The Bosch Rexroth R911203233 (RD51.1-5B-018-L-CF-FW) model, manufactured by Rexroth Indramat, is designed to control servo motor movement through frequency conversion. This drive converter can transform fixed frequency current into variable current, thereby managing machine operation. Offering an 18 kW rated output, the converter operates with a 500 V nominal voltage (with a tolerance of ±10%). Key features include an integrated brake chopper linked to a brake resistor to enhance system braking power, electromagnetic compatibility, and line reactors for suppressing radio interference filters. For protection, the model has an IP20 rating, preventing the entry of particles larger than 12.5mm. The module should be installed in a control cabinet with a minimum IP54 rating and elevation below 1000m sea level. Provided with a one-year warranty from Indramat USA, this unit should be used alongside supplier-specified products for optimal performance. Ventilation gaps are necessary for forced air cooling. Firmware must be ordered separately.
