CACR-SR05AD1KR-Y101

CACR-SR05AD1KR-Y101 is a 0.5kW OEM customized locked servo amplifier of classic Yaskawa CACR-SR series, exclusively matched with YASNAC VS-800 CNC controller, originally preinstalled on vintage Japanese CNC lathes/machining centers. -Y101 = dedicated OEM factory-locked firmware, all gain, electronic gear ratio and axis-specific parameters are write-protected; cannot initialize or replace with standard non-Y suffix drives directly, only same Y101 variant is available for field replacement. Matches USAMED-05 series 500W servo motor with 1000P/R incremental encoder.

Description

1. General Introduction

-Y101 = dedicated OEM factory-locked firmware, all gain, electronic gear ratio and axis-specific parameters are write-protected; cannot initialize or replace with standard non-Y suffix drives directly, only same Y101 variant is available for field replacement. Matches USAMED-05 series 500W servo motor with 1000P/R incremental encoder.

2. Model Code Definition

CACR: Yaskawa traditional AC SERVOPACK servo amplifier series
SR: Triple-control (speed/position/torque), ±10VDC analog command input for VS800 CNC system
05: Rated output power 0.5kW (500W)
AD: D-version mainboard, dedicated analog circuit for special OEM machine specification (different from standard AC board)
1: Built-in feedback circuit for 1000P/R incremental rotary encoder only
K: Customized power/inner circuit revision for designated machine OEM
R: Compatible with USAMED-R type servo motor series
-Y101: Exclusive OEM custom code, factory fixed parameter set, parameter lock enabled

3. Electrical Specifications

Main power: 3-phase AC200V~230V, 50/60Hz, tolerance +10%/-15%
Control power: Independent single-phase AC200V~230V
Rated continuous output current: 4.2Arms; peak overload current:11.0Arms
CN1: Receive ±10VDC analog speed/position command from VS-800 CNC; CN2: only for 1000P/R incremental PG feedback, no absolute encoder support
Cooling: Natural air cooling; Protection grade IP20 (cabinet installation only)
Ambient: Operation 0℃~55℃, storage -20℃~85℃; RH≤80% non-condensing; altitude ≤1000m

4. Core Features

Y101 parameter locked firmware: Parameter modification/initialization forbidden by factory setting; wrong replacement causes axis runaway or positioning offset, machine alarm.
Full protection: Overcurrent, overvoltage, undervoltage, overheat, encoder break, overload, regenerative fault protection.
Compact rack-mounted design for standard electrical cabinet installation.
Unique AD+K hardware layout differs from common AC1ER/AC2ER standard models, non-interchangeable without factory parameter rewrite.

5. Application Scope

Original spare replacement & breakdown maintenance for old CNC machines equipped with YASNAC VS-800 control system (mainly Japanese brand lathes); special customized automation equipment with ±10V analog control +1000P/R incremental encoder feedback.
