Product Description

The Bosch Rexroth RD52.1-4N-022-L-NN-FW is a drive system designed for motor control applications. It is part of the RD52 series which features drives based on AC converters or DC inverters. The RD52.1-4N-022-L-NN-FW is based on a converter rated for 380 to 480 Volts AC (three-phase) input. The drive converter includes a mains filter but does not include a brake chopper. The nominal rated power output of the RD52.1-4N-022-L-NN-FW drive system is 22 kilowatts. Extra features are not available on the drive. Optional features that can be ordered if required include feedback of current filter, feedback of cable damping, frequency converter, 24 Volt standby power and 95 mm² terminals. The RD52.1-4N-022-L-NN-FW has an IP20 protection rating. All metal parts of the switch cabinet should be connected with one another through the largest possible surface area.

The signal, line supply, motor and power cables for the RD52.1-4N-022-L-NN-FW should be routed away from each other to eliminate mutual interference. Contactors, relays and counters in the cabinet should be provided with noise suppression devices. The shields of signal cables should be connected to ground at both ends. The RD52.1-4N-022-L-NN-FW drive operates at high voltage levels. All work on the drive system should be performed when the drive system is not under power. The work should be carried out by qualified personnel. The DC link capacitors should be allowed to discharge fully before any maintenance activity is carried out. At 4 kilohertz pulse frequency, the continuous and peak output current ratings are 43 Amps and 55 Amps respectively. The rated power loss is 0.8 kilowatts. The cooling air requirement is 0.1 cubic meters per second. Weight of the drive system is 36 kilograms. This product can be shipped globally with a one year warranty period from Wake Industrial.
