The speed control unit is a very important element of elevator controllers. The main purpose of these units is the steady-state error or disturbance rejection. Speed control systems carry a very important part of Direct Current (DC) motors. As elevator motors are used for variable speed drives, speed control units are used to control these different speed types.
As ISF Elevator Company, we believe that all the parts of elevator systems should be of the highest quality. We use the best control units in our whole elevator systems. We can also provide them individually.
