The LECY drivers are compatible with the MECHATROLINK open field network, operating AC servo motors with 20-bit absolute encoders. LECYM uses the MECHATROLINK-II protocol to connect up to 30 units at a max distance of 50m with 10 Mbps transmission speed. LECYU uses the MECHATROLINK-III protocol, connecting up to 62 units at a max distance of 75m between units, with 100 Mbps transmission speed
