MIV-02-1-B5
The Okuma MIV-02-1-B5 servo drive is a high-performance member of the MIV Servo Drives series, engineered for precise motor control in demanding industrial automation environments. It delivers a rated continuous capacity of 2.8 kW (3.73 hp), providing robust and constant power for two-wheel motor setups. This device supports both BL motor and PREX motor control for versatile application across multi-axis systems. Housed in a compact enclosure measuring 380 × 100 × 325 mm, the drive weighs 7.8 kg, balancing power density and ease of integration. The MIV-02-1-B5 is designed with an emphasis on reliability, accuracy, and sustained thermal performance under continuous load.
Paragraph 2: The drive’s electrical interface features an output voltage range of –3 V to +3 V and a motor speed constant of 1562 min⁻¹/V, ensuring accurate speed regulation. Position and velocity feedback is managed via a magnetic encoder, with the A-phase signal Vpp specified at 2.6 to 4.6 V (nominal 3.3 V) and Z-phase signal voltages of Vz1 ≥ 1.4 V and Vz2 ≥ 0.5 V. Resolver inputs are supported with a monitor terminal resolver signal of Vpp 6.0 V at approximately 0.128 msec (7.81 kHz). Motor voltage error detection is provided at a monitor terminal multiplication factor of 1/42, allowing precise fault analysis. The internal display card with status indicator grants real-time system feedback, and the optional external fan (E1310-528-054) maintains thermal stability.
Paragraph 3: Operational performance in the MIV-02-1-B5 centers on consistent torque delivery and rapid response to control signals. Peak motor torque is attained at 3 V of drive output, facilitating high-acceleration tasks. The drive’s control board, a BL Motor 2-axis control board (Discontinued) type, supports coordinated multi-axis motion profiles and real-time parameter tuning. Ambient temperature resilience and durability are enhanced by the external cooling fan system, which reduces thermal drift and maintains junction temperatures under high load. System diagnostics use both voltage error monitoring and encoder signal verification to ensure continuous, safe operation without unexpected shutdowns.
Paragraph 4: Integration of the Okuma MIV-02-1-B5 servo drive is streamlined for CNC machines, robotic cells, and precision assembly lines, relying on standard industry interfaces and the proven BL/PREX motor family. Its compact form factor and weight of 7.8 kg simplify mechanical mounting and cabinet layout. The combination of advanced feedback monitoring, external cooling provisions, and robust power handling makes it ideal for machine tool spindles, high-precision gantry systems, and automated material handling applications in manufacturing facilities.
