Product Description:

The MIV04A-E Servo Drive is designed and developed by Okuma. This model offers high reliability and is suitable for various industrial automation settings. This unit is capable of controlling two axes when used together with BL motor series and is designed to generate 4 kW of rated power at motor’s output shaft. Through its design, this servo drive delivers exact motion control for various industrial requirements.

The MIV04A-E servo drive offers -3 V to +3 V of output voltage for precise speed control of the attached motor. The device controls speed precisely using 1562 min⁻¹/V as its motor speed unit. The drive must be operated under the specified environmental conditions. The feedback function relies on a resolver signal voltage of 6.0 V (typical) for accurate measurements. The MIV04A-E servo drive incorporates port specifications that amount to 380 × 100 × 325 mm (14.96 × 3.94 × 12.79 in). The device includes a mass of 7.8 kilograms (17.2 pounds) which allows simple installation within systems. This drive operates through external inputs ranging from 300 VDC up to 24 VDC. As a functionality component, this device offers inverter capabilities for spindle motors and axis drive motors simultaneously.

The MIV04A-E servo drive uses servo links for communication purposes while also using encoder links and converter links. Users benefit from better functionality when combining the drive with ICB1H-S control boards. The system includes fan cooling as an external method to dissipate heat effectively. The monitor terminal provides an output multiplication of 1/42 for voltage error signals to fulfill accurate diagnostics performance. This drive functions best for applications in CNC machines and industrial automation systems. It achieves both high operational precision and performs well in challenging applications.
