Product Description:

Okuma made the VAC5-D8-AIF that a high-performance spindle drive for very precise motion control tasks. It combines different driving abilities into a single system, which makes sure that industrial automation works smoothly. The drive is built with a strong power module and control PCB that makes it more efficient and reliable.

The VAC5-D8-AIF spindle drive has important technology features that make it work better. Dedicated switches are used to set the current limit, which ensures precise working control. At FR = 5.0 A, the torque limit is set, and at FS = 5.0 A, the firmware write mode changes are made. The gain of the speed amplifier controls the motor control settings so that the performance stays stable. The drive has a power module built in that handles power input and delivery efficiently. The control PCB has real-time speed regulation and torque control that make the operation more stable. The switching mechanisms set constant limits on the current, which makes things safer and better at what they do. The structured design lets you fine-tune operational parameters using specialized switches that make customization easier. This spindle drive works better with robotic systems and is more efficient because it connects D6A to D8A and D6B to D8B.

The VAC5-D8-AIF spindle drive is 530 mm long and 200 mm wide, and it weighs 22 kg. The unit has an improved feedback system that makes data transmission more accurate. With its advanced thermal control system, the system will always work at a stable level. The structured design and combined parts make it reliable over time and flexible for high-performance uses. This spindle drive meets strict operational standards that make sure automated systems work well.
