Abstract (en)

[origin: EP0679452A1] The operating process is for a direct multiple traction machine. The values or signals required for control and adjustment depending on the process are taken from the drive, from among the following:- revs. (n.10) and torque (n.11) or revs. (n.10) and current (n.11), or revs. (n.10) and load (n.11). A separate process for each drive is used to take the actual running values such as velocity of material (n.10) and force (n.11) corresponding to the design values of the block (n.1) and the drive (n.3), and the physical connections relating to the form of drive, such as DC and AC drives. <IMAGE>
