Product Description:

The E4809-045-109-F belongs to the E4809 CNC Boards series manufactured by Okuma and serves as the Master Axis Board inside an OSP controller rack. Classified as an SVP Board, it supervises motion commands, converts analog feedback, and coordinates drive signals so brushless servo motors can be positioned precisely during machining operations. By hosting both digital-to-analog and analog-to-digital converters, the board forms the central link between numerical control calculations and the power modules that energize each mechanical axis.

This SVP module governs up to 2 axes, issuing command voltages that swing across a full bipolar range of ±10 V while monitoring incoming feedback that is scaled against 10 V on the A/D side. One matched DA/AD set ensures synchronous sampling for both channels. Three major motion-related signals are distributed through the backplane, and the board exposes the field terminations on the front panel via CN-SV-3/CN-SV-4/CN-SI-3 sockets. Six discrete measurement points are available because the board provides 6 sensor inputs that can be mapped to temperature probes or limit switches. For manual jogging, there is a single pulse handle interface, and a separate pulse generator interface supplies incremental reference pulses, with each interface rated at one channel.

The axis feedback layer is organized around an Absolute Position Encoder format so the machine retains position after power cycles. Control outputs are optimized for Brushless Servo drives, and servo parameters follow the SVPIID code for compatibility with earlier SVP hardware. An SPC1 mezzanine slot accepts up to three daughter cards, allowing additional serial or I/O resources to be added without replacing the base board. Total mass is kept to 3.00 kg, which reduces enclosure load and simplifies removal during scheduled maintenance.
