Product Description:
The RD51.1-4B-004-L-NN-FW by Bosch Rexroth Indramat is a RD 500 drive that performs control functions in industrial motion tasks. It is designed to convert input signals into fine-grained control signals that direct the performance of motors based on real-time application demands. It forms a key component in motion processes that require adaptable speed and torque output to match dynamic load requirements. The drive facilitates accurate control over the motor’s rotations, ensuring that the velocity and torque output correspond to the specific load. This enhances system productivity and also minimizes energy wastage by ensuring that output is sufficient for the connected load.
The RD51.1-4B-004-L-NN-FW drive is designed to work efficiently with different motor types. Its rated current of 9 A supports stable operation in medium to heavy-load tasks without generating excess heat during operation. This helps to keep operating conditions steady for consistent system performance. In extended operation, the drive’s built-in fan keeps heat from building up in the drive by circulating air within the drive. This efficiently keeps hot air out of the system while drawing in cool air. This protects the drive and connected components from thermal stress, ensuring reliability even when the drive is subjected to extended duty cycles or very high loads.
The RD51.1-4B-004-L-NN-FW’s 4 kW mechanical output is suited for energy-sensitive settings that require robust performance without excessive loss of power. The capacity is sufficient for powering connected motors, ensuring tight control over the velocity and torque of the motor. For stable performance, the drive requires a three phase power supply within a range of 380 V up to a maximum limit of 480 V. It can withstand slight ±10% variations from this range, ensuring that minor faults in power supply do not affect performance.
