Product Description:

The Bosch Rexroth Indramat RD52.1-4B-160-R-V1-FW/S134 belongs to the RD 500 Drive Controllers series and functions as the regulating interface between a three-phase supply and high-power motors in automated cells. It serves as the control section of the platform and adjusts output frequency and voltage so conveyors, extruders, and test stands follow programmed speed or torque profiles during varying load conditions. Because regulation is handled in the drive, the connected motor can maintain smoother operation when process demand changes during production. This makes the unit suitable for applications that require stable speed control and repeatable torque response across long operating cycles.

The controller delivers a continuous output of 160 kW, which suits large production machinery that requires high shaft power. It accepts line voltages from 380 to 480 V, permitting direct connection to standard industrial networks within that range. A liquid-cooling system with an internal pump, used on frames rated at 132 kW and above, removes switching heat and helps limit temperature rise inside the cabinet. Drive dynamics are managed by field-oriented vector control, which supports precise current regulation and stable torque at low rotor speeds. An integrated mains filter suppresses conducted electromagnetic noise and reduces interference on nearby equipment.

Regenerative energy is dissipated through a built-in brake chopper, eliminating the need for separate braking hardware on fast-stopping axes. The power stage uses a three-phase AC converter input, and the supply can vary within a ±10 % tolerance on the specified voltage range without interrupting normal operation. For control electronics and fieldbus retention during mains loss, the unit draws 24 V standby power from an external source. This device is design generation 1 of the platform. That generation marking identifies the product version used for this drive type.
