Product Description:
The KDA 2.1-100-3-LQD-U1 Spindle Drive is designed for applications that requires accuracy and control. It is developed by Bosch to provides effective performance in motor-driven machining systems and automation environments.
The KDA 2.1-100-3-LQD-U1 drive processes digital position command values with a resolution of 16 bits. It transmits data through a parallel communication mode to provides fast response times. This setup supports accurate speed regulation during critical movement phases. Speed control accuracy reaches down to 0.0005 rpm. Such precision makes the drive ideal for assemblies that requires ultra-fine motion regulation. It is built with high structural stiffness to minimize vibration. High stiffness provides better motion consistency during sudden directional changes. Its vertical rectangular design allows efficient use of cabinet space. This tall and narrow format fits well in multi-unit rack assemblies. It includes top-mounted cooling vents with wide slotted grills. The Bosch spindle drive enables digital input control and speed precision. The innovative and advanced design supports integration in small, high-demand cabinet-based environments. These vents allow continuous airflow to stabilize internal temperature. An integrated heat sink supports passive thermal dissipation during full operation. Together, these cooling attributes maintain performance under long-duty cycles. The drive is configured as a standard KDA spindle unit. It supports spindle-based motion systems in production or CNC setups.
The KDA 2.1-100-3-LQD-U1 spindle drive provides high-performance control in motion systems. Internal architecture is optimized for digital control commands. The combination of high resolution and accurate feedback increases motor coordination. Its casing design supports direct installation into drive panels. The enclosure prevents heat buildup while operating at peak power. All connectors and ports are positioned for convenient access during service. This helps reduce downtime during installation or maintenance.
Frequently Asked Questions about KDA 2.1-100-3-LQD-U1:
Q: How does the parallel communication mode improve drive responsiveness?
A: It transmits all bits of data simultaneously, minimizing latency and ensuring immediate execution of position or speed commands.
Q: What steps should be taken if the KDA 2.1-100-3-LQD-U1 shows irregular speed control during operation?
A: Verify encoder signal quality, inspect parallel communication cabling for damage, and recalibrate the drive’s speed control parameters through the system interface.
Q: What role do the top-mounted cooling vents and heat sink play in performance?
A: They promote continuous heat dissipation, preventing thermal buildup and maintaining stable drive operation during extended high-load tasks.
Q: How does the 0.0005 rpm speed accuracy benefit specialized machining processes?
A: It enables ultra-precise spindle control for operations like micro-drilling or fine surface finishing, where even minor speed variations can affect quality.
Q: How should connectors and ports be cared for during routine servicing?
A: Disconnect power before cleaning, use non-conductive contact cleaner to remove oxidation, and ensure secure reattachment to prevent signal interruptions.
