摘要:
There is provided a control device for an elevator capable of quickly calculating an exact inertia according to an operation mode of elevator considering whether the operation mode of elevator is a power running operation or a generative running operation, and having good followability. In a control device for an elevator including a speed command inputting unit for sending a speed command to a power unit; a speed detector for detecting the actual speed of the power unit; and a torque controller for calculating a necessary torque based on the speed command and the actual speed, and sending a torque signal to drive the power unit, there are further included an initial parameter setting unit for setting the initial value of parameter of the torque controller in advance; an operation mode judging unit for judging whether the operation mode of power unit is a power running mode or a generative running mode; an inertia calculating unit for calculating the actual inertia value based on the speed command, the actual speed, and the torque signal, and the operation mode; and a parameter correcting unit for correcting the parameter of the torque controller by using the actual inertia value.
