1. Product Overview

2. Model Code Definition

• CACR: Yaskawa standard code for AC servo amplifier

• SR: Basic speed-control platform, configurable for position / torque control via internal parameters

• 03: Rated output 0.3kW, compatible with Yaskawa 300W USAM/USAF series servo motors

• BB1: Main power board specification, 200V input grade + fixed terminal layout design

• HS: Custom control board variant: dedicated incremental encoder receiving circuit, exclusive analog command matching logic, factory locked partial application parameters differing from CS/ES/BF variants

3. Core Electrical Specifications

• Power Input: 3-phase AC 200~230V (+10%/-15%), 50/60Hz; independent single-phase AC200~230V for control power supply

• Output Rating: Continuous rated current 3.0Arms, peak overload current 8.5Arms for rapid acceleration & deceleration

• Ambient Condition: Operation temp: 0℃~55℃; storage temp: -20℃~85℃; RH ≤80% non-condensation; IP20 protection for cabinet indoor installation only

• Drive Technology: IGBT sine-wave PWM modulation for smooth low-vibration motor operation

4. Main Control Functions

1. Three available control modes: speed / position / torque control; partial parameter locked by HS factory preset to guarantee matching original host CNC system, random parameter modification forbidden.

2. Optimized anti-interference encoder signal processing on HS control board, stronger EMC performance for workshop with severe power interference.

3. Complete multi-protection system: over-current, over/under voltage, overheat, encoder loss, regenerative fault, CPU abnormal shutdown protection.

4. Front-panel single 7-segment digital display: real-time running status + numeric fault alarm codes for fast troubleshooting; reserved P/N terminals for external dynamic braking resistor connection for high frequent start-stop loads.

5. Wiring Description

• Main Circuit Terminals: R/S=T-phase power input; U/V/W=connect servo motor three-phase winding; PE=protective earth per local electrical safety standard; P/N=external brake resistor access

• Control Terminal: ±10VDC analog command input receives speed/position instruction from Yasnac VS-800 CNC; digital I/O for servo enable & fault reset; dry-contact relay output for external fault alarm feedback; dedicated round aviation connector for HS-spec encoder cable wiring.

6. Installation & Commissioning

• Vertically mount inside electrical cabinet, reserve upper/lower ventilation gap, avoid installation near heat sources like transformer/contactor; multiple drives need forced air cooling.

• Full wiring inspection before power-on to eliminate short-circuit risk; HS model with factory fixed parameters, no full parameter initialization needed for replacement installation; perform no-load jog test first to verify rotation direction & stability before mechanical load connection.

7. Maintenance & Fault Handling

• Cut off main power and wait ≥10 mins for capacitor full discharge before disassembly/maintenance to avoid electric shock hazard.

• Quarterly routine maintenance: clean cooling vents & fasten terminal screws to prevent loose contact caused by long-term vibration.

• Once alarm code appears, check sequentially: input power fluctuation, motor mechanical jamming, loose encoder wiring, cabinet overheating; stop repeated startup until root failure is removed, do not rewrite locked HS customized parameters arbitrarily.
