Why Use Servo Based Elevator Car Door Controller Instead of VVVF Controller?

Our door controllers serve plenty of elevator brands also including OTIS Elevators.

You may benefit the following advantages of servo based car door controllers,
  • High accurate position control.Servo control system can improve an order of magnitude precision higher than that of other door control systems.
  • Intelligent control of the closing door can be realized to ensure the safety of passengers.
  • A variety of functions of program (auto tune, opening, closing, close door force detection, close door force maintenance, and fire fighting operation) improve the  performance of the door machines.
  • Synchronous door knife technology, ensure  the sychronous open/close operation of both of the doors of the hall and car.
  • Adopt synchronous belt mechanical transmission, structure simple and low noise.
  • Eliminate door wide limit/
  • Full software programming& digital control realizes the most reliable&safe control system.
  • Available for different elevator manufacturers.
  • Free of maintenance and long service life .
  • The most optimized,smooth speed control.
  • Safe return function (anti-pinch) .In case a person is squeezed during closing door, the control system immediately detects the change of the feedback torque and the door will be opened in the opposite direction to ensure the safety of the personnel.
  • Anti-pull function . When the door is closing normally, the controller close the door tightly with low speed and small torque. In case the special torque changes are detected (someone’s door, etc.), immediately force the door to close, and will be automatically withdrawn  under the normal condition.
  • Auto tune( self -learning) functions. According to different specifications of the door and open width and different operation state, the control systems carry out the automatic self-learning program to record the action position of the door.This function runs automatically every time the power is on, and  specify the initial state of the gate.
  • Friendly human-computer interface.
