2. Model Code Definition

• CACR: Yaskawa standard AC servo amplifier series code

• SR: Multi-mode control platform (speed / position / torque adjustable via internal parameters)

• 03: Rated output power: 0.3kW(300W)

• BE: 200V-class main power board, exclusive internal power circuit layout

• 13: 13-pin circular aviation plug for encoder feedback wiring (distinguished from 12-pin version)

• S: Customized S-version control PCB with factory pre-locked dedicated parameters for specific CNC equipment, fixed encoder signal circuit design

3. Core Electrical Specifications

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

• Rated continuous output current: 3.0Arms; peak overload current:8.5Arms (short-time acceleration/deceleration)

• Ambient working temp: 0℃~55℃; storage temp: -20℃~85℃; humidity ≤80%RH (no condensation)

• Protection grade: IP20, cabinet-mounted only; IGBT sine-wave PWM driving technology

4. Control & Protection Functions

1. Three optional control modes: Speed / Position / Torque control; core parameters pre-set & locked by factory for S-version, random parameter modification is forbidden to avoid CNC matching failure.

2. Complete built-in protection: Overcurrent, overvoltage, undervoltage, overheat, regenerative circuit fault, encoder loss, CPU abnormality protection.

3. Front single-digit digital display: Real-time running status + fault alarm codes; terminals P/N reserved for external regenerative brake resistor connection.

4. Optimized anti-interference circuit for stable encoder signal transmission under complex workshop environment.

5. Wiring Description

• Power terminals: R/S/T = 3-phase input power; U/V/W = servo motor three-phase cable; PE = mandatory protective ground per electrical safety standard; P/N = external brake resistor wiring

• Control terminals: Receive ±10VDC analog command signal from Yasnac CNC; digital input for servo enable & fault reset; dry-contact relay output for equipment fault alarm feedback

• Encoder part: Dedicated 13-core round aviation connector complying with S-version pin definition for motor encoder connection

6. Installation & Commissioning

• Vertical installation inside electrical cabinet, reserve upper/lower ventilation gap for heat dissipation, keep away from heat sources like transformers and contactors.

• Full wiring inspection before power-on to prevent short circuit; S-version factory preset parameters support direct replacement without large-scale parameter setup.

• Complete no-load jog test to verify motor rotation direction and running stability before mechanical load connection.

7. Maintenance & Troubleshooting

• Cut off main power and wait ≥10 mins for internal capacitor high-voltage discharge before maintenance for electric shock prevention.

• Quarterly routine maintenance: Clean cooling vents, fasten terminal screws.

• When alarm triggered: Inspect input power fluctuation → motor mechanical jamming → loose 13-pin encoder cable → poor heat dissipation sequentially; prohibit repeated startup before fault elimination.
