The Okuma BLIV-D100A is a 1-axis brushless AC servo drive amplifier (maintenance/replacement unit) from the BLIV-D series, with configurable power unit capacity of 100 A (peak/current limit). It supports motors requiring 15 A, 30 A, 50 A, 75 A, or 100 A rated current via jumper/switch settings on the control board. Input: 3-phase AC 200–230 V; output: variable 3-phase AC for BL/PREX series motors. Features optical interface for OSP CNC systems, PWM vector control, and high-response servo loop. Forced-air cooled; robust for high-precision axis feed in Okuma CNC machine tools. [stock available]
