CACR-SR15SB1AF
CACR-SR15SB1AF is a 1.5 kW AC servo drive from Yaskawa classic VS-800 (CACR-SR) series. It features three-phase 200 VAC power input and is designed to work with Yaskawa S-series servo motors. Equipped with standard encoder interface, regular I/O ports and AF standard general firmware, this legacy model has been discontinued by the manufacturer. At present, only tested second-hand and fully refurbished units are available for equipment maintenance and spare part replacement.
Description
Model Number Explanation
CACR stands for AC Servo Drive, also known as SERVOPACK. SR represents the speed and position control type of the VS-800 series. The number 15 indicates the rated power of 1.5 kW. Letter B means the drive is compatible with Yaskawa S-series servo motors. Digit 1 refers to three-phase 200 VAC input specification. Letter A denotes standard encoder interface. The suffix AF stands for standard general-purpose firmware without customized programming.
Main Technical Specifications
The main power supply is three-phase 200 to 230 VAC with a frequency of 50 Hz or 60 Hz, and the control circuit uses single-phase 200 to 230 VAC. 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 three common control modes: ±10 VDC analog speed control, torque control and pulse-based position control. It pairs with standard incremental encoders. The speed regulation ratio is 1:3000, and the load regulation rate is lower than 0.01% under rated speed. It is built with RS-232C and RS-485 communication interfaces that support Modbus RTU protocol for parameter setup and data transmission.
The unit adopts vertical panel mounting. The operating ambient temperature is 0°C to 45°C, and the storage temperature ranges from -20°C to 60°C. The relative humidity shall not exceed 90 percent, and condensation is strictly prohibited. Integrated protection functions include overcurrent, overvoltage, undervoltage, overheat, encoder fault and overload protection to ensure safe and stable operation.
Core Features
It adopts mature and reliable hardware structure together with stable AF standard firmware, which ensures long-term continuous operation. Universal control modes and standard interfaces provide good compatibility with most traditional CNC machines and general automation equipment. The whole unit is easy to install, wire and debug, effectively lowering the difficulty of on-site maintenance.
Differences from CACR-SR15SB1A/BF
These two models share the same power rating, voltage, motor compatibility, encoder and I/O configuration. The only difference lies in the firmware version. CACR-SR15SB1AF uses AF standard firmware, while CACR-SR15SB1A/BF adopts A/BF firmware. Both are general-purpose versions, with minor parameter tuning differences to match different types of original equipment.
Typical Applications
It is widely applied to conventional CNC lathes, milling machines and other machine tools. It also fits medium and small automation equipment such as conveyor lines, rotary tables and material handling systems. It is a preferred replacement part for faulty drives in legacy VS-800 servo systems matched with S-series motors and AF firmware.
Availability & Warranty
Original production has been terminated. All available products are strictly inspected used units and refurbished products. The standard warranty period is 6 to 12 months. It is an economical and practical choice for the maintenance and renovation of old production lines.
