Product Description:

The E4809-045-110-C is a printed-circuit assembly manufactured by Okuma as part of the E4809 series of CNC boards. Serving as an ancillary motion module, the board plugs into the servo control rack to extend the number of controllable axes inside a machining center or turning cell. Its function is to supply the real-time position commands and feedback pathways required by drive amplifiers, thereby integrating additional mechanical movement into an existing industrial automation system without altering the main controller hardware.

The board is an SPC1 Card, and this designation matches the connector pitch and signal timing required for synchronization with the rack's servo bus. It is also identified as an Axis Card, indicating that it transmits interpolation data, drive enables, and alarm returns for a single servo loop. The added capacity is limited to 1 axis, which prevents channel overlap while keeping interrupt latency low. The card can be installed on the SVP-IID motherboard, and up to 3 such cards can coexist on one SVP-IID chassis, allowing incremental growth from one to four axes without replacing the underlying rack.

It is intended exclusively for machine tools managed by the OSP 5000 Series control family, ensuring compatibility with the card's handshake routines. For each new channel, the board presents a dedicated position encoder interface so incremental or absolute feedback reaches the servo loop at the correct resolution. A separate sensor interface carries limit switch, home, and over-travel signals, letting the motion channel complete reference and safety checks without using auxiliary I/O cards. By using the mechanical outline of the E4809 CNC Boards, the module keeps overall cabinet depth constant and helps maintain service access when additional motion capacity is required.
