Product Description:

The BL4-D7575A is a dual-axis servo motor module manufactured by Okuma for the BL Servo Motors series. It supplies precise torque and speed commands to CNC slides, loaders, and other automated stations, allowing two mechanical axes to be driven from a single, compact housing suitable for high-response, closed-loop industrial motion systems. Its rectangular body also simplifies stacking with additional axes on multi-motor frames.

The module supports an Axis Count of 2, enabling simultaneous positioning with one assembly. Each channel withstands a continuous Dual-axis Capacity of 75/75 A, covering rapid acceleration on heavy loads. Via software, users can select 15/30/50/75 A current levels for lighter machinery, a range noted as the selectable capacities. Control wiring relies on a Torque Cmd Scale of 10 V/(Torque Limit), translating a 0-to-10 V input directly to the programmed torque ceiling, while speed references follow a Velocity Cmd Scale of ±10 V/±3750 min⁻¹. Physical dimensions aid cabinet layout: the base height is 45 mm, body height 152 mm, body length 466 mm, and mounting width 80 mm; four M6 holes spaced along a mounting length of 450 mm secure the frame to the machine bed.

At 7 kg, the assembly is light enough for single-person handling yet heavy enough to resist vibration. Its outer profile is set by an Overall Height of 197 mm and an Overall Length of 482 mm, with an overall width of 160 mm so it fits standard electrical enclosures. A Top Plate Width of 144 mm accommodates cable trays or covers without exceeding the mounting footprint, giving designers clear allowances when positioning the motor near guides, sensors, or coolant ducts.
