PCT No. PCT/EP97/04451 Sec. 371 Date Mar. 30, 1998 Sec. 102(e) Date Mar. 30, 1998 PCT Filed Aug. 14, 1997 PCT Pub. No. WO98/08702 PCT Pub. Date Mar. 5, 1998An improved control device for linear-motor-driven equipment, in particular for the drive of tenters of a film stretching plant, has a central control device (1) and a multiplicity of converters (11) that are activated thereby, at least indirectly. An improvement is achieved by a phase profile, which describes a relationship between the phase angle, the current amplitude and a clock pulse, for activating the stator winding (7) in a relevant zone (5), being able to be predefined for the converters (11), and by the corresponding phase-profile data for the activation of the stator winding (7) being able to be calculated and/or generated in the converters (11). In addition, a synchronization device, via which the time signals in the converters can be synchronized with one another during operation, is provided.
