■ Suppression of deviation with short response time The Yaskawa Power Lead Switch "Vesta Act" is built into the contact part, resulting in significantly shorter response times (reset time and operating time) compared to general relays. Reliable and fast switching enables instantaneous stopping of the motor during brake operation. It suppresses minor deviations such as drops, protecting the fixtures and workpieces of equipment in operation. ■ Contributing to stable operation of equipment with long lifespan The unique contact structure is less affected by external environments, preventing oxidation and corrosion of contacts that can cause contact failure. With a double contact structure that separates the magnetic contact part from the contact part, contact reliability is enhanced, achieving a low failure rate. Even with high-frequency use, the interruption time does not extend, and there is no increase in contact resistance. Glow discharge occurs during inductive load interruption, preventing wear on the contacts. * As of 2023, it has become the recommended relay. Please refer to the "Relay Page for Brake Opening and Closing" in Yaskawa Electric's latest catalog under "Connection with Servo Packs and Peripheral Equipment." You can also check the wiring and detailed specifications with servo packs/motors from the "Download Catalog" below.

- Solving the issues of short lifespan and contact failure in relays used in FA equipment control panels. - Reducing running costs of equipment and mitigating recent material procurement risks by decreasing replacement frequency. - FA market relays that leverage product technology required for long lifespan and high reliability, particularly in railways, power, and steel industries. ■ FA Equipment Case Study 1 It has been adopted for the opening and closing control of electromagnetic valves. Before adoption, a protective circuit was necessary to counter surge voltage when the electromagnetic valve was opened, and the electromagnetic valve would fail to operate due to contact failure in general relays. With the adoption of the Bestact relay, direct control of the opening and closing of the electromagnetic valve became possible without using a protective circuit. Additionally, contact failure has improved, leading to stable operation of the electromagnetic valve. ■ FA Equipment Case Study 2 It has been adopted for the switching relay of linear motors used for transporting vegetable bases in a vegetable factory. Before adoption, the relay was frequently opened and closed, requiring replacement every three months, and contact failure occurred due to the high humidity in the harsh environment. With the adoption of the Bestact relay, mechanical lifespan and contact failure have significantly improved. The replacement cycle has been greatly extended, leading to reduced maintenance costs.
