power to power failure emergency run. After NICE 3000 chooses the way of power failure
rescue, it would run by emergency speed, the direction is the same to run direction of lift light-
load run. When detecting signal, it will open the door and stop working.
From the description above, for the synchronous motor, it can choose auto-running car, 48V
battery supply to run after the auto-running, or UPS
supply to run after the auto-running. For
the asynchronous motor, it can only choose 48V battery supply to run or UPS supply to run.
In order to distinguish the three modes mentioned above, their features are described in the
following chart.

We mainly introduce typical application of auto-running by the following chart. If use other way
(include rescue au
tomatically switch). You can contact with us.
