Product Description:
The Bosch Rexroth Indramat KDA 2.1-150-3-AQI-U1 Spindle Drive has an extensive speed capability and it adapts seamlessly to tasks that demand delicate low speed accuracy or high speed efficiency. Its incremental encoder output provides precise step by step feedback on movement.
The KDA 2.1-150-3-AQI-U1 spindle drive possesses a strong resistance to deformation under load and it can maintain its shape and stability even when subjected to external forces, vibrations or torque changes. It is engineered to safely handle an electrical current of 150 amperes during regular use which defines the continuous electrical strength it can manage without overheating. An auxiliary signal input is provided that accepts sinusoidal encoder feedback at a voltage level of 1 volt which allows it to receive high resolution positional data. It belongs to the 2nd release or product sequence in its line which often reflects improvements or adjustments over the initial design. Its primary purpose lies in accurately setting or relocating the spindle shaft to a specific point which means it is not only about rotation or power delivery. The cooling fan attached to the heatsink requires an AC input of 115 volts which ensures that the cooling system runs independently and provides the necessary air circulation.
This KDA series drive design number of 1 represents its layout, construction method and functional concept used in its development. Its speed can be instructed through an analog input that ranges between +10 volts and - 10 volts. The heat generated in this drive is carried away using a blower system that actively forces air across a heatsink. It is capable of sustaining the same power output across a wide range of speeds which ensures uniform performance at either lower or higher rotational rates.
Frequently Asked Questions about KDA 2.1-150-3-AQI-U1:
Q: How does the KDA 2.1-150-3-AQI-U1 maintain accuracy during both slow and fast spindle operations?
A: Its control system dynamically adjusts output to match varying speed requirements. This allows reliable fine machining at low RPMs and consistent efficiency at high RPMs.
Q: What role does the incremental encoder output play in this spindle drive?
A: The encoder delivers precise step-by-step motion data. This feedback helps maintain accurate spindle positioning and synchronization with other machine axes.
Q: How does the KDA 2.1-150-3-AQI-U1 ensure reliable operation under mechanical stress?
A: It features a robust construction that resists deformation under torque or vibration. This stability preserves machining accuracy and extends equipment lifespan.
Q: Why is a ±10V analog input significant for speed control?
A: The analog input provides flexible bidirectional speed commands. Operators can achieve smooth transitions between low and high spindle speeds.
Q: How does the auxiliary sinusoidal encoder input improve performance?
A: It accepts high-resolution feedback signals from the encoder. This allows tighter motion control and better accuracy in tasks like contour cutting or threading.
