text: <s>[INST] Load Sharing in DC Powerflex Hello to everyone. I have 3 old DC Drivers running on load sharing (paper machine). These old drivers have Load Sharing function, but these function need to be turned on manualy (relay). The bigger motor are 400 HP for yankee dryer, 300HP for cylinder dryer and 150HP for crescent former. The yankee dryer operates as master to cylinder dryer and load sharing. And cylinder dryer as master to crescent former motor. Cylinder dryer are pressed against yankee dryer and crescent former motor are pressed against the rear roll of cylinder dryer section, and the three motors need to stay ate the same speed (syncronized). Reading the Powerflex DC manual, did not see any mention of Load Sharing function. Searching for any documentation about this funciont, found a Rockwell PDF called Load Sharing Applications for AC Drives. In this paper, they describe three forms of Load Sharing, but one im particular seems to be more similar to what i have here. Called Speed Trim Follower, describe 3 drivers where one are driven from torq referece from master and the other one driven from torque reference from the second one. My doubt is: This principle is applyed to DC Powerflex? Because of no single mention of this function in the manual, i need to ask if someone here have already work with this purpose with DC Powerflex. Best regrards, Rafael Mendonça. [/INST] Hello, one of the most common load sharing techniques is the speed leader/torque follower described previously. That principle is also applicable to the PowerFlex DC drives. There is further detailed information available from Load Sharing between PowerFlex DC Drives where key parameter settings are described. \\n </s>
