Abstract: A moveable body (16) is guided in non-contacting fashion by exercising control by a guidance control unit (C1) constituted by zero power-control means (unit) (L2) and stabilization unit (L1) of a magnetic levitation system (C2) comprising guide rails (14) and (14′) and magnetic units (30) mounted on the moveable body (16); also there is provided output limiting unit (C3) whose output value is limited based on the output value of the zero power control means (unit) (L2) itself. Improvement in the comfort of the ride is thereby achieved by expanding the allowed range of external force under which non-contacting guidance can be achieved. Also, increase in size of the magnetic units or reduction in the width of the designed gap length in order to cope with external force is thereby avoided, lowering the costs of the elevator system and enabling reliability to be improved with diminished frequency of contact with the guide rails.

Abstract: 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.
