Product Description:
A strong spindle drive in the KDA family, the Bosch Rexroth Indramat KDA 2.1-150-3-DYD-U1 can precisely regulate an AC servo motor in a manufacturing environment.
The unit is a KDA 2.1 that can support three controlled axes and is made to work with multi-axis systems. Heavy-duty servo motors can be driven in dynamic load mode by it, since it can deliver up to 150 A of authorized current. Its control electronics are powered by a 24 V DC internal wetting voltage that powers its motor. Depending on the industrial power need, it will run on an AC three-phase input with a voltage range of 380 V to 480 V and compatibility with either 50 Hz or 60 Hz. The feedback system uses DYD technology and can manage position and speed accuracy in a wide variety of applications by using a resolver or encoder-type feedback device. The cooling process is handled by the internal air circulation, which makes the system design simpler to manage and eliminates the need for several external cooling systems.
Because of its IP20 protection rating, it may be mounted in control cabinets that are firmly sealed. Analog and digital interfaces that are widely integrated with both new and old control systems are used to conduct the communication. The weight for the panel-mounted drive is about 18 kg. Its dimensions—482 mm in height, 482 mm in width, and 235 mm in depth—allow it to fit into standard enclosures while yet having the capacity needed for applications in industries. It is completely compatible with Indramat AC servo motors and may easily run in the Rexroth motion control ecosystem.
