R911201400
The Bosch Rexroth Indramat R911201400 (RS51.1-4G-003-V-NN-FW) drive control is specifically designed for high-speed grinding spindles and forms part of their RS product range. With a rated output of 3kVA, it is primarily used in machine tool applications. Appropriate usage is critical due to the potential for elevated voltage and discharge current, hence only manufacturer-approved accessories and spare parts should be used. It must be ensured that the protective conductor is permanently connected to all electrical units as per the schematic before the power is connected.
The drive control is characterized by a U/f curve control and has a design code of 1. Its output frequency varies from 0Hz to 3,000Hz and should be disconnected from the electrical supply during maintenance, cleaning, and repairing activities. Parts of the unit are prone to electrostatic discharge and are capable of being damaged if improperly used. It features a removable operator panel with a copy function and complies with EMC guidelines for noise emission and noise immunity. It uses a nominal connecting voltage rating of 3 x 380VAC to 480VAC, and the input and output voltage, current and frequency ratings are found on the type plate. It weighs 20kg and the firmware must be purchased as a separate item. The unit, classified as size J, should be installed inside a control cabinet.
