Safety

  • Anti-opening, safety protection for passengers in case the elevator has trouble or when the cabin stops deviating from the floor.
  • Function to protect people and obstacles (when the door is closed with enough resistance, the door automatically opens).
  • Keep the door closed and keep the door open to prevent vibration / openings.

Convenient

  • The EC20 comes standard configured with just connection and commissioning.
  • Compatible with ABZ push-pull or open collector output encoder.
  • Din-rail compact design saves space.
  • Advanced control terminal, friendly interface, easy to install and operate.

Clever

  • Features the acceleration / deceleration by position, making the door open and close fast and very smoothly.
    • Multi-level speed control according to position sensor and limited switch.
    • Control position by distance using Encoder with Switch limit
    • Control position by distance using Encoder without Switch limit.
  • Automatic function to learn the door travel width.
  • Integrate timers in all stages of control.
  • Receive open / close order and output relay signal to close and open the door.
  • Communication: CAN bus, MODBUS.
Flexible application
  • Compatible with many different types of doors.
  • Communicate with multiple lift control systems.

Control modes of inverter EC20:
EC20 has 3 control modes for main door:

  • Speed ​​control with 2 limit sensors and 2 deceleration sensors, along with 2 simulated reducer sensors in the inverter, helps the door operate gently when decelerating.
  • Position-based speed control with position feedback from the encoder motor and 2 limit sensors, makes the door operate fast, accurate and smooth.
  • Position-based speed control with position feedback from the encoder motor and no limit sensor, helps the door operate quickly, accurately and smoothly, saving costs.
