1. Model Code Definition

2. Electrical Ratings

• Main Input Power: Single/Three-phase AC200~230V, +10%/-15%, 50/60Hz

• Continuous Output Current: 3.0Arms; Peak Overload Current: 8.5Arms

• Matching Servo Motor: Yaskawa USAMED-03 / USAFED-03 (300W), default matched with 6000PPR incremental encoder; supports optional 5000/4000PPR encoder by parameter setting

• Control Mode: 3 closed-loop control (Current Loop + Speed Loop + Position Loop); freely switchable between analog speed / pulse position / torque control via internal potentiometer & parameter adjustment

• Output: 3-phase IGBT sine-wave PWM output to motor U/V/W terminals

3. Terminal & Connector Layout

Main Power Terminals

• R, S: Main AC power input terminals; reserved terminals for external dynamic braking resistor connection

• U, V, W: 3-phase power output to servo motor stator windings

Control Connectors

• CN1 (50Pin): Standard universal pin assignment for servo enable, ready output, fault alarm, CNC interlock signals (general standard definition, not custom OEM wiring like Y-suffix variants)

• CN2 (20Pin): Standard incremental encoder feedback port for 6000/5000/4000PPR PG wiring

4. Environmental & Mechanical Specifications

• Operating Ambient Temp: 0℃ ~ +55℃; Storage Temp: -20℃ ~ +85℃

• Relative Humidity: ≤95%RH, non-condensing; Max installation altitude ≤1000m above sea level

• Protection Grade: IP20 (cabinet indoor installation only)

• Cooling Method: Natural convection cooling; Net weight ≈2.9kg

5. Core Features of Standard M Version

1. All speed/position loop gain, electronic gear ratio parameters unlocked, adjustable via front potentiometers (VR1~VR6 for zero drift, loop gain, max current setting)

2. I/O signal polarity, enable logic can be modified by internal parameter adjustment, no factory firmware lock

3. Manual jog mode & command source switching available for field test; compatible with most standard VS-800 CNC machine tools without dedicated rewiring

4. Universal replacement: can substitute CACR-SR03BB1AF standard model after simple parameter tuning; cannot directly replace Y-custom suffix(Y114/Y338) without CN1 re-wiring

6. Protection & Fault Alarm Codes

Reset: Cut off main power ≥30s after troubleshooting before restart

7. Power-On & Replacement Guide

1. Pre-power inspection: Confirm R/S input, U/V/W motor, CN2 encoder wiring no short/open circuit

2. Power sequence: CNC cabinet control power first → servo main AC power; standby display shows fixed digit with no alarm for normal status

3. Replacement rule:

   • Direct plug & play: only same model CACR-SR03BB1AM

   • CACR-SR03BB1AF available as alternative after parameter reset & potentiometer calibration

   • Y114/Y338 custom drive cannot direct swap, need full CN1 re-pin wiring
