Product Description:
The Bosch Rexroth Indramat KDA 3.2-100-3-LYS-U1 Spindle Drive is also better in area of precision and versatility because it suits a large temperature range of operation as well as synchronized encoder input, sophisticated motion control as well as an AC powered cooling system that is eligible all over the globe. The module is highly suitable to perform stably in demanding environments while supporting advanced feedback configurations for high accuracy applications.
The KDA 3.2-100-3-LYS-U1 spindle drive is engineered to consistently operate with an electrical current capacity of 100 amperes which represents the maximum continuous current it can safely draw without thermal or electrical stress and ensures dependable performance. It uses an active airflow cooling with heatsink mounted fan which ensures thermal stability in that any heat that accumulates whilst operating is blown efficiently away thus protecting the working components and, in the process, extends the snapshots between working times. It is designed to work reliably within the F class humidity level as defined by the DIN 40 040 industrial standard which outlines specific moisture tolerance limits and ensures the remains stable even in environments with notable humidity. It includes an RS-232 C typical serial communication port as an auxiliary interface, mainly with uses in parameter setup, update of firmware and communication with other control systems or diagnostic tools via a computer or terminal.
This KDA 3.2-100-3-LYS-U1 spindle drive uses main power direct current bus backbone (that transforms and drives power to Spindle motor) and operates on 300 volts. It also limits the transmission of operational speed and control commands using SERCOS interface that allows it to be precise and in real-time nature in exchange of data between the spindle drive, CNC controllers and other automation devices. The cooling blower attached to it has a mass of 4.2 kgs which helps in planning for mechanical attachment, structural support and transport considerations.
Frequently Asked Questions about KDA 3.2-100-3-LYS-U1:
Q: Why does the KDA 3.2-100-3-LYS-U1 spindle drive use SERCOS for speed control?
A: SERCOS enables real-time, deterministic communication between drives and controllers. This ensures precise synchronization in multi-axis motion systems with minimal latency.
Q: How does the 100A rated current benefit spindle drive performance?
A: It allows the drive to support heavy-duty spindle loads without risk of thermal overload. This ensures stable torque delivery and consistent operational quality.
Q: Why is a 300V DC bus voltage used in the KDA 3.2-100-3-LYS-U1?
A: A 300V DC bus provides rapid energy transfer to the motor for dynamic response. This voltage level supports efficient speed and torque adjustments under varying loads.
Q: What’s the role of RS-232 C interface in this Bosch spindle drive?
A: The RS-232 C port enables configuration, diagnostics, and firmware updates. It's essential for initial setup and fine-tuning the system parameters.
Q: How does the forced-air cooling system improve drive longevity?
A: It actively removes excess heat, reducing thermal strain on internal electronics. This extends the operational life of the KDA 3.2-100-3-LYS-U1 under constant load conditions.
