Product Description:
The E4809-770-069-A is a control board produced by Okuma for the E4809 CNC Boards series. It is installed in machine-tool controllers to execute axis commands, supervise speed feedback, and trigger protective interlocks during automated cutting cycles. By coordinating with the servo drive and higher-level CNC software, the board helps maintain commanded feed rates and torque limits on a single mechanical axis. Its role links command processing with drive supervision so that motion responses stay synchronized during cutting moves, feed changes, and fault handling.
This model is classified as a 1-axis control board, meaning its logic and monitoring circuits are dedicated to one drive channel. Motor power is routed through a 3-phase main circuit that accepts 200 V AC. For field diagnostics, the board uses four test posts labeled VEL1, TO1, +5, and COM to mirror internal signals. A nine-element status bar uses green, yellow, and red lamps for immediate fault coding, and a single reset tact switch allows manual recovery. This arrangement lets operators check channel status and observe signal behavior from accessible points on the board. Real-time motion data are issued on two analog ports: a speed monitor delivers ±10 V / ±3750 rpm, and a torque monitor provides a 10 V / Torque Limit output so a drive or PLC can observe load conditions without additional sensors.
The logic section runs from a single-phase control supply and is rated at 100 V AC, and an auxiliary +5 V test output is available for signal reference during testing. The board can operate in plant atmospheres up to 75% RH and can tolerate short periods at 95% RH without dielectric breakdown. The assembly is rated for vibration levels of 0.5 G, which suits cabinet installations near heavy spindle drives. One control phase isolates low-level circuitry from the power stage, and the onboard +5 V line simplifies verification of encoder or sensor rails. These provisions keep low-level signal checks separate from the higher-energy motor circuit during routine electrical checks.
