摘要： A method of adjusting an elevator speed comprising the steps of determining a desired creep period, determining an actual creep period, determining a difference between the desired creep period and the actual creep period, determining a deceleration time for minimizing the difference between the desired creep period and the actual creep period, and adjusting the elevator speed in response to the deceleration time.

摘要： An elevator drive fault detector for detecting operational faults in an elevator drive having an inverter and only one circuit breaker includes a current sensor, a monitoring device, a control device and an operational control system. The current sensor provides a current sensor signal. The monitoring device determines if an operational fault exists in response to the current sensor signal and provides an operational signal. The monitoring device disables the operational signal if the monitoring device determines that an operational fault exists or if the elevator drive fault detector performs a system check operation. The operational control system provides both the run command and an operational check signal and is responsive to the operational signal such that if the operational signal is disabled then the operational control system opens the one circuit breaker and disables the run command such that the control device disables a PWM signal. If the operational signal was disabled during a system check operation then the operational control provides the operational check signal to the monitoring device such that if the monitoring device does not receive the operational check signal within a predetermined time then the monitoring device continues to disable the operational signal and the drive is elevator shutdown.
摘要翻译：一种用于检测具有逆变器的电梯驱动器中的操作故障的电梯驱动器故障检测器，并且仅一个断路器包括电流传感器，监视装置，控制装置和操作控制系统。电流传感器提供电流传感器信号。监视装置根据当前传感器信号确定是否存在操作故障，并提供操作信号。如果监视装置确定存在操作故障或者电梯驱动器故障检测器执行系统检查操作，则监视装置禁用操作信号。操作控制系统提供运行命令和操作检查信号，并且响应于操作信号，使得如果操作信号被禁用，则操作控制系统打开一个断路器并禁用运行命令，使得控制装置禁用一个PWM信号。如果在系统检查操作期间操作信号被禁用，则操作控制向监控装置提供操作检查信号，使得如果监测装置在预定时间内没有接收到操作检查信号，则监视装置继续禁用操作信号信号和驱动器是电梯关机。

摘要： Method for controlling the drive of a conveyor device (10), especially in the form of an escalator or moving sidewalk, switchable between load operation and no-load operation, having a drive motor (26) and a frequency changer (42) controllable at least with respect to frequency and phase position of its output voltage, in which the drive motor (26) in load operation is fed with a line voltage with essentially constant line frequency and in no-load operation with the frequency changer output voltage, the phase difference between the phase position of the line voltage and the phase position of the frequency changer output voltage is determined, the phase position of the frequency changer output voltage is corrected according to the determined phase difference and therefore essentially brought into agreement with the phase position of the line voltage and switching is produced as soon as this agreement is reached.
