Abstract: A control system for a passenger conveyor includes a ready-to-operate mode, a standby speed and a nominal speed. A method to operate the passenger conveyor includes the steps of: transitioning the conveyor from ready-to-operate mode to nominal speed using a frequency converter; switching from frequency converter to line power at nominal speed; switching back to frequency converter if no passengers are present and transitioning from nominal to standby speed; and transitioning from standby speed to ready-to-operate mode if a predetermined amount of time passes without a passenger entering the conveyor.

Abstract translation: 用于乘客输送机的控制系统包括即时操作模式，待机速度和标称速度。 操作乘客输送机的方法包括以下步骤：使用变频器将输送机从即时操作模式转换到额定速度; 从变频器以额定速度切换到线路电源; 如果没有乘客存在并从标称到待机速度转换，切换回变频器; 并且如果在没有乘客进入输送机的情况下经过预定量的时间，则从待机速度转换到即时操作模式。

Abstract: A method of controlling the drive of conveyor installation comprising a the drive motor (26) and a frequency converter (42) whose output is adjustable, between a load operation and an idle mode, in the form of an escalator (10) or a moving sidewalk, where: in the load operation mode the drive motor (26) is supplied with a line voltage at an essentially constant line frequency (fNetz), and in the idle mode with an output voltage of the frequency converter (42); the line voltage and the frequency converter's output voltage are compared with respect to frequency and phase position; the frequency converter (42) is set for an output frequency which has a predetermined spacing (Δfup, Δfdown) from the line frequency (fNetz);a demand to switch modes is signalled by a conveyance signal generator (48);and at the point in time (t1, t4), after a demand to switch modes has been signalled, when the output frequency of the converter (42) has reached the predetermined frequency spacing (Δfup, Δfdown) from the line frequency (fNetz), and a predetermined phase spacing has been achieved between the frequency converter's output voltage and the line frequency (fNetz), a switch-over signal (58) is emitted to switch the drive motor (26) between the frequency converter supply and the line supply.
