CACR-SR05AC1ER

CACR-SR05AC1ER is a standard universal 0.5kW(500W) SERVOPACK servo drive of Yaskawa classic CACR-SR series, no OEM locked firmware (without -Yxx suffix). General-purpose analog ±10VDC command servo, compatible with Yasnac VS-800/VS-600 CNC and other analog-type numerical control systems; all servo parameters are fully editable/resetable, no factory parameter lock restriction. Matching motor: Yaskawa USAREM-05 series 500W servo motor with 1000P/R incremental PG encoder.

Description

1. Product Overview

Matching motor: Yaskawa USAREM-05 series 500W servo motor with 1000P/R incremental PG encoder.

2. Model Code Breakdown

CodeDefinition
CACRYaskawa classic AC SERVOPACK servo amplifier series
SR3-mode control(Speed/Position/Torque), ±10V analog command input for CNC analog control
05Rated power: 0.5kW/500W
ACMainboard revision C version, AC200V specification, optimized analog signal circuit vs AB version; internal hardware circuit differs from AB type, terminal definition consistent in most parts
1Feedback circuit for 1000P/R incremental pulse encoder
EIncremental PG feedback specification
RHardware compatible with USAREM-R series servo motor
No suffix-YUniversal open firmware, all parameters freely adjustable & initialized

3. Core Electrical Parameters

  • Power supply: 3Φ AC200~230V(main circuit), 1Φ AC200V(control power), 50/60Hz

  • Rated continuous output:4.2A; Peak overload current:11A

  • CN1: ±10VDC analog speed/position command port; CN2: dedicated 1000P incremental encoder socket

  • Cooling:natural air cooling; IP20(only cabinet installation)

  • Ambient:Operation temp 0~55℃, storage -20~85℃; Humidity ≤80%RH non-condensing; Max altitude ≤1000m

4. Difference vs CACR-SR05AB1ER / -Y19/-Y37 customized models

  1. CACR-SR05AC1ER(standard universal): Mainboard rev.C, open firmware, full parameter modification allowed, general interchangeable for most VS800 machine retrofit.

  2. CACR-SR05AB1ER(AB base): Mainboard rev.B, universal open firmware, older PCB version, interchangeable in most wiring.

  3. AB1ER-Y19/Y37(custom OEM): AB hardware + locked Y-type firmware, parameters write-protected, cannot be replaced directly with AC1ER casually (easy to cause positioning deviation/alarm).

5. Application Scope

General replacement spare part for old Japanese bench CNC lathes with Yasnac VS series analog CNC system, X/Z feed axis retrofitting & universal equipment modification.
