Product Description:
The KDA 2.1-100-3-LY0-U1 Spindle Drive delivers efficient spindle control for automated machines. It is designed by Bosch to meet stable and accurate motion and positioning demands in different industrial automation setups.
The KDA 2.1-100-3-LY0-U1 drive operates using a DC voltage input. It works on a 300 V level through a power bus rail. Power rail design eliminates the need for external power routing. The design supports clean power distribution throughout the system. It does not include an auxiliary communication interface. Encoder input supports both auxiliary and synchronous feedback signals. This configuration improves speed and position accuracy in spindle tasks. Encoder flexibility improves compatibility across different motor types and applications. A dedicated heatsink blower is included for cooling purposes. This component maintains safe temperatures during high-speed or extended operation. The spindle drive is also conformed with C-axis functionality. C-axis support enables additional control over rotational positioning. This makes the unit suitable for complex motion systems. Built-in positioning attributes allow accurate command execution in real-time applications. These attributes increase system responsiveness in multi-axis machine tools. It maintains high stiffness for structural consistency under heavy loads. That stiffness helps to minimize vibration and reduce backlash during fast direction changes. The control attributes support stable motion tracking across programmed tasks. Voltage and signal processing remain stable under demanding conditions. It is compact and fits well in standard automation cabinets.
The KDA 2.1-100-3-LY0-U1 spindle drive supports spindle systems that needs position accuracy. Cooling airflow allows uninterrupted performance in temperature-sensitive environments. System integration is streamlined due to simple mounting and connection paths. This drive is ideal for operations that requires C-axis motion. It is built to handle advanced feedback control while maintaining structural stability. The drive delivers constant power and accurate thermal handling in automated lines.
Frequently Asked Questions about KDA 2.1-100-3-LY0-U1:
Q: What could be done if the KDA 2.1-100-3-LY0-U1 loses encoder signal during operation?
A: Inspect encoder wiring for loosened connections or signal interference, and recalibrate the feedback system to restore accurate spindle positioning.
Q: How does its built-in C-axis capability compare to drives without this function?
A: It enables advanced rotational control, allowing combined milling and turning operations, whereas non–C-axis drives are limited to standard spindle rotation.
Q: Why is the 300 V DC bus rail design beneficial in multi-drive setups?
A: It allows multiple drives to share a single, stable power source, reducing cabling complexity and improving overall system efficiency.
Q: How does dual encoder compatibility enhance spindle control accuracy?
A: Supporting both auxiliary and synchronous feedback ensures precise speed and position tracking, even in high-speed or load-variable conditions.
Q: In what way does the KDA 2.1-100-3-LY0-U1’s high stiffness improve machining quality?
A: it minimizes deflection under heavy loads, resulting in smoother surface finishes and reduced tool wear during precision operations.
