Description
CACR-SR03AA2AH is an AC servo drive belonging to Yaskawa VS-800 (CACR-SR) series. Its rated power is 0.3 kW (300 W). This unit features 200 VAC single-phase power input, dual control modes of pulse position and analog speed, dedicated encoder interface and panel mounting structure. This classic model has been discontinued by the manufacturer, and only used, refurbished or surplus units are currently available on the market.
Model Number Explanation
CACR stands for AC Servo Drive. SR represents the speed and position control type of VS-800 series. The digit 03 means the rated power is 300 W. Letter A indicates compatibility with Yaskawa R-series servo motors. The second letter A refers to standard hardware revision. Digit 2 denotes pulse command input for position control. The letter A stands for standard incremental encoder interface. The final letter H represents panel mounting type.
Main Technical Specifications
The drive accepts single-phase 200 to 230 VAC input with a working frequency of 50 Hz to 60 Hz. The three-phase output voltage ranges from 0 V to 230 VAC, and the rated output current is 2.0 A. It supports two main control modes, including pulse-based position control and ±10 VDC analog speed control. The matched encoder is a standard 1500 ppr incremental type.
This servo drive is designed for panel mounting and shall be installed vertically. The operating ambient temperature ranges from 0°C to 45°C, and the storage temperature is from -20°C to 60°C. The relative ambient humidity shall not exceed 90 percent, and condensation is strictly prohibited. Built-in protection functions cover overcurrent, overvoltage, undervoltage, overheat, encoder fault and overload protection.
Installation and Wiring
Main circuit terminals R and S are connected to AC power supply. Terminals U, V and W are used for connection with the three-phase servo motor. The PE terminal must be reliably connected to protective earth. The RB terminal is reserved for external regenerative resistor connection according to actual operating requirements.
The control connector integrates pulse command, direction signal, analog speed signal, forward and reverse operation signals, emergency stop and alarm output. The encoder connector is used to connect encoder differential signals and power lines.
Typical Applications
It is widely used in medium small automated equipment, such as packaging machinery, material handling devices, rotary indexing tables and light-load positioning platforms. It is also a common replacement part for the maintenance and upgrade of old VS-800 servo systems.
Product Availability
Original production of this model has been stopped. Most products on sale are fully tested second-hand and refurbished units, which are generally provided with a warranty period of 6 to 12 months. It is a practical and economical solution for equipment repair and spare part replacement.
