Yaskawa’s high-end Sigma series AC servo systems have proven themselves for decades in such diverse applications as packaging machines, semiconductor manufacturing, timber processing or digital printing machines. And with Sigma-X as the latest evolution in the series, Yaskawa is once again setting new standards in performance and ease of use.
The very compact servo motors allows for the design of ever smaller machines. At the same time, the versatile tuning functions can be learned and applied very easily. Mechanically induced vibrations and resonances in the machine body are automatically detected and counteracted by the system. The acceleration sensors integrated in the new servo motors can now detect unwanted machine conditions at an early stage. In addition, the servo amplifier provides users with a variety of helpful information, such as electrical consumption, current power and temperature reserves, maintenance cycle indicators, vibrations, etc. This means that the performance of the machine is continuously monitored, analyzed and optimized in order to ensure maximum availability.
The system is currently available for 200 V with a power output of 50 W to 15 kW. Models for 400 V will follow in the near future. Servo amplifiers for the simultaneous connection of up to three servo motors are also now available, as well as models with special firmware for use in gantry systems. The available interfaces are Analog/Pulse and EtherCAT. All servo amplifiers are fitted with Safe Torque Off (STO) as a functional safety feature. An option card for additional safety functions plus FSoE (Safety over EtherCAT) will be available in early 2025.
