Product Description:

For robotic and machine tool applications, the Bosch Rexroth Indramat KDA 2.1-100-3-DY0-U1 is a servo spindle drive from the KDA family that provides superior control and reliability.

This type, which has a cabinet-mount design and a nominal current rating of 100 A, can reliably drive high-power spindles. The unit works with both input and output voltages of 3 x 230/400 volts AC, making it compatible with industrial systems. When powering several kinds of rigorous working circumstances for dependable performance, it furthermore offers a constant current bus voltage of 300 volts for strong immunity. The heatsink blower is run by a 115 V AC source, and cooling is accomplished via an internal fan system. This effective thermal management solution can prevent the drive from overheating, enabling long service life when constantly operating under heavy-duty conditions. The KDA 2.1-100-3-DY0-U1 has digital servo feedback, which allows careful monitoring and control of spindle speed and position.

Both analog and digital control may be interlinked to give control, and a 16-bit parallel digital input is used to offer high-resolution control for speed control. The drive weighs about 7 kg, is compact and relatively light in terms of its performance class, and is simple to incorporate into control cabinets whilst not requiring excessive space or structural support. Installing the unit in a protected industrial environment, where it is shielded from large solid objects and accidental touch, is the goal of its IP20 protection class. It does not incorporate fieldbus communication as a typical feature and instead concentrates on direct analog/digital interfacing to integrate control. It can be purchased at Wake Industrial with a one-year warranty.
