Abstract
PLC control of the elevator speed inverter current implementation, the speed of double-loop, based on the use of rotary encoder pulse signal issued constitute a position feedback, so that the lift to reach the precise displacement control. Control system implementation with current, velocity and displacement of three-ring control.
