Oriental Motor SG8030J Stepper Motor Controller

The SG8030J is a single-axis stepper motor controller from Oriental Motor’s Vexta line, engineered for standalone positioning and precise pulse control in industrial motion control systems. It accepts 24 VDC ±5% input, draws about 0.1 A, and supports up to 200 kHz oscillation frequency with a selectable 1-pulse or 2-pulse output. Operating modes include External Input (EXT), Program (PROG), and Test (TEST), with positioning options INDEX, HOME, SCAN, and TEST, and it can store up to four positioning steps, while photocoupler-isolated I/O supports noise resistance and PLC interfacing. The unit ships in a 48 × 48 mm DIN-size housing with a front-panel LED display and keypad, and mounting options for DIN rail (SG8030J-D) or panel (SG8030J-U); it is a replacement controller for Vexta stepping motor systems in industrial automation and motion control applications, with common replacements including SG8030S, SC8800, and AZ Series controllers, and it is a legacy/discontinued product.
