Product Description:

The RS51.1-4G-006-L-V1-FW basic drive is manufactured by Bosch Rexroth Indramat and belongs to the RD 500 Drive Controllers series. This three-phase converter regulates motor speed in automated machinery by adjusting output frequency and voltage, making it suitable for conveyor, pump, and material-handling tasks that rely on centrally located control cabinets.

The unit accepts a 380 – 480 V input from a Converter 3 × AC supply and delivers a rated output of 6 kVA at an S6 duty rated current of 10 A. U/f curve control shapes the voltage-to-frequency ratio up to a maximum of 2000 Hz, while the continuous S6 output reaches 5 kVA and short-term capacity rises to 7.5 kVA. Nominal S1 current is 8 A and the peak value stays within 13 A for 60 s. Forced air cooling moves 0.03 m³/s through the housing, and the assembly carries an IP20 degree of protection. An integrated mains filter limits conducted emissions, and a built-in brake chopper with an onboard resistor dissipates regenerative energy; the resistor handles 0.3 kW continuously, whereas the chopper itself can process 4.8 kW. Additional features include a 24 V external stand-by supply input, design generation 1 hardware, and compliance with a ±10 % line-voltage tolerance.

Thermal limits span 0 °C to 40 °C, allowing installation in standard shop-floor enclosures, and the weight is 20 kg for straightforward panel mounting. Brake-stage hardware is sized for transients with a continuous chopper rating of 4.8 kW and a resistor value of 60 Ω, while motor acceleration peaks draw 13 A and momentarily raise apparent power to 7.5 kVA. Output accuracy is maintained across supply fluctuations of ±10 %, and the converter’s functions remain active during control-power loss through the external 24 V stand-by input. Firmware is ordered separately to match application needs, ensuring that generation 1 hardware receives the correct code set.
