Parameterization of fan speed control

Today's exhaust gas emission regulations increase the demands on cooling capacity in combustion engines in on-highway and off-highway vehicles by up to 40 %. Hydrostatic fan drives from Rexroth supply this additional performance on demand while saving installation space. The AFC30 control solution from the Bodas electronic modular system by Rexroth requires only a simple parameterization. The fan speed control, which works on demand, reduces fuel consumption by up to 5 %. The fan speed control from Rexroth is based upon the controller RC4-5/30, which is in large-scale production, and the AFC30 application software. The software is simple to parameterize and it controls the fan power according to individual set point specifications, independent of the combustion engine speed. It also records up to six different temperature signals digitally via CAN or via connected analog sensors and adjusts the power accordingly.
