The Bosch Rexroth R911203126 (RD51.1-4B-045-L-DF-FW) drive control, an integral part of a three-phase drive system, is equipped with U/f control characteristics. It incorporates a line reactor and radio interference suppression filters within its design. Protective clothing must be worn and appropriate equipment used when handling this unit, with all maintenance work done after disconnecting from the mains power. The unit is often included in packaging, handling and foodstuff machines but it should not be used where there are high-temperature extremes or fluctuations. Designed for use with a motor and drive from the same manufacturer, the drive control relies on an external 24V standby power supply. Additional sensors and actuators may be required for motor control and monitoring. Manufacturer's cables are needed for device connection. The controller offers 3 x 380 to 480VAC nominal connection voltage with a 70kVA peak power for a minute and an output frequency from 0 to 250V. It can operate both with and without an EMC filter, offering an IP 20 protection level.
