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.
