Chapter 4 Operation and Trial Running
- 37 -
When the door close position reaches (F6-09 x door width), the door machine decelerates
again to the speed set in F4-07. It is recommended that F6-09 ≥ 96.0%; reduce F6-09 if there
is pulse loss during door open/close.
Set the threshold for retracting the door vane in F6-20. After the door vane is retracted and
door limit is reached, the door machine enters the torque holding state, with the speed set in
F4-07 and holding torque set in F4-12. The door position is reset to 0.
After the door close command is cancelled, the torque holding state ends.
4.4.3 Door Close Hindered
Door close hindered means that one of the following conditions occur during door close:
•
Light curtain/safety edge signal active
•
Output torque larger than the door close hindered torque
•
Door open command active
If door close hindered occurs, the NICE900 processes this abnormality in two ways: decelerate
to stop or re-open the door, selected in F4-14. This abnormality is judged based on the time or
torque.

After the time reaches the deceleration time in F5-00, the controller re-opens the door at low
speed, and enters normal speed running state after the time set in F3-02.
After the door open slow-down signal is active, the controller enters the low speed running
state and opens the door to the open limit position, and then outputs the door open limit signal.
