CACR-SR15SB1A/BF
CACR-SR15SB1A/BF is a 1.5 kW AC servo drive from Yaskawa VS-800 (CACR-SR) series. It is powered by three-phase 200 VAC and compatible with Yaskawa S-series servo motors. This model comes with standard encoder interface, regular I/O terminals and standard A/BF general-purpose firmware. It is a mature legacy model and has been officially discontinued. Currently only tested second-hand and refurbished units are available for equipment maintenance and replacement.
Description
Model Number Explanation
CACR refers to AC Servo Drive also named SERVOPACK. SR stands for speed and position control type of VS-800 series. The number 15 represents the rated power of 1.5 kW. Letter B means it is compatible with Yaskawa S-series servo motors. Digit 1 indicates three-phase 200 VAC input specification. The letter A stands for standard encoder interface. The suffix BF means standard A/BF version general-purpose firmware without special customization.
Main Technical Specifications
The main power input is three-phase 200 to 230 VAC with a frequency of 50 Hz to 60 Hz. The control circuit uses single-phase 200 to 230 VAC power supply. The three-phase output voltage ranges from 0 V to 230 VAC. The continuous rated output current is 11.7 A, and the peak output current is 28 A.
This servo drive supports multiple control modes, including ±10 VDC analog speed control, torque control and pulse-based position control. It works with standard incremental encoders and features a speed regulation ratio of 1:3000. The load regulation rate is lower than 0.01% at rated operating speed. It is integrated with RS-232C and RS-485 communication ports that support Modbus RTU protocol for parameter setting and data transmission.
The drive is designed for vertical panel mounting. The operating ambient temperature is between 0°C and 45°C, and the storage temperature ranges from -20°C to 60°C. The relative humidity shall not exceed 90 percent, and condensation is forbidden in all working conditions. Built-in protection functions include overcurrent, overvoltage, undervoltage, overheat, encoder fault and overload protection to guarantee stable operation.
Product Features
It adopts mature hardware design and stable A/BF standard firmware, which delivers reliable performance for long-term continuous operation. The universal control modes make it adaptable to most traditional automation equipment and ordinary CNC machines. Standard encoder and I/O ports ensure good compatibility with original matching motors and peripheral circuits. It is easy to install, wire and debug for on-site use.
Typical Applications
This servo drive is widely applied to ordinary CNC lathes, milling machines and other machine tools. It is also suitable for small and medium-sized automation equipment such as conveyor lines, rotary tables and material handling devices. It is a common replacement part for repairing and upgrading legacy VS-800 servo systems that use S-series motors and A/BF firmware.
Availability & Warranty
Original production has been terminated. Products on the market are mainly fully inspected used units and refurbished products. The general warranty period is 6 to 12 months. It is an economical and reliable choice for spare part replacement and equipment renovation of old production lines.

Model Number Definition
CACR represents AC Servo Drive, also called SERVOPACK. SR refers to the speed and position control series of the VS-800 platform. The number 15 stands for the rated power of 1.5 kW. Letter B denotes compatibility with Yaskawa S-series servo motors. Digit 1 indicates the specification of three-phase 200 VAC input. Letter A means standard encoder interface. The suffix A/BF refers to standard general firmware version without custom modifications.
Main Technical Specifications
The main power input is three-phase 200 to 230 VAC at 50 Hz or 60 Hz, while the control circuit adopts single-phase 200 to 230 VAC power supply. The output is three-phase 0 to 230 VAC. The continuous rated output current is 11.7 A, and the peak output current is 28 A.
This drive supports three mainstream control modes: ±10 VDC analog speed control, torque control and pulse-type position control. It is matched with standard incremental encoders. The speed adjustment range reaches 1:3000, and the load regulation rate is less than 0.01% at rated speed. It is equipped with RS-232C and RS-485 communication interfaces supporting Modbus RTU protocol for parameter configuration and data communication.
It is designed for vertical panel mounting. The operating temperature ranges from 0°C to 45°C, and the storage temperature is from -20°C to 60°C. The relative humidity shall not exceed 90% and condensation is not allowed. Built-in protection functions include overcurrent, overvoltage, undervoltage, overheat, encoder fault and overload protection to prevent equipment damage.
Core Features
