Product Description:
The KDA 2.1-100-3-LQD-W1 Spindle Drive accommodates a 100-ampere rated current, which allows it to achieve efficient handling of high-demand spindle loads. Built by Bosch Rexroth Indramat, it is particularly designed to meet high-performance, precision-controlled motion systems.
At a 70 amperes sustained current rating, this spindle drive provides stable, continuous operation in load conditions with minimum risk of overheating during long-term runs. It runs at a DC bus voltage level of 300 volts and is thus compatible with standard industrial power supply arrangements for straightforward integration. This spindle drive features an integrated heatsink blower-powered forced air cooling system for optimal internal temperatures during high-speed cycle applications. The KDA 2.1-100-3-LQD-W1 drive is capable of sustaining up to 55 °C as its maximum operating temperature, which makes it suitable for use in warmer industrial environments. This drive is designed to operate between a temperature of +5 °C to +45 °C for effective performance within a wide range of conditioned indoor environments. Its position commands are processed by using a 16-bit parallel digital interface for enhanced data processing and high-resolution feedback.
The speed commands of the KDA 2.1-100-3-LQD-W1 spindle drive are communicated via a SERCOS interface. This interface enables high-speed and reliable digital communication, ideal for synchronized motion in multi-axis drive systems. This spindle drive features an auxiliary encoder input, which supports 1V sinusoidal encoder signals for improving feedback accuracy in closed-loop position and motion operations. The humidity resistance of this drive is provided through Class F by DIN40040, giving protection against moisture damage in applications with fluctuating humidity. The 1.7-kilogram weight of the bracket assembly allows this drive to be light enough for easy mounting, manipulation, and panel setup without heavy support frames.
