​​Technical Principles and Innovative Values​​

The​​Yaskawa 3HNM07686-​​incorporates state-of-the-art technologies that deliver superior performance and ease of use.

​​Innovation Point 1:Vibration Suppression Control 2(VSC2):​​This advanced algorithm actively suppresses mechanical vibration at the machine tip.This allows for significantly higher servo gains,resulting in faster settling times and improved positioning accuracy,which is critical for applications like robotic arms and precision gantries.

​​Innovation Point 2:Adaptive Filter II:​​The drive automatically identifies and compensates for machine resonance frequencies.This”set-and-forget”feature simplifies tuning,reduces commissioning time,and optimizes performance without requiring expert manual intervention.

​​Innovation Point 3:High-Resolution Current Detection:​​With a high-speed 32-bit DSP and precise current control,the​​3HNM07686-​​provides extremely smooth rotation even at very low speeds,eliminating cogging and ensuring consistent torque output for applications like precision dispensing or grinding.

​​Innovation Point 4:Advanced Autotuning:​​The drive features robust autotuning capabilities that automatically adjust control gains based on the connected motor and load inertia.This ensures optimal performance from the start and maintains it even if load conditions change slightly.

​​Application Cases and Industry Value​​

​​Case 1:Semiconductor Manufacturing Handler:​​A manufacturer of semiconductor test handlers needed to improve the positioning speed and accuracy of the robotic arm that places chips onto test sockets.The existing system suffered from vibration-induced settling delays.By upgrading to a motion system centered on the​​Yaskawa 3HNM07686-​​drive and a matched Sigma-7 servo motor,the cycle time was reduced by 15%.The improved accuracy also minimized misinsertions,boosting overall equipment effectiveness(OEE)and reducing costly downtime.

​​Case 2:Metal Stamping Press Feeder:​​In an automated metal stamping line,a precision feeder was required to advance metal coils with micron-level accuracy at high speeds.The​​3HNM07686-​​was implemented for its excellent speed-torque characteristics and rigid control.The result was a dramatic reduction in feed errors,leading to higher quality stamped parts,less material scrap,and the ability to run the press at its maximum rated speed safely.
