The NICE900 series door operator controller is a dedicated variable-frequency drive controller designed specifically for elevator door systems. By integrating door logic control and motor drive control, the NICE900 allows external systems to control the entire door system simply by sending open/close commands.

The controller is compatible with both AC asynchronous motors and permanent magnet synchronous motors, supporting speed control and distance control modes, making it suitable for a wide range of elevator door applications.

Key Features of the NICE900 Door Drive Controller

Integrated asynchronous and synchronous closed-loop control for precise and stable operation.

Flexible control via communication or IO for efficient and safe operation.

One-button commissioning with automatic curve generation for simple and user-friendly setup.

Door blade distance learning for smoother and more accurate movement curves.

Comprehensive protection functions including over/under voltage, overcurrent, phase-to-phase short circuit, output phase loss, and anti-pinch protection during power outage.

Adaptive holding torque to maintain the dynamic balance of the door system.

Door system inertia recognition to automatically assess kinetic energy, friction, self-closing force, and constrain drive output for safe and precise operation.

The NICE900 series provides an intelligent, reliable, and easy-to-use solution for elevator door systems, enhancing safety and comfort while simplifying installation and maintenance. It is an ideal choice for modern elevator projects.
