Product Description:

The BLIV-D200A is a servo drive produced by Okuma within the BL Servo Drives series. As a single-axis controller, it regulates current and voltage to an attached brushless motor so that speed and torque follow commands from a CNC or PLC. The drive manages electrical output so the motor can respond steadily to commanded acceleration and changing load conditions during operation. In automated machine tools, it converts analog reference signals into precise motor motion and supplies pulse current suited to rapid positioning and cutting moves.

The enclosure stands 197 mm tall and 160 mm wide, while the body measures 152 mm in height and 466 mm in length for cabinet placement. Shipping mass is 8 kg, and the BLIV-D200A can supply up to 200 A of phase current for demanding motion tasks. Its velocity command interface uses a scaling of ±10 V/±3750 rpm, so a full-scale analog reference drives the motor across its rated speed range. The overall depth is 482 mm, and internal wiring exits at the front edge to help keep cable routing direct. These dimensions also help determine spacing around the power section and cable entry area inside the control cabinet.

The housing mounts on a 450 mm pitch with four 4-M6 threaded inserts, allowing direct fastening to a steel backplate without adapter brackets. Torque demand is handled through a separate analog channel scaled at 10 V/(Torque Limit), so speed command and torque limiting can be managed independently. Separating the torque-limit input from the speed reference allows the control system to cap motor load during demanding moves without changing the main velocity command. The drive controls a 1-axis loop, which suits applications that use one dedicated servo channel rather than a multi-axis rack. This arrangement supports straightforward panel integration where mounting access and short analog signal paths are important.
