RS51.1-4G-014-V-NN-FW

RS51.1-4G-014-V-NN-FW, Bosch Rexroth Indramat, RD 500 Drive Controllers The RS51.1-4G-014-V-NN-FW drive controller delivers precision motion control for high-speed grinding spindles within the RD 500 Drive Controllers family. Featuring a modular design, it integrates seamlessly into automation panels and offers smooth operation of synchronous and induction motors. The unit’s Device type as a drive controller for high-speed grinding spindles ensures reliable output under varying load conditions. The streamlined housing and straightforward mounting reduce installation time and optimize cabinet use.

This controller accepts a Nominal voltage of 3×380-480 V AC, 3-phase, and provides a continuous Rated power of 14 kVA with a Nominal current consumption of 19 A. For transient heavy-load scenarios, the drive sustains a Peak current of 29 A for up to 60 seconds, delivering a peak output of 18 kVA. Built-in Brake chopper and Resistor functions safely dissipate regenerative energy, supporting a Continuous braking power of 11.2 kW and a brake resistor value of 30 Ω. All electrical components reside in an IP20 enclosure sized to the standard K footprint.

Engineered for industrial uptime, the RS51.1-4G-014-V-NN-FW requires minimal air volume for cooling and includes an A1 radio interference suppression system for EMC compliance. With no need for additional functions, the controller’s plug-and-play architecture simplifies commissioning and parameterization. Backed by Bosch Rexroth Indramat’s global support network and a one-year replacement warranty, this RD 500 series unit delivers robust performance and sustained reliability in demanding production environments.
