Product Overview
VA series is a high performance synchronous and asynchronous AC servo driver developed for permanent magnet synchronous AC motor and three-phase asynchronous motor. VA series support RS485 communication and EtherCAT bus, and combine with the upper computer to have multiple servo drivers controlled with networking and field bus system.
