Product Description:
The BLIV-D7575A is a servo drive designed and manufactured by Okuma within the BL Servo Drives series. As a dual-channel amplifier, it interfaces with machine controllers to regulate current and velocity loops for brushless servo motors used in automated machining centers and related equipment. By converting a three-phase AC supply into controlled outputs, the unit provides the closed-loop actuation required for positioning, contouring, and feed functions on CNC axes. It also works with Okuma OSP control architecture to support coordinated motion across the machine.
The drive supports 2 axes, allowing simultaneous control of a pair of servo motors from a single enclosure and reducing cabinet space. It communicates with OSP5020/OSP7000 control systems, so parameter data and alarms are exchanged directly over the native bus without external converters. Electrical compatibility is broad because the power section accepts an input frequency of 50/60 Hz, allowing operation in regions that use either mains standard. The power stage is built for a three-phase AC supply, which provides balanced line loading compared with single-phase input. Selectable current ratings of 15/30/50/75 A are available, allowing the drive to be matched to the connected motor and application duty while limiting unnecessary thermal stress.
The housing has an overall length of 482 mm, an overall width of 160 mm, and an overall height of 197 mm, which gives a clear footprint for cabinet layout and airflow planning. Four M6 mounting holes with 450 × 80 mm spacing align the unit on a backplane, while the mounting length of 466 mm and mounting width of 144 mm keep the fasteners inside the drive housing outline. With a mass of 7 kg, the unit remains compact while providing the rigid structure needed to support its internal power electronics. These dimensions also help maintain consistent placement alongside adjacent control hardware in machine cabinets.
