Abstract:
Method and device for controlling the electrical variables and/or LLM currents of LLM coils of an LLM stator, the movement of a first transport unit is controlled by an associated first transport controller, the movement of a second transport unit is controlled by an associated second transport controller, and a control unit checks whether the first transport controller intends to specify a first controlled variable for an LLM coil and whether the second transport controller simultaneously intends to specify a second controlled variable to the same LLM coil. In this case, either an additional controlled variable, which is derived from the first controlled variable and/or the second controlled variable using a predetermined function f (Ux=f(Ux′, Ux″), or Ux=f(Ux′) or Ux=f(Ux″)), is specified for the LLM coil, or the coil terminals of the LLM coil (Lx) are short-circuited.
