Introduction

EC30 elevator door controller is a dedicated for elevator door systems. It's designed with smaller appearance structure, lightweight and compact size, ultra-thin plastic shell to be easier to install. It also has a wide range of applications and meets the needs of various elevator door control.

Features:
* Support induction and PM motors, incremental and absolute encoders
* Fully pulse running mode without limit switches, intelligent processing while pulse loss
* Auto speed curve generation without parameter adjustment
* Fully Comply with CE certification
* Advanced functions such as One-button debugging, obstacles detection, auto demonstration, and self-adaptation to working conditions.

Customer Requirements

The client, a provider or integrator working with Schindler elevator systems, required a modern and compact elevator door control system that could replace or integrate with existing Schindler door headers due to AMC fail. The aim was to enhance door control performance, reduce commissioning time, and ensure high compatibility with contemporary elevator standards.

* Challenges:
• Need to integrate EC30 controller with Schindler’s proprietary door mechanism.
• Ensure compatibility with both synchronous (PM) and asynchronous motors.
• Require precise control via encoder feedback without limit switches.
• Simplify commissioning and maintenance processes.
• Maintain compliance with CE certification and safety regulations.

INVT Solutions

• Deployment of INVT EC30 Door Drive paired with DM30 Motor.
