Product Description:

The RZR01.1-RD52-0880-S-M-FW/S128 frequency converter is produced by Bosch Rexroth Indramat and belongs to the RZR Frequency Converters series. It serves as a motor inverter that translates low-voltage DC from the control cabinet into controlled AC output for precise speed and torque regulation on production machinery. Mounted inside an electrical enclosure, the unit works with drive controllers and feedback devices to support closed-loop motion on automated lines. This arrangement allows the converter to respond to changing load demands while maintaining stable motor behavior during routine machine operation. Because it is intended for enclosure mounting, surrounding system components can be arranged nearby with short internal cable runs.

Electrical operation uses a regulated supply of 24 V ± 5%, which powers the internal logic and cooling interfaces. The power section relies on single converter circuitry, so one channel handles the output stage and keeps cabinet wiring straightforward. Vector regulation is executed through field-oriented vector control, which separately manages torque-producing and flux-producing currents for fast response. During acceleration peaks, the converter can deliver up to 880 A to the motor, while the auxiliary supply draws only 12 A during steady operation. The IP20 housing helps protect against accidental contact with live parts while still allowing airflow inside a protected enclosure.

Continuous operation is permitted in ambient temperatures from 0 – 40 °C, so the cabinet environment must stay within that range during use. With a mass of 6.5 kg, the converter can be mounted on standard DIN rails or backplates without special handling equipment. Compliance with 3K3 (DIN IEC 721-3-3) indicates suitability for indoor areas with moderate dust and low humidity, provided the unit is kept away from corrosive vapors. The mounting surface should remain stable so the enclosure stays properly supported during operation. Indoor cabinets with managed temperature and limited airborne contamination are the intended installation environment.
