AT120 Otis elevator parts door machine box FAA24350BK1 door machine inverter elevator door controller

Performance introduction

AT120 door operator consists of DC motor, controller, transformer, etc., which are directly installed on the aluminum door beam. The motor has a speed device and an encoder, and is driven by a controller. The transformer supplies power to the controller.
AT120 door machine controller can establish connection with LCBII/TCB through discrete signals, and can achieve the ideal door opening and closing speed curve. It is efficient, reliable, simple to operate and has small mechanical vibration. It is suitable for door systems with a clear opening width of no more than 900nmn.

It mainly has the following characteristics (the latter two require corresponding servers to operate):
- Door width self-learning;
- Torque self-learning;
- Motor direction self-learning;
- Menu-style interface;
- Flexible on-site parameter adjustment.
