Product Description:
The BLII-D7530A is a two-axis AC servo amplifier produced by Okuma as part of the BL Servo Drives series. It uses a dedicated SVCII Board for two-axis command processing, linking the CNC controller to a pair of servo motors through coordinated current control. By modulating stator current in real time, the amplifier supports stable speed regulation, smooth interpolation, and fast response during positioning moves in machining centers and material-handling equipment. This arrangement allows both axes to be managed from one drive package while maintaining coordinated motion behavior during demanding cycle changes.
Its first output channel can deliver up to 75 A of continuous motor current, while the second channel is limited to 30 A. The unit supports 2 axes, so both channels are supervised through a common control platform that handles feedback processing and command distribution. Low-level electronics are powered by a control circuit rated at 100 V AC, while the main power section draws from 200 V AC factory mains. Separating the control supply from the power stage helps protect command electronics from switching noise and keeps motion response stable during rapid load changes.
Control electronics operate from a 1-phase supply, while the inverter section is connected to a 3-phase source to support smoother power delivery under dynamic motor demand. If either motor exceeds the permitted instantaneous current, an overcurrent circuit trips at 150% of limit current, shutting off gate drive before the output devices are overstressed. For diagnostic integration, the drive provides a speed-monitor output of ±10 V that corresponds to motor speed, along with a separate torque-monitor channel at 10 V. The unit also permits installation on the machine frame where normal ambient humidity and moderate vibration are present, helping it fit enclosed industrial equipment without requiring a separate remote mounting location.
