The invention relates to a conveyor for passengers and/or goods, the conveyor comprising at least one linear electric motor formed by linear stator beams with stator poles being located in a fixed correlation to an environment, and at least one mover co-acting and moving along the stator beams, the stator beams comprising at least a first stator beam extending in a first movement path in a first direction of the passenger conveyor and at least a second stator beam extending in a second movement path in a second direction of the passenger conveyor, wherein the first direction and the second direction are different directions, selected from the group of horizontal, inclined and vertical direction, and which mover is adapted to face the respective stator poles of the stator beam, wherein the mover has at least one winding arranged to co-act with the stator poles; the linear motor being controlled by a motor drive, which is controlled by a drive control. The drive control comprises a set of control parameters, and whereby the drive control is configured to use at least partly different set of control parameters when associated with the first stator beam than with the second stator beam, and which drive control is further connected with an input for the position of the mover, and that the drive control is configured to select the control signals for the mover dependent on the location of the mover on either the first or second stator beam.
