Product Description:
The BLIV-D100A servo drive is manufactured by Okuma and belongs to the BL Servo Drives series. Designed for machine-tool environments, it governs one motor by converting commanded position data into regulated current and voltage pulses. The unit fits CNC lathes, mills, and grinders where precise axis control is required for cutting accuracy. Inside an automation cell, it bridges the motion loop between the host OSP control and the power stage so that commanded profiles are executed without step loss or overshoot.
The drive uses a single-axis topology, which keeps wiring simple on compact machines. Current capability is selectable in five steps of 15/30/50/75/100 A, allowing one hardware model to match motors of different frame sizes. These settings are chosen with the SW2 DIP pack, which reads OFF/OFF/ON/OFF at 100 A and OFF/OFF/OFF/OFF at 15 A, while SW1 remains OFF/OFF as the default control mode. Cabinet layout is eased by a height of 197 mm, a width of 107 mm, and four 4-M6 mounting holes that align with standard panel grids. Despite the integrated power stage, the housing weighs only 6 kg, which helps keep handling manageable during installation.
The analog feedback ports provide process information. The torque monitor outputs 10 V per torque limit, so external recorders can verify load levels, and the velocity monitor supplies ±10 V at ±3750 rpm for speed observation or alarm logic. Internally, the power channel uses a control PC board and power unit architecture, separating signal circuits from high-current devices. Compatibility with OSP5020/OSP7000 controllers enables plug-in use on legacy or newer Okuma machines. With an overall length of 482 mm, the enclosure reserves space for the XB-DBR terminal, which is connected when the capacity exceeds 30 A and disconnected at 15 A to route braking energy safely.
