Product Description

The RD52.1-4N-011-L-V1-FW is an inverter-based RD52 series drive controller from Bosch Rexroth. The input voltage range of the drive inverter is 530 to 670 Volts DC. The allowed input voltage tolerance is ±10%. RD52 drives support the option of a brake chopper. The RD52.1-4N-011-L-V1-FW does not feature an integrated brake chopper. Nominal motor output of the RD52.1-4N-011-L-V1-FW drive is 11 kilowatts. The output power, current and other parameters vary with pulse frequency used during operation. Options for pulse frequency include 4 kilohertz and 8 kilohertz. Size class of the drive unit is B. The protection category of the housing is IP20. Bosch has designed the controller for forced air cooling. Compared to natural convection, forced air cooling allows the controller to operate at higher levels of power and current output.

The RD52.1-4N-011-L-V1-FW is a modular unit. Customers can customize it through selection of firmware and hardware options. The RD52.1-4N-011-L-V1-FW includes one hardware option that is 24 Volts standby power. This option gives operators a lot of flexibility: field buses can operate and the drive can be parameterized even when the DC input supply is non-connected. Applications of the drive controller include chemical and process technology, foodstuff machines, packing machines, conveyor technology and machine tools. The drive should only be operated under the specified mounting conditions and specified ambient conditions. The storage temperature range is -25 to 70 degrees Celsius. The environment used for storage should be clean and dry. Dust present in the operating environment can damage the controller. Therefore dust laden air should be filtered. The air in the operating environment should not contain aggressive or chemically conducting gases that can damage the working controller.
