Description
Product Overview
CACR-SR15BZ1SM is a 1.5 kW AC servo drive belonging to Yaskawa VS-800 CACR-SR series. It features three-phase 200 VAC power input, Z-type dedicated encoder interface and standard input and output terminals. Equipped with modified M-type firmware, this unit is specially tuned for legacy CNC machines and dedicated automation equipment. The model has been discontinued by the manufacturer, and only tested second-hand and refurbished units are available in the current market.
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 refers to the rated power of 1.5 kW. Letter B means the drive is fully compatible with Yaskawa B-series servo motors. Letter Z indicates the adoption of exclusive Z-type encoder interface. Digit 1 stands for three-phase 200 VAC input specification. Letter S represents standard I/O ports. The final letter M means modified firmware customized for specific industrial machines.
Main Technical Specifications
The main power input is three-phase 200 to 230 VAC with a working frequency of 50 Hz to 60 Hz, and 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 reaches 28 A.
This servo drive supports analog speed control via ±10 VDC signal and torque control, and pulse-based position control is available as an optional function. It works with standard incremental encoders matched for Z-type interface. The speed regulation ratio is 1:3000, and the load regulation rate stays below 0.01% under rated speed. It is built with RS-232C and RS-485 communication ports that support Modbus RTU protocol.
The unit adopts vertical panel mounting. The operating ambient 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 percent, and condensation is strictly prohibited. Complete protective functions include overcurrent, overvoltage, undervoltage, overheat, encoder fault and overload protection.
Differences from Similar Model CACR-SR15BZ1SF
Both CACR-SR15BZ1SM and CACR-SR15BZ1SF share the same power rating, voltage specification, Z-type encoder interface and standard I/O configuration. The core difference lies in the built-in firmware. CACR-SR15BZ1SF uses standard F-type general firmware for universal analog control applications. CACR-SR15BZ1SM applies modified M-type firmware, which is optimized for specific old CNC machine tools and customized production equipment.
Typical Applications
This drive is mainly applied to legacy CNC lathes and milling machines that rely on analog speed control. It also fits for industrial robots, rotary working tables and material handling systems equipped with Z-type encoders. It serves as a direct replacement for faulty VS-800 servo drives which require Z-type encoder interface and M-type modified firmware.
Product Availability & Warranty
Original production has been stopped. All available products are fully inspected used units and refurbished products. The standard warranty period is 6 to 12 months. It is a reliable and cost-effective solution for equipment maintenance and spare part replacement.
