Product Description:

The E4809-770-069-B is a control board manufactured by Okuma for the E4809 CNC Boards series. Installed inside numerical control racks, this printed-circuit assembly routes motion commands and feedback signals between the main processor and servo amplifiers. By handling timing and interlocks for a single motion channel, it supports precise table or tool movement in machining centers that rely on electronic automation. This arrangement helps the CNC keep acceleration, deceleration, and stopping responses consistent during automated machining cycles.

The board manages a single-axis configuration, so every input capture and command stream on the card is dedicated to one drive group. The Type A designation matches the signal layout used with current OSP controllers. Physical dimensions are 320 mm in length, 120 mm in width, and 40 mm in height, allowing the card to fit beside neighboring modules without obstructing adjacent slots. With a mass of 1.00 kg, the assembly adds little load to the rack while remaining stable in a vibrating cabinet. Five plug headers—XB6B, XB5B, XB2, XB3-1, and XB1-1—accept ribbon or discrete harnesses, and check terminals marked VELT, T01, +5, and COM provide accessible points for direct voltage checks.

Operational feedback is concentrated in a three-color LED group that uses green for run, yellow for reset, and red for malfunction to show the board state at a glance. A dedicated reset switch on the board edge permits local fault clearing without shutting down the entire controller. Additional coded lamps marked PON, OP, OCM, OCS, OV, UV, ROH/BOH, LOSS separate power, current, and communication conditions so the source of a fault can be narrowed to the drive, supply, or fiber link. The test points and indicators support straightforward status checks at the cabinet. Because the board has no special setting jumpers, it can be installed in the rack without manual jumper changes.
