Description

The YASKAWA CACR-SR07BE12M is a high-performance, compact servo drive from Yaskawa’s Sigma-7 series, engineered for precision motion control in industrial automation. Designed to pair seamlessly with Yaskawa’s SGM7G and SGM7J servo motors, this drive delivers exceptional responsiveness, accuracy, and energy efficiency for dynamic applications. The CACR-SR07BE12M integrates advanced auto-tuning algorithms, real-time vibration suppression, and 24-bit high-resolution encoders to achieve sub-micron positioning precision. Its core function involves converting control signals into precise torque/speed commands while managing regenerative energy and communication with PLCs or motion controllers via EtherCAT or MECHATROLINK-III protocols.

Positioned as a mid-power solution (0.75 kW), this drive excels in space-constrained installations with its slim 30mm width. The “BE12M” suffix indicates single-phase 100–120VAC input and dynamic brake support – critical for vertical axis control. The YASKAWA CACR-SR07BE12M reduces machine commissioning time through one-touch tuning and adaptive filter technology, while its IP20-rated housing ensures reliable operation in panel-enclosed environments. For engineers seeking to optimize cycle times and minimize overshoot in high-acceleration systems, this drive represents a balance of power density and intelligent motion optimization.

Technical Specifications

Main Features and Advantages

Intelligent Tuning & Vibration Control: The YASKAWA CACR-SR07BE12M features Advanced Vibration Suppression Control II (AVCS+) technology, which autonomously identifies and dampens mechanical resonance frequencies in real-time. This eliminates manual filter tuning and prevents settling delays in cantilevered loads or flexible couplings. Combined with One-Touch Tuning, the drive achieves optimal servo gains in <5>

High-Density Power Design: Despite its compact footprint, the drive delivers 300% overload capability for instantaneous torque bursts during rapid starts/stops. The integrated dynamic brake circuit manages regenerative energy without external resistors (up to 0.75kW), reducing wiring complexity. SiC (Silicon Carbide) power semiconductors minimize switching losses, cutting heat generation by 25% and enabling side-by-side installation without derating.

Seamless Integration: Native EtherCAT support (via CACR-SE02BE option card) enables ≤100μs cycle synchronization with PLCs like the Yaskawa MP3300. The SigmaLogic+ function allows custom sequencing within the drive, offloading simple motion tasks from central controllers. Dual safety inputs (STO/SBC) comply with SIL 3/PLe standards, while configurable I/O (4 digital in/2 digital out) supports sensors and interlocks.

Application Field

The YASKAWA CACR-SR07BE12M drives precision motion in high-speed automation:

Robotics: Controls SCARA arms (e.g., Yaskawa HC10) for electronics assembly, ensuring ±0.01mm repeatability during PCB component placement.

Packaging Machinery: Synchronizes rotary cutters and fillers in food/beverage lines, maintaining phase alignment at >200 cycles/minute.

Semiconductor Handling: Positions wafer transfer robots in vacuum environments using low-outgassing SGM7G motors.

Medical Devices: Drives liquid dispensing pumps in diagnostics equipment with pulsation-free flow control.

Machine Tools: Powers tool changers and ATC arms, leveraging the brake function for vertical axis holding.

In automotive welding lines, the CACR-SR07BE12M coordinates servo-press force profiles, while its EtherCAT daisy-chaining simplifies cabinet wiring. For textile machinery, it enables tension-controlled winding with automatic inertia compensation during material spooling.
