Product Description:

The KDA 2.1-150-3-A00-U1 is a high-capacity and rugged drive. It is intended for inclusion in motor-driven systems needing superior torque control and current accuracy. It is a three-phase drive with a constant current capacity of 150 A, capable of meeting high-demand situations through the means of constant flow of controlled power provision to deliver maximum performance from attached motors.

The drive accepts a 300 V DC input voltage, sourced from a centralized DC bus for enhanced system-wide power efficiency and convenience of multi-axis configuration. With the capacity to support peak currents up to 1.5 times its rated output, short bursts of up to approximately 225A of current can be provided to respond to transient load demands, allowing for greater responsiveness under acceleration or heavy-duty operations. Made for compatibility with servo motors, this unit is used for direct integration with compatible hardware. It gives better motion and latest automation precision. Firmware qualified as A00 is synchronized with series version U1. This regulates its distinctive software architecture and functional compatibility within vintage and contemporary systems. Communication with the unit is facilitated via proprietary Indramat parallel and serial interfaces, allowing for configuration, diagnostics, and operating feedback through specialized software. Employing a current loop control structure in association with torque regulation, the KDA 2.1-150-3-A00-U1 ensures precise drive performance, adjusts motor behavior according to real-time demands, and ensures stable and efficient operation under varying loads.

Whether used in material handling, high-speed robotics, or process automation, its high-capacity current handling, intelligent design, and compatibility with established motor systems make it a reliable cornerstone for any performance-driven automation platform. The drive configuration is ideal for applications requiring reliability, precision, and long-term support in high-throughput industrial settings where control and power must work in harmony.
