Product Description:
The KDA 2.1-100-3-L0D-W1 industrial unit is part of the KDA Spindle Drives product lineup, manufactured by Bosch Rexroth Indramat. Designed for CNC spindle operations, this model handles demanding machining tasks with a continuous current rating of 100 A, offering steady torque throughout production cycles. It operates at a rated voltage of 3 × 230/400 V AC, making it compatible with both European and international electrical grids.
With a frequency range of 50 Hertz to 60 Hertz, the gadget supports global power standards and ensures reliable operation across different regions. The device can easily connect with a three-phase mains supply, which supports more efficient power distribution and reduces electrical stress. For short bursts of high demand, the system delivers a peak current of 150 A, giving it the strength to absorb momentary overloads during torque spikes. A DC bus voltage of 300 V DC increases energy efficiency and keeps torque stable across different load conditions. The integrated SERCOS interface enables fast paced and real-time coordination between the drive and CNC controller, thus supports precise spindle performance.
The controller uses air cooling mechanism to manage internal temperatures, allowing it to stay thermally stable during extended operation. Its analog-controlled, field-oriented design supports fine torque control and fast dynamic adjustment improves spindle accuracy. This is a single-axis drive that simplifies setup in machines with a single spindle. The option to include a DC-bus choke or bleeder resistor adds adaptability for offering better control over voltage and electromagnetic interference. Resolver encoder for motor’s feedback maintains high positioning accuracy even under electrical noise, and keeps the spindle correctly aligned. IP10 protection rating limits access to live components, offering safer installation in controlled environments.
