Abstract
A method for controlling a direct drive transmission system and related devices. The method includes: S1: starting direct drive transmission system for overall zero returning; S2: reading a zero signal of the first incremental position feedback means identified by a corresponding second incremental position feedback means; S3: determining whether any actuator reads two zero signals; if yes, performing step S4; otherwise, returning to step S1; S4: determining according to a distance between two zero signals fed back by the actuator that the corresponding mover has completed zero returning, and further completing zero returning of the direct drive transmission system; and S5: acquiring, by the controller based on the direct drive transmission system after zero returning, position information of the movers, and driving the movers to move. Compared with the related art, the present disclosure has good position feedback effect, high positioning accuracy, and good drive control effect.
