CACR-SR02AC2ER (Yaskawa VS-800 Series) 1. Model Explanation • CACR-SR: An older model of Yaskawa VS-800 servo drive series • 02: Rated power 0.2kW (200W) • AC: Body structure specification (not interchangeable with AB models) • 2ER: Hardware/Firmware version (different from 1ER, with different control logic and parameter range) • Without Y suffix: General standard version, not customized for machine tools

II. Core Electrical Parameters • Input Power Supply: Three-phase AC 200V - 230V, 50/60Hz • Rated Power: 200W • Rated Output Current: 2.2A • Maximum Overload Current: 6.6A (300% Short-Term Overload) • Control Mode: Position Pulse Control / ±10V Analog Speed Control • Cooling Method: Natural Air Cooling (No Built-In Fan) • Operating Environment: 0 - 45℃, Humidity ≤ 90% No Condensation • Compatible Motors: Yaskawa Older Model 0.2kW Incremental Encoder Servo Motor (e.g. USAREM-02A) • Weight: Approximately 2.85kg III. Appearance and Interfaces • Front: Digital Display (Initial Power On Shows 0) + Operating Keys • Main Circuit Terminals: R/S/T (Power Supply), U/V/W (Motor), +/- (Brake Resistor) • Control Interface: ◦ CN1: IO Signals (Enable, Alarm, Stop, Pulse / Analog Command) ◦ CN2: Encoder (5V, A/B/Z Phase Signals) • Size: Standard Wall Mount Installation, Need to Leave Heat Dissipation Space on All Sides IV. Differences from 1ER Version • 2ER: General Standard Version, Parameter Open and Adjustable, Compatible with Regular Automation Equipment • 1ER: Partially Customized for Machine Tools (e.g. Y3/Y27), Parameters Are Fixed, Cannot Be Interchanged  V. Replacement Precautions • Products of the same series AC body are universal and cannot be exchanged with AB models • 2ER and 1ER Hardware Are Compatible, But Firmware Logic Is Different. Direct Replacement May Cause Alarm or Position Abnormality. Re-tuning of Parameters Is Required
