MIV04-3-V5
The Okuma MIV04-3-V5 servo drive, part of the MIV Servo Drives series, is a precision drive module engineered for advanced CNC machine control in industrial automation. Designed to optimize variable-AC motor performance, it operates on a 200 – 230 V AC three-phase input and delivers a continuous 1.1 kW output power at a rated 50/60 Hz frequency. Compact yet robust, the unit measures 380 × 60 × 325 mm and supports a speed control voltage of ±3 V, achieving a high resolution motor speed range of 1562 min⁻¹/V. This combination of power density and precise speed modulation makes the MIV04-3-V5 ideal for demanding machining applications where reliable, smooth motion control is critical.
Delving into the technical specifications, the MIV04-3-V5 integrates dual DC bus supplies (300 VDC and 24 VDC) to ensure stable power delivery. Its encoder interfaces accommodate A/B-phase signals at 2.6 – 4.6 V and a Z-phase signal exceeding 1.4 V (Vz1) or 0.5 V (Vz2). For resolver feedback, it supports a 7.81 kHz frequency at a typical 6.0 V p-p signal, enabling precise rotor position detection. A 7-segment LED display provides real-time status and error reporting, while torque output and voltage error signals use ±3 V ranges with a 1/42 scaling factor on d- and q-axes. Such comprehensive diagnostic feedback sets this drive apart by simplifying troubleshooting and ensuring continuous uptime.
Additional features of the MIV04-3-V5 include a built-in heat sink and forced-air cooling system to maintain optimal operating temperatures, extending component lifespan and reducing maintenance. Weighing 5.7 kg, the compact form factor allows flexible mounting on DIN rails or within CNC cabinets. The drive’s modular communication links—Servo Link for motion commands, Encoder Link for position feedback, and Converter Link for power regulation—ensure seamless integration with Okuma CNC controllers and third-party automation platforms. By meeting rigorous industrial performance demands, the MIV04-3-V5 enhances machine efficiency, stability, and productivity in high-precision manufacturing environments.
