Product Description:
Bosch is a well-known company producing top-quality products for use in industrial automation systems. The KDA 3.1-150-3-APD-W1 Drive is one of their products for spindle operations. This model provides accurate control in continuous-duty applications.
The KDA 3.1-150-3-APD-W1 spindle drive belongs to the KDA 3.1 series of main spindle drives. It is built to handle high current applications up to 150 A. This current rating supports high-torque machining and precision positioning. The drive uses forced air cooling through an integrated heatsink blower system. The blower requires a 220V power supply operating at 50 to 60 Hz. This active cooling design prevents overheating in continuous production lines. The drive receives speed command values through an analog +/-10V input. This enables accurate control of spindle rotational speed. It also has a digital interface for position command input. The digital input works on a 16-bit parallel signal format. These attributes support fast feedback and real-time motion adjustment. The device includes an auxiliary encoder input for added feedback. It allows connection of feedback from the spindle or a second motor. This increases synchronization in dual-motor systems and closed-loop control. The drive is part of the third series of KDA products. It is engineered for advanced system compatibility and reduced installation complexity.
The KDA 3.1-150-3-APD-W1 drive supports current handling and responsive signal integration. It enables smooth control through both analog and digital input sources. The drive suits demanding spindle and multi-motor control systems. It delivers efficiency and longevity in automated processes. Its electrical layout is designed to minimize latency in control communication and integrates easily into multi-axis systems and CNC machinery. Its structure is suitable for challenging industrial applications in production environments. Every detail in this unit supports long-term accuracy and system uptime.
