The signal is input to the speed control amplifier 52 shown in the figure. The following operations are controlled in the same manner as normal elevator operation. However, since the main circuit does not have a power source, only the charge stored in the capacitor 31 is used, and the main circuit voltage decreases. If this is detected by the voltage detection relay 34 and the voltage is set to be demagnetized when the voltage drops to the voltage of the backup battery itt source 35, the contactor 36 shown in FIG.
A is turned on, power is supplied to the main circuit from battery G35, and operation can be continued.

に示す。In this case, the speed command value for rescue operation must be set to a speed that allows operation with battery voltage. Normally, in the primary frequency control of an AC motor, in order to obtain the same torque, it is necessary to control the ratio V/f of the supplied voltage V and the operating frequency f to a constant value, so the main circuit battery voltage VB and rescue The operating speed SB must be set as S with respect to the DC voltage ■N during normal elevator operation and the rated speed SN in the relationship Va/Ss≧VN/SN. Continuing the operation in this way, when entering the door zone, the relay 47 is energized, the A appliance 50 is demagnetized, the relay 51 is energized, and the switch 51c
conducts. In this case, the voltage set by the variable resistor 61 and resistor 63 is input. This set voltage is set lower than the set voltages at the variable resistor 60 and resistor 62 described above. Then, the speed command pattern decreases, the speed also decreases, and when the vehicle enters the :R floor zone, the relay 49 is energized, the relay N switch 51 is deenergized, the switch 51c becomes non-conducting, and the speed command becomes zero. At the same time, the relay 23 is demagnetized and the brake is applied to stop the elevator. In this way, the elevator continuously shifts to the rescue operation and ends the rescue operation. In this case, the voltage waveforms at points ■, ■, and ◎ in FIG. 4 are shown in FIG.

ととなる。Even if the elevator is running down, the relay 42
is replaced by the operation of the relay 44, and the speed command pattern passes through an inverting amplifier composed of an operational amplifier 67 and resistors 72 and 73, resulting in the same operation except that the polarity is reversed. In addition, if a power outage occurs while the elevator car 6 is inside the door zone and outside the landing zone, the resistor 63 and the variable resistor 6
1, and will not operate if the elevator 6 is within the landing zone.

ことができる。As mentioned above, if a power outage occurs while the elevator is in operation, the control circuit is immediately backed up with backup power, and the operating speed command is switched to the rescue operation pattern in the operating direction before the power outage. Passengers can be rescued by shifting to rescue operation without stopping the elevator, thereby improving service by minimizing passenger anxiety.
