Chapter 6 Description of Function Codes

5. After door vane retraction is completed and the rotor is locked, the door machine enters
the torque holding state at the speed set in F4-07 and holding torque set in F4-12. The
door width is reset to 0.
6. After the door close command becomes inactive, the torque holding state ends. If torque
holding needs to continue, decrease the delay time in F5-05.
7. The dotted line part in the gure indicates the door close running curve when F5-06 (Door
open curve) = 0 (Linear acceleration/deceleration).
For synchronous door vane, set F4-09 and F4-07 to the same value.
Function Code Parameter Name Setting Range Default Min. Unit
F4-07 Door close limit low speed 0.0 to F4-03 1.00 Hz 0.01 Hz
It is used to set the target frequency at which the door machine runs when the controller
receives the door close limit signal or the pulses reach the door close limit requirement during
door close.
Function Code Parameter Name Setting Range Default Min. Unit
F4-08
Low speed running time at
door close limit
0-9999 ms 300 ms 1 ms
The door machine runs at the low speed set in F4-07 after receiving the door close limit signal.
When the running time is equal to or larger than F4-08, the door machine enters the door vane
retraction stage.
Function Code Parameter Name Setting Range Default Min. Unit
F4-09 Door vane retraction speed 0.00 to F4-03 2.00 Hz 0.01 Hz
It is used to set the running speed at the door vane retraction stage during door close.
Function Code Parameter Name Setting Range Default Min. Unit
F4-10 Door vane retraction running time 0-9999 ms 500 ms 1 ms
If the door vane retraction running time is equal to or larger than F4-10, the door machine
decelerates again.
Function Code Parameter Name Setting Range Default Min. Unit
F4-11
Torque switchover threshold at
door close limit
0.0%–150.0% 50.0% 0.1%
It is valid only in distance control. After the door vane is retracted, if the controller output torque
is greater than F4-11, the controller resets the door width to 0 and enters the door close limit
torque holding state.
Function Code Parameter Name Setting Range Default Min. Unit
F4-12 Door close limit holding torque 0.0%–150.0% 30.0% 0.1%
