CACR-PR07BCAF
CACR-PR05BCAF is a 0.5kW DIN-rail mounted AC servo amplifier from YASKAWA CACR-PR legacy series. It is a dedicated digital positioning servo designed to pair with USA-series incremental encoder servo motors including USAMED, USAFED and USASEM. The servo integrates power and control circuitry in one compact unit with front digital display and status indicator lamps for real-time status monitoring and fault indication. When assembled with optional CPCC-PP100 positioning module, it realizes independent point-to-point positioning without external PLC or pulse controller. Equipped with comprehensive built-in protection circuits, this discontinued model is mainly supplied as original replacement spare for overhaul and retrofit of aged CNC machines, packaging lines and general factory automation equipment.
Description
1. Product Brief Introduction
CACR-PR05BCAF is a 0.5kW DIN-rail mounted AC servo amplifier from YASKAWA CACR-PR legacy series.

2. Model Code Definition
CACR stands for YASKAWA AC servo drive series code. PR denotes rack-type servo with embedded positioning control and DIN35 rail mounting structure. 05 represents rated output power of 0.5kW. B specifies three-phase AC200V input and cabinet optimized hardware layout. C refers to compatibility with standard 1500P/R incremental encoder for matched servo motors. AF indicates unique hardware revision, terminal definition and internal protection configuration of this specific variant.
3. Technical Parameters
Electrical specs: three-phase AC200V~230V input, 50/60Hz; rated output power 0.5kW, rated output current 4.8A; sine-wave PWM vector control with speed and position dual closed loop, matching 1500P/R incremental encoder motors.Environmental specs: operating temperature -10℃ to +55℃, storage temperature -20℃ to +60℃; ambient humidity 20%~80%RH non-condensing, free of corrosive gas; IP20 protection for cabinet installation; max installation altitude ≤1000m; standard DIN35 rail fixing.
4. Interface and Communication Configuration
Main power terminals L1/L2/L3 for three-phase incoming power, U/V/W for motor power output and PE for protective earthing. CN1 control connector includes multi-channel digital inputs for servo enable, fault reset and mode selection, digital outputs for ready signal and fault alarm, plus ±10V analog speed command input. CN2 is dedicated encoder port for A/B/Z feedback signals and encoder power supply.Onboard RS422 communication uses exclusive YASKAWA proprietary protocol with selectable 4800bps and 9600bps for parameter setting and field debugging. No native Modbus or CANopen; extended positioning bus function requires external CPCC-PP100 module.
5. Core Functions
Two selectable operation modes: speed control and positioning control switched via external control terminals. Combined with CPCC-PP100 module, the unit performs standalone fixed-point positioning without upper pulse instructions. Full protection covers overcurrent, overvoltage, undervoltage, overload, overheat, encoder breakage and output short-circuit; servo shuts down and displays fault code upon abnormality. Built-in auto-tuning automatically identifies motor parameters to improve low-speed stability and dynamic response. Adjustable torque limit prevents mechanical collision from overload, while onboard self-diagnosis enables fast troubleshooting via front digital display.
6. Application Scenarios
Used for feed axis drive of traditional CNC lathes and milling machines; positioning drive of food & pharmaceutical packaging machinery; winding and conveying control for textile equipment; precision transport drive for electronic assembly machines; spare part replacement and refurbishment of obsolete imported automation lines and legacy small precision semiconductor processing equipment.
7. Operation and Maintenance Instructions
Install the servo inside well-ventilated control cabinet away from dust, moisture and corrosive gas to ensure proper heat dissipation. Verify all power, control and encoder wiring correctness before power switch-on to avoid burnout from wrong connection. Configure parameters according to motor rating and actual mechanical load during initial commissioning. Always cut off main power before routine inspection or disassembly maintenance. Periodically fasten loose terminals and wipe dust from the unit surface. In case of fault codes, power off first and check relevant wiring and mechanical structure as per fault information before restarting the equipment.
