Description

The YASKAWA CACR-SR07BE12M is a pre-engineered,factory-terminated servo cable designed specifically for use with Yaskawa’s Sigma-7(Σ-7)series of AC servo systems.This 7-meter(7m)cable provides a complete connection between the SGDV-series servo drive and the SGM7G-series servo motor,combining both motor power conductors and encoder feedback signal lines in a single,high-performance assembly.

Featuring a straight 12-pin connector on the drive end and a right-angle 12-pin connector on the motor end,this cable is optimized for installations where space is limited or routing around enclosures and moving parts is required.The black flexible PVC jacket offers resistance to oil,abrasion,and moderate mechanical stress,making it suitable for industrial automation environments including robotics,packaging machines,CNC equipment,and semiconductor manufacturing.

Each CACR-SR07BE12M cable undergoes rigorous factory testing to ensure signal integrity,shielding effectiveness,and long-term reliability under continuous flexing—critical for dynamic motion applications.

Application Scenarios

At an automotive component factory in Ohio,a robotic arm on a press tending cell began experiencing intermittent encoder errors during high-speed transfers.Maintenance logs showed that the third-axis servo motor cable was pinched during full extension.The original straight-straight cable created excessive bending stress.Engineers replaced it with the YASKAWA CACR-SR07BE12M—a 7m cable with a right-angle motor-side connector.This reduced cable strain by 60%and eliminated kinking.After six months of 24/7 operation,no further communication faults occurred.The lead technician noted,“The right-angle design saved us from re-routing the entire cable track.”In high-cycle automation,cable geometry is as important as electrical performance.

Technical Principles and Innovative Values

Innovation Point 1:The right-angle motor-end connector minimizes protrusion from the motor housing,reducing risk of damage in confined spaces and enabling cleaner cable routing—especially beneficial in multi-axis robots and linear stages.

Innovation Point 2:Dual-layer shielding(foil+braid)ensures excellent noise immunity,preserving high-speed encoder signals(up to 10 Mbps)even in electrically noisy environments with VFDs and welders nearby.

Innovation Point 3:Conductors are precisely twisted and paired to minimize crosstalk between power and feedback circuits,maintaining signal fidelity critical for high-resolution position control inΣ-7 systems.

Innovation Point 4:Factory-molded strain relief boots at both ends prevent wire fatigue and conductor breakage due to repeated flexing—extending service life in moving applications.

Innovation Point 5:As a genuine Yaskawa cable,the CACR-SR07BE12M is fully matched to the impedance and timing requirements of Sigma-7 drives and motors,avoiding compatibility issues seen with third-party cables.

Application Cases and Industry Value

At a pharmaceutical blister-packing line in Switzerland,a filling station used a high-speed Delta robot with Yaskawa Sigma-7 servos.After 18 months,the original servo cable failed due to fatigue in the wrist axis.The maintenance team installed the CACR-SR07BE12M as a replacement.Its flex-rated construction and right-angle termination allowed smooth movement through the cable carrier.Over the next two years,MTBF(Mean Time Between Failures)increased from 14 to 36 months.The plant engineer said,“We stopped treating servo cables as consumables.”

In a precision grinding machine,electromagnetic interference caused occasional positioning drift.Switching to the shielded CACR-SR07BE12M eliminated the issue.The ground continuity and low-noise design ensured±0.001mm repeatability.The CACR-SR07BE12M proved that the cable is not just a passive component—it’s part of the control loop.
