This unit is an AC servo drive manufactured by Yaskawa Electric. The rated output power is 0.3kW. The Y114 suffix indicates a factory-customized version exclusively designed for CNC machine tools, paired with USAM or USAF series servo motors.

The drive accepts three-phase AC input ranging from 200V to 230V at 50Hz or 60Hz. It supports three closed-loop control modes: speed control, position control and torque control. The encoder feedback circuit is customized per Y114 specification for matched servo motors.The equipment shall be installed vertically inside control cabinets with sufficient ventilation space on upper and lower sides. Operating environment is limited to indoor locations with ambient temperature between 0°C and 45°C; corrosive gas, excessive dust and oil mist are prohibited.Built-in protective functions cover overcurrent, overvoltage, undervoltage, overheat, regeneration circuit error and main controller malfunction protection.

CACR stands for Yaskawa standard AC servo amplifier series. SR denotes speed-control base model with optional position and torque control functions. Digit 03 corresponds to 0.3kW rated output capacity. BB1 indicates hardware revision and power terminal layout. AM specifies control circuit design and encoder interface definition. Y114 is the unique custom code for CNC dedicated modification.

Terminals R, S and T are used for three-phase main power input. U, V and W terminals connect to three-phase power leads of the servo motor. Terminals P and N are for external regenerative braking resistor connection. The protective earth terminal must be securely wired to cabinet ground for safety.Control terminals consist of ±10VDC analog speed command input, digital input pins for drive enable and fault reset, dry-contact fault output terminals and a dedicated connector for encoder feedback wiring.

Verify all wiring and ground connections thoroughly before powering on the drive to prevent short circuit or wrong wiring damage. Complete parameter configuration based on actual motor and machine application before formal operation.When an alarm code occurs during operation, inspect mechanical jamming, unstable input voltage, motor insulation status and loose wiring step by step. Always cut off the main power source prior to any wiring adjustment or maintenance work.
