Feature-rich motor speed control

The Bosch Rexroth range of variable frequency drives provide a high-quality products that is easy to use and setup with a range of features that allow you to quickly programme your application’s exact AC electric motor speed control parameters.

With a detachable control interface that can be mounted on the forward door of the electrical control panel, users have simple and easy access to the unit’s potentiometer, stop/start control buttons and display screen. This means quick parameter settings access and optimising, intuitive diagnosis, and more other functions.

The detachability of the interface of these variable frequency drives allows operators to quickly configure multiple motor drives by copying and transferring parameters between each VFD using the panel’s memory and copy function in installations. This is also useful data processing and in the case of resorting the settings of an older VFD.

Additional braking resistors are available for applications where the controlled electric motor is required to stop instantly, dissipating the voltage produced via electromotive force.

interface, including Sercos, PROFINET, EtherCAT, EtherNet/IP and Modbus TCP.
