Product Description:
The E4809-045-158-A is an Okuma OPUS7000 SVP Board that is specifically designed for CNC systems that necessitate precise servo drive processing. It is an SPV board that is responsible for real-time motion control, which guarantees precise axis movements and spindle operations.
The E4809-045-158-A SPV board, in contrast to the 68020 series, is equipped with two 16MHz Motorola MC68EC030RP16 processors, enhancing its capacity for real-time processing. To make sure the motion runs properly, these 32-bit microprocessors manage the system logic and servo calculations. Data transfer and buffering are both enhanced by memory integrated circuits that allow for real-time data storage, like SRAM or DRAM processors. To handle system connections and signal processing, the board makes use of logic ICs from the 74xx series. Connectivity is made easier with the P100830P-ITD20 backplane connections, which communicate with the motherboard of the CNC system. To facilitate the linking of servo gearboxes and motors, a number of high-density D-sub connectors from the XB-SVP series—XB-SVP-1 through XB-SVP-9—are utilized. More expansion opportunities arise from border connections as well. The efficient operation of power management is guaranteed by electrolytic capacitors, which control voltage and eliminate noise. The XTAL1 and XTAL2 crystal oscillators generate the clock signals that synchronize the processing of feedback with motor control.
The E4809-045-158-A board is equipped with a watchdog timer that guarantees the detection of faults during system operations. In order to prevent overheating and guarantee consistent performance, a thermal sensor monitors temperature levels. Due to the board's perfect motion control, the servo motors and machine movements never deviate from one another. By using specialized components, CNC systems provide maximum efficiency and accuracy. The board is essential for the maintenance of system stability, the improvement of response times, and the enhancement of overall machine precision.
