The door drive controller EC-LD-180 is designed to control a synchronous drive motor in the opening / closing mechanisms of elevator doors and operation under the control of the following elevator stations:
- of SHUL type: SHULK, SHULM, SHULR;
- of UL type: UL, UKL, UEL, SHLR.
The controller is powered from a single-phase power supply grid of 220 V (+ 10%, -15%) with fundamental frequency of 50 Hz ± 1%.
The controller carries out the following functions:
- control of synchronous motor with rotor position sensor;
- determining the current position of the doors and the presence of an obstruction using a connected photocell or by exceeding the torque generated by the motor to close the door;
- outputting limit stop switches signals about achieving open and close states of doors, as well as the presence of obstructions in the doorway;
- disabling the mechanical lock of the elevator door in case of power failure;
- overvoltage protection, current / torque limitation of the motor, the formation of the required law of motion.
Specification is shown in Table 1.
