Bosch Rexrot REFU Drive 500 AC drives

Electric drives of the family RD 500 Bosch Rexroth is designed to control the operation of asynchronous and synchronous electric motors, including specialized ones. A large arsenal of application functions and pre-installed technological algorithms for ease of use, debugging of production processes and other intellectual capabilities with software for remote work using a computer. There is also a graphical interface on the front panel for direct launch. The flexible configuration of the modular architecture ensures the creation of the most suitable and practical version of the drive system for specific application conditions.

The compact series converters included in this family RD51 /RD52 presented in a wide variety of configurations, these are the most flexible and at the same time cost-effective solutions for multi-profile use. Ruler RS51 It was designed to work as part of high-speed applications, in particular for spindle installations with a rotation speed of up to 180,000 rpm.
