Product Description

The RD52.1-7N-075-W-V1-FW/S122 is a RD52 series universal drive from Bosch Rexroth. It is designed for control of synchronous and induction motors from Bosch. The design of the drive is modular and allows the drive to be adapted to different applications. RD52 drives can be converter or inverter based. The modules of the drive can be ordered individually or as an assembled unit. The technical characteristics of RD52 drives include AC or DC supply, forced air or liquid cooling, graphical display, support for multiple communication interfaces and peer-to-peer coupling for fast communication between drives. The RD52.1-7N-075-W-V1-FW/S122 is rated for 75 kilowatts output and 170% output overload for 1 second. The type label that is attached to the drive lists essential drive specifications and should be checked at time of equipment deliver.

The information listed on the type label can also prove useful when replacements or accessories need to be ordered. The RD52.1-7N-075-W-V1-FW/S122 is an inerter-based drive. The drive inverter is rated for 530 to 670 Volts DC input. A brake chopper is not part of the drive inverter. The RD52.1-7N-075-W-V1-FW/S122 is a liquid cooled drive that requires 0 to 40 degrees Celsius ambient temperature. Bosch does permit drive operation between 40 and 50 degrees Celsius. However the output of the drive derates at a rate of 2.5% per K between 40 and 50 degrees Celsius. The rated operating power loss for the drive is 2.1 kilowatts. Size class of the drive is D and the protection category of the housing is IP20. Improved liquid protection requires drive mounting inside an industrial cabinet. Support for 24 Volts DC stand-by power is available. Only qualified technical staff should operate the RD52.1-7N-075-W-V1-FW/S122 drive. This product can be shipped globally with a one year warranty period from Wake Industrial.
