I. Model Disassembly • CACR-SR: VS-800 Series SERVOPACK (the old model has been discontinued, with speed control as the main feature) • 03: Rated power 0.3kW / 300W • AA: AA-shaped housing (specific for analog speed control, not compatible with BY/AY/AZ/BE) • 2: 200V level power specification • AH: Hardware version / configuration code (analog command, Japanese standard)

Control Characteristics (AA2AH Focus) 1. Speed Control (the only mode) ◦ Command: ±10V → Corresponding positive/negative rated speed ◦ Input Impedance: approximately 10kΩ ◦ Speed Loop: Built-in PI, gain / integral time can be parameter-adjusted ◦ No position control function (no pulse input interface) IV. Terminal Wiring (Core) Main Circuit (left terminal panel) • R, S, T: Three-phase AC 200-230V input • U, V, W: Servo motor output • Y3, Y4: External regenerative braking resistor (20Ω/50W) • PE: Protection grounding Control Interface CN1 (50-pin, AA version defined) • DI (input): Servo enable, positive/negative limit, alarm reset • DO (output): Servo ready, speed reached, alarm, zero speed • Analog: SPD_REF (±10V), GND • No pulse instruction interface (AA series dedicated) Encoder Interface CN2 (20-pin) • Incremental encoder signal: A, /A, B, /B, Z, /Z, 5V, GND V. Panel Operation (Digital Tube + 3 Keys) • MODE: Switch display (speed / current / alarm) • UP/DOWN: Parameter selection, value increase/decrease • SET: Enter parameters / Confirm save Common Parameters (factory values) • P00: Speed loop gain → 80 • P01: Speed loop integral time → 15ms • P02: Encoder resolution (1500p/rev) → 1500 • P03: Maximum speed → 3000rpm • P04: Acceleration/deceleration time → 80ms VI. Alarm Codes (Common) • 1: Overcurrent (load short circuit / motor damage) • 2: Overvoltage (power supply too high / regenerative abnormal) • 3: Undervoltage (power supply phase missing / voltage low) • 4: Overheating (cooling不良 / overload) • 5： Overload (load too large / stuck) • 6： Encoder abnormality (open circuit / wiring error) • 7： Limit trigger • A： Servo not ready • B： Parameter error • F： System failure (hardware damage) VII. Installation and Usage Notes 1. Unique housing： Only AA housing model can be replaced (incompatible with other series hole positions / dimensions) 2. Pure analog control： No pulse position function， cannot be directly replaced with BY/BE series with pulse 3. Wiring standard： Power lines and signal lines are separated， encoder line uses twisted shielded wire 4. Load requirements： Continuous load ≤ 100%， short-time peak ≤ 300% (≤ 3 seconds)
