The Bosch Rexroth R911200433 (RD51.1-4N-090-L-C1-FW) is a motor controller with V/f control features and additional function capabilities, including a connection for the RZC01.1-XN and 24 Volts standby power. The latter allows for parameterization and operation of its control electronics, even without AC input. For enhanced safety, it's recommended to apply this power to X83 in a floating manner to prevent reverse polarity risk. The device draws from a 380 to 480 Volts AC rated converter and doesn't feature a brake chopper. Offering an optimal output of 90 and 75 kilowatts at 4 kilohertz and 8 kilohertz pulse frequencies respectively, its rated current varies depending on pulse frequency. The unit's efficient forced-air cooling system requires a minimum of 0.4 m3/s cooling air for effective heat dissipation. Weighing in at about 74 kg, this device is shipped globally with a one-year warranty from Indramat USA.
