MIV0104-1-B5
The Okuma MIV0104-1-B5 servo drive belongs to the MIV Servo Drives series and is engineered by Okuma to deliver precise dual-axis motion control. This compact unit weighs 7.8 kg and accommodates motor capacities from 1.8 kW to 4.0 kW on the L-side and up to 4.0 kW on the M-side. Its primary function is to regulate and synchronize two independent axes in CNC machines and industrial automation systems, ensuring responsive and coordinated motor operation.
In terms of technical specifications, the MIV0104-1-B5 features 2-axis control capability for simultaneous multi-axis coordination. The drive outputs a 6.0 Vpp resolver signal at 7.81 kHz for high-precision rotor position feedback. It also provides magnetic encoder signals for A-phase and B-phase at 2.6–4.6 Vpp (typ. 3.3 V) and Z-phase signals with Vz1 ≥1.4 V and Vz2 ≤0.5 V. Torque and voltage error monitoring are available via dedicated outputs: ±3 V torque monitor (3 V = peak torque) and ±3 V d-/q-axis voltage error monitors (×1/42 scaling), enabling real-time diagnostics and fine-tuning of control loops.
Beyond core performance, this drive integrates seamlessly with ICB1H-S and BL/PREX 1/2-axis control boards, enhancing system compatibility. Its external dimensions of 380×100×325 mm allow for straightforward installation in compact control cabinets, while the 7.8 kg mass supports robust mechanical stability and efficient thermal management. The inclusion of resolver and encoder interfaces ensures versatile feedback options across diverse motor types. In industrial applications, the MIV0104-1-B5 enhances process efficiency, reduces setup time, and maintains high-precision torque and speed regulation under variable load conditions.
