1. Product Overview

2. Model Code Definition

• CACR: Yaskawa standard AC servo amplifier series code

• SR: Basic speed platform, supports speed/position/torque 3 control modes via parameter setting

• 03: Rated output power 0.3kW (0.4HP)

• BE: 200V-grade dedicated main power board specification

• 12: Standard universal encoder interface circuit, 12-core aviation connector definition for incremental encoder

• G-E: Standard G-version factory preset parameter program, E = export general specification without special OEM locked parameters

3. Electrical Specifications

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

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

• Ambient working temp:0~55℃; storage temp:-20~85℃; working humidity ≤80%RH non-condensing; IP20 protection, cabinet vertical installation only

• Drive mode: IGBT sine-wave PWM modulation

4. Core Control Features

1. Standard ±10VDC analog speed/position command input for Yasnac CNC host, G-version universal parameters, free parameter modification available without factory lock limit

2. Complete protection: overcurrent, overvoltage, undervoltage, overheat, encoder loss, CPU fault protection; front single digit tube display for fault code inquiry

3. P/N terminals reserved for external regenerative brake resistor connection for high frequent start-stop load

5. Wiring & Commissioning

• Power terminals: R/S-T=3φ input; U/V/W=motor connection; PE=protective grounding; P/N=dynamic braking resistor port

• Control terminal block: analog command input, servo enable, fault reset digital input, dry-contact fault alarm output

• Circular aviation connector for encoder feedback per 12-pin standard definition of BE12 spec

• Before power-on full wiring inspection; standard G parameters need no customized setting during replacement, finish no-load jog test before mechanical assembly
