MIV08A-3-V5

The MIV08A-3-V5 from Okuma is a high-performance drive in the MIV Servo Drives series, engineered to deliver precise control for industrial VAC motor systems. This inverter unit provides a rated continuous capacity of 7.5 kW (10 hp), ideal for moderate to heavy-duty applications that demand consistent power output. Compact in design, its external dimensions of 380 mm × 100 mm × 325 mm ensure seamless integration into control cabinets and machine frames with minimal space requirements. Weighing just 7.3 kg (16.1 lb), the drive balances portability and robustness, easing installation and maintenance processes. Constructed specifically as an Inverter Unit for VAC Motors, it supports broad compatibility with ICB3H, ICB3, or ICB3F control boards for versatile deployment across diverse automation platforms.

In its operational environment, the MIV08A-3-V5 draws from power source requirements of 300 VDC and 24 VDC, facilitating reliable performance under dual-voltage supply conditions. Its output voltage range of –3 V to +3 V and defined motor speed output unit of 1562 min⁻¹/V deliver fine-grained speed regulation and responsive torque control. The drive’s signal interfaces include a resolver signal output voltage of 6.0 V (typical) and magnetic encoder inputs with an A-phase signal voltage of 2.6 V to 4.6 V plus a Z-phase signal voltage of 1.4 V or higher, enabling high-resolution feedback for advanced motion loops. The control algorithm maintains motor voltage error (d-axis and q-axis components) within –3 V to +3 V with a multiplication factor of 1/42, ensuring tight current control and minimal torque ripple. Although the operational temperature range must be referenced in the official manual, the drive’s design supports continuous operation in industrial environments.

Reliability is reinforced through rugged construction and precision-engineered electronics that withstand the demands of industrial automation. The unit’s unit type for configuration MIV08-3 for VAC Motor Systems simplifies firmware setup and ensures compatibility with existing Okuma CNC and PLC platforms. Integration is further streamlined via standardized control board sockets supporting ICB3H, ICB3, or ICB3F modules, reducing installation time and potential wiring errors. The inverter’s proven performance in factory automation, robotics, and material handling systems underscores its adaptability to a wide range of applications. With Okuma’s commitment to quality and the MIV08A-3-V5’s comprehensive specification set, engineers can deploy a reliable, efficient drive solution for demanding VAC motor control tasks.
