CACR‑SR15BZ1SF（Yaskawa VS‑800 / SERVOPACK）
CACR-SR15BZ1SF is an AC servo drive from Yaskawa VS-800 (CACR-SR) series with a rated power of 1.5 kW. It adopts three-phase 200 VAC power input, features Z-type dedicated encoder interface, standard I/O terminals and general standard firmware. This model is widely used for maintenance and retrofitting of old CNC machines and traditional automation equipment. It has been discontinued by the manufacturer, and only used or fully refurbished units are available on the market.
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 the drive is compatible with Yaskawa B-series servo motors. Letter Z indicates Z-type exclusive encoder interface. Digit 1 denotes three-phase 200 VAC input specification. Letter S stands for standard input and output ports. Letter F represents standard general-purpose firmware without custom modification.
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 also 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 current reaches 28 A.
This drive supports analog speed control via ±10 VDC signal and torque control. Position control with pulse command is optional. It matches standard incremental encoder with Z-type interface. The speed regulation ratio is 1:3000, and the load regulation rate is lower than 0.01% at rated speed. It is equipped with RS-232C and RS-485 communication ports supporting Modbus RTU protocol.
The drive is designed for vertical panel mounting. The operating ambient temperature ranges from 0°C to 45°C, and the storage temperature is between -20°C and 60°C. The relative humidity shall not exceed 90 percent, and condensation is not allowed. Built-in protection functions include overcurrent, overvoltage, undervoltage, overheat, encoder fault and overload protection.
Comparison with Similar 1.5 kW Models
CACR-SR15BZ1SF is fitted with standard F firmware, standard S-type I/O and Z-type encoder interface, mainly applied to equipment using analog control. CACR-SR15BY1SG-E uses standard E firmware, standard G-type I/O and Y-type encoder interface for general CNC equipment with pulse and analog control. CACR-SR15BY1SG-Y72 adopts Y72 custom firmware and standard G-type I/O for special customized machine tools. CACR-SR15BY1SS-Y49 and CACR-SR15BY1SS-Y50 are equipped with enhanced S-type I/O and dedicated firmware, which are suitable for high-end CNC systems.
Typical Applications
It is commonly installed on legacy CNC lathes and milling machines with analog speed control. It also applies to industrial robots, rotary tables and material handling equipment. This model is an ideal replacement for faulty units of old VS-800 servo systems that require Z-type encoder interface.
Product Availability & Warranty
Original production has been terminated. Current supplies are tested second-hand and refurbished products. The general warranty period ranges from 6 to 12 months. It is a cost-effective choice for equipment repair and spare part replacement.
