CACR-SR05BB1BF
CACR-SR05BB1BF is a classic 0.5kW analog SERVOPACK servo amplifier under Yaskawa CACR-SR series, specially developed to match YASNAC VS-800 original CNC control system for vintage Japanese CNC lathes, tapping machines and small vertical machining centers. It adopts BB-version original mainboard hardware layout with optimized BF customized firmware design, belonging to general adjustable parameter model without fixed OEM parameter lock, differing from Y-suffix locked parameter variants like CACR-SR05BB1AM-Y114. This drive is designated for pairing with Yaskawa USAGED/USAREM-05 500W servo motor equipped with standard 1000P/R incremental A/B/Z phase encoder, which is the core specification difference versus AM-type drives for 6000P/R high-resolution encoder motors. Designed with ±10VDC analog command input structure, it realizes full closed-loop three-loop control of position, speed and torque linked directly with VS-800 CNC host controller.

2. Model Code Definition
CACR stands for Yaskawa traditional analog AC servo driver general series; SR means analog ±10V instruction input type exclusively supporting VS-800 numerical control system; 05 refers to rated continuous output power 0.5 kilowatt; BB represents BB revision PCB mainboard circuit specification; digit 1 stands for single-channel incremental encoder feedback CN2 interface; BF is specification code matching 1000PPR standard incremental encoder servo motor with fully open adjustable factory parameters and no pre-solidified parameter restriction.
3. Core Electrical Specifications
Main circuit power supply requires three-phase AC 200V~230V with allowable voltage fluctuation +10%/-15%, compatible with 50Hz and 60Hz input frequency; control power uses independent separated single-phase AC 200V~230V power source to isolate power interference from main loop. Rated continuous output current reaches 4.2Arms, transient peak overload current hits 11.0Arms with effective overload duration within 3 seconds. Internal power conversion applies IGBT sine-wave PWM inversion driving technology, equipped with natural air convection cooling design without built-in cooling fan. Front-mounted single seven-segment digital display realizes real-time running status monitoring and fault alarm code prompt for field maintenance diagnosis.
4. Connector Functional Description
CN1 control signal connector receives analog speed/position command signal from VS-800 CNC system, meanwhile reserves terminals for external torque limit analog input, servo enable digital input, fault reset input and servo ready relay dry contact output; shielded cable wiring is recommended for all analog signals to restrain electromagnetic interference. CN2 exclusive feedback port connects A/B/Z phase pulse signal of 1000P/R incremental encoder on matched servo motor, open circuit or wrong wiring will trigger encoder disconnection protection alarm after power on. Main terminal block is arranged with R/S/T three-phase main power terminals, U/V/W motor output terminals, external regenerative brake resistor wiring terminals and safety grounding terminal as standard configuration.
5. Key Product Features
The biggest advantage of BF model is full free parameter modification permission, all gain parameters, electronic gear ratio, encoder resolution and load matching parameters can be arbitrarily modified on-site according to actual mechanical condition after factory reset, unlike customized Y-suffix locked parameter drives. Complete multi-layer safety protection is integrated including overcurrent, overvoltage, undervoltage, internal overheat, encoder loss and continuous overload protection to avoid sudden equipment damage under abnormal working conditions. Standard IP20 protection grade, whole machine net weight around 1.5kg, applicable working ambient temperature range 0℃~55℃, storage temperature -20℃~85℃, working environment relative humidity below 80% without condensation, maximum allowable installation altitude 1000 meters above sea level, must be vertically installed inside closed electrical cabinet.
6. Application Scope
Mainly used as original replacement spare part for old Japanese CNC machine tools equipped with VS-800 control system and 1000PPR encoder 500W servo motor; also applicable for ordinary industrial automation retrofitting with analog ±10V command control requirement due to adjustable parameter design, can flexibly match different load mechanical structures after parameter fine-tuning, wider application compatibility compared with fixed-parameter Y114 customized servo products.
7. Installation & Maintenance Tips
Complete all wiring operation under full power-off state and wait more than 10 minutes for internal capacitor full discharge before opening the unit shell to prevent electric shock risk. Reserve sufficient ventilation gap around drive during cabinet installation to guarantee natural heat dissipation effect. Periodically clean dust on heat sink surface every six months, check cable aging and terminal fastening condition regularly; avoid direct high-pressure air blowing into internal PCB during cleaning to prevent conductive dust short-circuit failure.
