Speed control device for an elevator |
摘要 |
An elevator speed control device in which the cage of the elevator can be stopped at a desired floor with a high accuracy without increasing the capacity of power supply equipment to compensate for periods of low AC source voltage. A detecting circuit produces an output signal in response to the generation of a deceleration instruction signal. This signal is converted into a short duration pulse signal which is used to set the output of an integrator included in the control circuit loop to a predetermined value.
