The Okuma BLII-D5050A is a 2-axis brushless AC servo drive amplifier from the BLII-D series (3rd generation), with power unit capacity 50 A per axis (first axis 50 A / second axis 50 A peak/current limit). Compatible with BL/PREX series motors requiring up to 50 A rated current. Input: 3-phase AC 200–220 V; output: variable 3-phase AC for precise multi-axis control. Features optical interface for OSP700/7000 CNC systems, PWM vector control, and high-response servo loop. Forced-air cooled; robust for high-precision feed in Okuma CNC machine tools.
