Product Description:
The MIV06DB-1-B5 inverter unit is produced by Okuma and belongs to the MIV Servo Drives series. Designed for CNC and general automation, this drive forms the power interface between the control cabinet’s DC link and one controlled axis. It modulates current according to resolver feedback so that BL or PREX servo motors follow commanded position, velocity, and torque profiles. With built-in monitoring and dedicated connection points, it integrates into multi-axis machines while maintaining consolidated thermal and wiring layouts.
The drive participates in a servo system that can supervise 8 axes, although it directly governs control axis 1. Its internal bus draws energy from a stable 300 VDC link, and the logic circuits are powered by a separate 24 VDC rail so field control remains active during a loss of line power. On the L side, the inverter can deliver up to 6.0 kW (8 hp) of mechanical output, providing capacity for medium-frame axes. Cabinet space is preserved by the unit’s 100 mm width, while its depth and height are 325 mm and 380 mm. The installed ICB1 board handles modulation, speed monitoring, and protective logic while maintaining a voltage error ratio of 1/42.
The feedback path relies on a resolver excited at 7.81 kHz that returns a 6.0 Vpp differential signal. This frequency and voltage pair supports fine angle interpolation without requiring excessive noise filtering. The analog speed monitor output is scaled at 1562 rpm/V and has a linear range of ±3 V, allowing external recorders to track axis velocity in real time. For torque supervision, the monitor port is clamped at 3 V at full scale, mirroring the drive’s internal current model. Synchronous communication between multiple inverters is handled over a loop cable up to 100 m long, while dedicated unit-to-unit links may extend up to 25 m when drives are installed on a common DC bus.
