Product Description:

The servo drive MIV0204-1-B3 produced by Okuma serves as an interpretive and regulatory system that connects controllers to motors to achieve precise machine movement. Okuma develops product solutions that are useful in multiple industrial automation challenges.

The MIV0204-1-B3 servo drive serves as an electrical unit that operates within MIV inverter systems for automated machinery axis control. The AC servo design handles power distribution to servo motors that operate in the designated L-axis and M-axis sections. Its system features two power-bearing axes that reach a power capacity maximum of 2.0 kilo Watts by supporting medium-scale industrial applications requiring precise motor coordination. At a small weight of 7.79 kilograms, its system allows an unmodified cabinet installation that does not require heavy force for support. Inside the drive, there exists an Inverter Control Board of type ICB1. The control board executes all switching along with modulation operations that allow driving through proper frequency and voltage signals. The board controls smooth movement and helps regulate speed and torque levels under different load circumstances. Users can integrate this system into multi-axis systems with its linkage to other machines and motion controllers.

The MIV0204-1-B3 servo drive contains a Control ROM which is mainly classified as Type 3 to store firmware and parameter data needed for core control logic operation. The ROM contains programmed instructions that enable consistent motor control functions so the unit has an upgradable or replaceable system during maintenance work or compatibility requirements. A Control ROM Type 3 configures this drive to handle essential performance features for day-to-day industrial environments which aids in making it suitable for machine tools and packaging lines or robotic systems.
