FIELD: lifting machines.

SUBSTANCE: control system for a passenger-and-freight elevator consists of a cabinet in which the controller is located, under it there are sequentially placed a control panel, an interface board that has a discrete connection with the controller. An overhead cable is connected to the interface board, a place for cable entry located in the central part of the front panel of the cabinet. Below is a power terminal rail for connecting power circuits. The controller is connected by a code communication line via the RS-485 interface to a frequency converter configured to monitor and control the electromagnetic brakes of the winch by means of a brake control device connected to the safety circuit and located in the main drive module with the main contactor. The main drive module is connected by a safety circuit to the interface board. The controller is connected to the brake control device, which is configured to communicate with the electromagnets of the winch brake device, through the interface board by the safety circuit.

EFFECT: enhancement of maintainability and reduction of overall dimensions.
