1. Product Introduction

2. Full Model Definition

• CACR: Yaskawa AC servo amplifier general code

• SR: Triple-control platform (speed / position / torque control configurable via parameters)

• 03: Rated driving power: 0.3kW / 300W

• BZ: Mainboard dedicated for ABSOLUTE ENCODER feedback (core difference vs BB/BY/BE; supports absolute position motor, no zero return after power-off)

• 1S: S-type customized control PCB, fixed base program for Yasnac analog ±10V command

• F: Encoder circuit for standard USAF incremental/absolute motor, 1000PPR encoder specification

3. Electrical Specifications

• Main power input: 3Φ AC200~230V, ±10%/-15%, 50/60Hz; control power: independent single-phase AC200~230V

• Rated continuous output current:3.0Arms; peak overload:8.5Arms

• Working ambient temp:0℃~55℃; storage:-20℃~85℃; Humidity ≤80%RH non-condensing, IP20 cabinet installation only

• Drive mode: IGBT sine-wave PWM modulation, natural air cooling for small power unit

4. Core Features & Protection

1. Analog ±10VDC speed/position command input for Yasnac CNC controller; dry-contact fault relay output, digital IO for servo enable/reset

2. Complete protection: OV, UV, overcurrent, overheat, encoder loss, regenerative fault, CPU error; single 7-segment LED for fault code display

3. P/N terminals reserved for external regenerative brake resistor wiring

4. BZ exclusive advantage: Absolute encoder matching, saves machine origin reset after power cut

5. Wiring Rule

• R/S/T: 3-phase main power; U/V/W: motor power output; PE mandatory grounding

• Round dedicated aviation connector for absolute encoder wiring (BZ dedicated pinout, different from BY/BE version)
