CACR-SR05BB1ES-Y114
CACR-SR05BB1ES is a standard 0.5kW analog SERVOPACK servo amplifier from Yaskawa classic CACR-SR series, designed to cooperate with YASNAC VS-800 analog CNC system for older Japanese CNC lathes and small processing machines. It features BB-version mainboard and universal non-locked firmware; all internal servo parameters can be freely modified and reset to factory defaults without OEM parameter lock restrictions. This drive matches USAREM and USAGED-05 series 500W servo motors fitted with 1000P/R incremental encoders, and realizes speed, position and torque three closed-loop control via ±10VDC analog command from the VS-800 CNC controller.
Description
1. Product Overview
CACR-SR05BB1ES is a standard 0.5kW analog SERVOPACK servo amplifier from Yaskawa classic CACR-SR series, designed to cooperate with YASNAC VS-800 analog CNC system for older Japanese CNC lathes and small processing machines. It features BB-version mainboard and universal non-locked firmware; all internal servo parameters can be freely modified and reset to factory defaults without OEM parameter lock restrictions. This drive matches USAREM and USAGED-05 series 500W servo motors fitted with 1000P/R incremental encoders, and realizes speed, position and torque three closed-loop control via ±10VDC analog command from the VS-800 CNC controller.
2. Model Code Explanation
CACR stands for Yaskawa conventional AC servo amplifier series. SR represents analog control design supporting ±10VDC command input for VS-800 numerical control. 05 means rated output power of 0.5kW. BB refers to exclusive BB revision mainboard circuit different from BA, AY and AD board layouts. Digit 1 indicates the CN2 feedback interface is exclusively for 1000P/R incremental rotary encoder. ES is the standard matching specification for 1000PPR incremental encoder motors with fully adjustable parameters.
3. Electrical Specifications
Main power input is three-phase AC200V~230V with voltage tolerance +10%/-15% and 50/60Hz frequency. Control power uses independent single-phase AC200V~230V isolated from main circuit. Rated continuous output current is 4.2Arms, and peak overload current is 11.0Arms within maximum 3 seconds. The internal circuit uses IGBT sine-wave PWM topology and adopts natural convection cooling without internal cooling fan.
CN1 receives ±10VDC analog speed or position command from VS-800, and also reserves pins for external torque limit input, servo enable, fault reset and servo-ready contact output. CN2 is dedicated to A/B/Z phase pulse feedback from 1000P/R incremental encoder. The main terminal block contains terminals for main power input, motor output, external regenerative brake resistor and protective ground connection.
4. Environmental and Installation Requirements
The unit has IP20 protection rating and shall be vertically DIN-mounted inside enclosed electrical cabinet only. Operating temperature ranges from 0℃ to 55℃, storage temperature from -20℃ to 85℃. Working relative humidity ≤80%RH without condensation, keep away from corrosive gas, dust and liquid splash. Maximum permitted installation altitude is 1000 meters above sea level.
5. Key Features
Open firmware allows flexible adjustment of loop gains, electronic gear ratio and acceleration parameters to fit various mechanical loads, unlike Y-suffix locked customized servo drives. Built-in complete protection covers overcurrent, overvoltage, undervoltage, overheat, encoder break and overload protection; front digital tube displays fault codes for convenient maintenance. Unified BB dimension enables convenient field replacement among compatible BB standard models after parameter tuning.
6. Application Scope
It serves as replacement spare part for maintenance of vintage VS-800-equipped Japanese CNC lathes and tapping machines, and is also widely used in retrofit of small precision automation equipment with ±10V analog control and 1000P/R incremental encoder feedback.
