CACR-SR02AC1ER-Y27 Detailed Parameters + Model Analysis + Usage Instructions 1. Model Disassembly CACR-SR02AC1ER-Y27 • CACR-SR: Yaskawa VS-800 Series, Older Model Servo Drive • 02: Rated Power 0.2kW (200W) • AC: Body Structure Specifications, Installation Dimensions, Current Model Grade (Different from AB Models) • 1ER: Standard Control Firmware Version • Y27: Customized Internal Parameters, Acceleration and Deceleration, Gain, IO Logic are all Customized and Fixed, Cannot be Directly Replaced with Ordinary 1ER 2. Core Electrical Parameters • Input Power: Three-phase AC 200V - 230V, 50/60Hz • Rated Power: 200W / 0.2kW • 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 0.2kW Incremental Encoder Servo Motors 3. Hardware Appearance and Structure • The appearance, installation holes, terminals, and interface layout of the same series CACR-SR02AC are completely universal • The body size and installation position of this model are slightly different from the AB model, AC can only be interchanged with AC models • Front: Digital Display + Operating Keys • Side Nameplate: Printed with CACR-SR02AC1ER-Y27, Voltage, Power, Serial Number, Made in Japan

IV. Interface Terminal Description 1. Main Circuit Terminals R/S/T: Three-phase power input U/V/W: Connect to servo motor  • /-: DC bus, can be externally connected with braking resistor  2. CN1 Control Socket: Servo enable, alarm output, positioning completion, pulse instruction, ±10V speed instruction, 24V power signal  3. CN2 Encoder Socket: Compatible with motor incremental encoder A/B/Z phase signals, 5V power supply  V. Key Points for Use & Replacement 1. Y27 is a customized special version with internal parameters and logic locked. Ordinary CACR-SR02AC1ER without Y27 cannot be directly installed and used, it will trigger alarms, inaccurate positioning, and logical abnormalities. 2. Normal power-on: Digital tube displays 0; Reports numbers 1 to 9 correspond to overcurrent, overvoltage, undervoltage, overheating, encoder failure, etc. 3. Replacement priority: The most reliable method is to replace with the same model CACR-SR02AC1ER-Y27 exactly.
