CACR-SR03BY1SG-E

CACR-SR03BY1SG-E is a 0.3kW all-digital Yaskawa Yasnac AC Servopack from classic CACR-SR series, G-series customized version exclusively for Yasnac CNC lathe/machining center feed axis control. Discontinued original production, mainly used as maintenance replacement spare parts, matched with Yaskawa USAF-G series 300W incremental encoder servo motor. Suffix E = standard OEM export version (no factory parameter lock, editable internal parameters).

Description

1. Product Overview

CACR-SR03BY1SG-E is a 0.3kW all-digital Yaskawa Yasnac AC Servopack from classic CACR-SR series, G-series customized version exclusively for Yasnac CNC lathe/machining center feed axis control. Discontinued original production, mainly used as maintenance replacement spare parts, matched with Yaskawa USAF-G series 300W incremental encoder servo motor. Suffix E = standard OEM export version (no factory parameter lock, editable internal parameters).

2. Model Code Definition

  • CACR: Yaskawa AC servo amplifier general series code

  • SR: Multi-mode control platform (speed / position / torque adjustable by parameters)

  • 03: Rated output power 0.3kW(300W)

  • BY: 200V-class customized main power board, dedicated power circuit different from BB/BE types

  • 1S: S-type customized control motherboard with fixed basic program

  • G: G-series dedicated encoder circuit, matching USAF-G servo motor feedback

  • E: Standard universal OEM version, parameters not locked by factory (free parameter modification available)

3. Electrical Ratings

  • Main power: 3-phase AC 200~230V, ±10%/-15% tolerance, 50/60Hz

  • Control power: Independent single-phase AC 200~230V

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

  • Ambient working temp:0℃~55℃; storage:-20℃~85℃; Humidity ≤80%RH non-condensing

  • Protection grade: IP20 (cabinet-only installation), IGBT sine-wave PWM driving

4. Core Functions & Protection

  1. Three optional control modes: speed, position, torque via parameter setting; E version allows full parameter tuning unlike C locked version

  2. Complete protection: overcurrent, overvoltage, undervoltage, overheat, encoder loss, regenerative fault, CPU error protection

  3. Single 7-segment LED display for real-time status & fault alarm codes; P/N terminals reserved for external regenerative brake resistor connection

  4. Optimized anti-interference PCB design for stable analog ±10V command signal from Yasnac CNC controller

5. Wiring Definition

  • R/S/T: 3-phase main AC input; U/V/W: servo motor power output; PE: compulsory protective grounding

  • Control terminal block: ±10VDC analog position/speed command input, digital input for servo enable/fault reset, dry-contact relay fault alarm output

  • Special round aviation connector for G-type encoder wiring (SG dedicated pin assignment)

6. Installation & Commissioning

  • Vertical cabinet mounting, reserve upper/lower clearance for heat dissipation, stay away from heat sources

  • Full wiring inspection before power-up; E-version supports free parameter adjustment during replacement debugging

  • Complete no-load jog test to confirm rotation direction before mechanical load connection

7. Maintenance Tips

Cut off main power and wait ≥10min for capacitor residual high voltage discharge before disassembly. Regularly clean cooling vents and fasten terminal screws quarterly. When alarm occurs, check power supply fluctuation, motor jamming, loose encoder cable and poor heat dissipation sequentially.
