CACR-SR03SZ1SS-Y230 is a discontinued 0.3kW Yaskawa AC Servopack from classic CACR-SR series, OEM customized with factory-locked Y230 parameter firmware exclusively for Yasnac VS-800 CNC system. It is used for feed-axis drive on customized CNC lathes and small machining centers and matched with Yaskawa USAF series 300W incremental encoder servo motors. Original mass production has been discontinued, and this servo unit is only used as replacement spare part for maintenance of aged dedicated machine tools. The suffix Y230 represents exclusive pre-set locked parameters customized for specific machine configuration.

CACR is general series designation of Yaskawa AC servo amplifier. SR stands for universal control platform supporting speed, position and torque control via internal parameter configuration. 03 means rated output power of 0.3kW. SZ refers to dedicated 200V-class main power board with unique internal circuit design different from SB, BB and BY specifications. 1SS indicates S-type control PCB integrated with SS-spec incremental encoder interface circuit. Y230 is OEM custom marking, all core control parameters are pre-programmed and locked at factory.

Main power supply is three-phase AC 200V~230V with +10%/-15% tolerance at 50Hz or 60Hz; independent single-phase AC 200~230V supplies power for control circuit. Rated continuous output current is 3.0Arms and peak transient overload current reaches 8.5Arms for short-time acceleration and deceleration load. Operating ambient temperature ranges from 0℃ to 55℃; storage temperature ranges from -20℃ to 85℃; working relative humidity ≤80%RH without condensation. With IP20 protection grade, the drive can only be installed inside control cabinet and shall avoid environments with corrosive gas, heavy dust and oil mist. It adopts IGBT sine-wave PWM drive and receives ±10VDC analog command signal from Yasnac CNC controller.

Three optional control modes including speed, position and torque control are available. Key parameters such as servo loop gain and electronic gear ratio are solidified and locked under Y230 customized program; unauthorized parameter modification will result in abnormal motor running or axis positioning deviation. Built-in anti-interference circuit ensures stable incremental encoder signal transmission under complicated industrial electromagnetic interference.Comprehensive protection functions cover overcurrent, overvoltage, undervoltage, overheat, regenerative circuit fault, encoder signal loss and CPU abnormal protection. Single seven-segment digital display on front panel shows real-time running status and numeric fault codes; terminals P and N are reserved for external regenerative braking resistor connection.

R, S, T terminals connect three-phase input power source; U, V, W terminals link power cables of matched USAF servo motor; PE terminal must connect reliable protective ground complying with local electrical safety codes; P/N terminals are available for external brake resistor wiring.Control terminal block accepts ±10VDC analog instruction from CNC system, digital input signals for servo enable and fault reset, and dry-contact relay output provides external fault alarm feedback. Special circular aviation connector follows SS-Y230 customized pin definition for incremental encoder wiring.

Mount the servo vertically inside electrical cabinet and reserve sufficient top and bottom clearance for heat dissipation, keeping away from heat-generating components such as transformers and contactors. Complete full wiring inspection before power-on to avoid short-circuit damage. Pre-locked Y230 factory parameters allow direct replacement without extensive parameter tuning. Perform no-load jog test to verify motor rotation direction and running stability prior to mechanical load connection.

Cut off all input power and wait over 10 minutes for internal capacitor residual high voltage discharge before maintenance work to prevent electric shock hazard. Clean cooling vents and retighten loose terminal screws every three months regularly. Once fault alarm appears, check sequentially input power fluctuation, motor mechanical jamming, loose encoder wiring and insufficient cabinet heat dissipation; repeated power-on is forbidden before all faults are fully eliminated, and arbitrary revision of locked Y230 customized parameters is strictly prohibited.
