Product Description:
The E4809-045-039-B is a specialized axis control board from Okuma that functions by playing an important role in managing servo axis motion. Okuma solidifies its status as a cutting-edge machinery supplier that sustains its constant development with premium products.
The E4809-045-039-B circuit control board works by operating on a 24V DC supply and installs multiple key components to carry out real-time motion commands by making it essential for precision machine tool operations. It has been subdivided into a number of functional areas by incorporating a CPU section with the TDK CP-4606 microcontroller that drives the logic and control signals necessary to operate the axes. It is filled with the memory area that contains the EPROMs and perhaps RAM chips needed to hold firmware and run time variables important to the operation of the machine. The module is filled with ICs which probably would be used as signal buffers or digital isolators. Also includes standard TTL logic integrated circuits of 74LS series that helps in processing different low level control functions namely gating, latching and timing. There are also analog elements such as MC1458 op-amps and MC14053 multiplexers which support signal conditioning and D/A conversion.
The E4809-045-039-B control board uses PR2 and FEED-P features that correspond to programmable registers and feed pulse generation. The blue D-Sub connectors function for input/output communication with encoders and motor drives. The bottom-left corner houses a CP-6106 power regulation module for internal components. The DA2 and DA3 marked areas indicate digital-to-analog converter sections that generate analog voltage level from digital motion commands used to drive the servo amplifiers. The board is the well-engineered component that ensures accurate and efficient control in computerized machines.
