1. Product Introduction
DO3000 permanent-magnetism frequency-conversion door operator is a door drive system which is driven
by the permanent magnet synchronous motor and controlled by stepless speed adjustment and frequency
conversion system. It can achieve the best open/close speed curve, with the features such as efficiency,
reliability, simple operation and less mechanical vibration. DO3000 permanent-magnetism
frequency-conversion door operator applies to the door system with the net door width of (700 ~ 1800)
mm.
Main characteristics are as follows:
1 Synchronous motor angle learning (static)
2 Door width learning
3 Automatic open/close demonstration
4 Fault alarm and automatic protection
5 Baffle detection selection
6 Synchronous/asynchronous door coupler selection
