix Y223 stands for unique factory preset locked parameters developed for specific machine specifications.
Description
1. Product Overview
CACR-SR03SZ1SS-Y223 is a discontinued 0.3kW Yaskawa AC Servopack of classic CACR-SR series, OEM customized with factory-locked Y223 parameter firmware exclusively for Yasnac VS-800 CNC system. It functions as feed-axis driver for custom CNC lathes and small machining centers and matches USAF series 300W incremental encoder servo motors. Original mass production is stopped; this model is only used as replacement spare part for maintenance of special old machine tools. The suffix Y223 stands for fixed factory parameters dedicated to specified machine configuration.
2. Part Number Breakdown
CACR: General designation of Yaskawa AC servo amplifier series.SR: Universal control platform supporting speed, position and torque control via internal parameter setup.03: Rated output power 0.3kW.SZ: Custom 200V-class main power board with unique internal circuitry, different from SB / BB / BY board types.1SS: S-type control PCB plus SS dedicated incremental encoder interface circuit.Y223: OEM custom code; all core servo parameters are pre-programmed and locked from factory editing.
3. Electrical Ratings
Main power: 3-phase AC200~230V (+10%/-15%), 50/60Hz; control power is separate single-phase AC200~230V.Rated continuous output current: 3.0Arms; peak short-time overload current: 8.5Arms for acceleration/deceleration.Operating temperature: 0℃~55℃; storage: -20℃~85℃; operating humidity ≤80%RH non-condensing. IP20 enclosure rating for cabinet installation only, avoid dust, oil mist and corrosive gas surroundings. Drive uses IGBT sine-wave PWM modulation and receives ±10VDC analog command from Yasnac CNC controller.
4. Control & Protection Features
Three selectable control modes: speed, position, torque. Critical parameters including loop gains and electronic gear ratio are locked by Y223 OEM firmware; unauthorized parameter changes cause irregular motor movement or positioning errors. Onboard anti-interference design ensures steady incremental encoder feedback under harsh factory EMI environment.Full protection covers overcurrent, overvoltage, undervoltage, overheat, regenerative circuit fault, encoder missing pulse and CPU malfunction. Single 7-segment LED on front displays running status and fault codes; P/N terminals are reserved for external regenerative braking resistor connection.
5. Wiring Specification
R/S/T: Three-phase AC input; U/V/W: Servo motor power output; PE: Mandatory protective earthing per local electrical codes; P/N: External brake resistor terminals.Control terminal block accepts ±10VDC analog command, digital input for servo enable and fault reset, and dry-contact relay output for external fault alert. Special circular aviation plug follows SS-Y223 exclusive pinout for incremental encoder wiring.
6. Installation & Commissioning
Install vertically inside control cabinet with upper and lower clearance reserved for heat dissipation, away from heat sources like transformers and contactors. Complete full wiring inspection before power up. Pre-locked Y223 factory parameters allow plug-and-play replacement without large-scale parameter modification. Execute no-load jog test to confirm rotation direction and stability before coupling mechanical load.
7. Maintenance Guidelines
Disconnect all power and wait minimum 10 minutes for internal capacitor high-voltage discharge before maintenance to prevent electric shock. Clean cooling slots and retighten terminals quarterly. Upon fault alarm, troubleshoot sequentially power fluctuation, mechanical motor binding, loose encoder wiring and poor ventilation. Do not repeatedly power on until faults are fully resolved; altering locked Y223 customized parameters is prohibited.
