Intelligent programming aid:
If you wish to set up multiple tasks in order to move the wheel doors to
several positions, it should be obvious that the new task’s initial positional
value and start time are determined by the previous position and time for the
servo concerned. This is carried out automatically, helping to speed up the
programming procedure, and eliminates the need for you to note down the
servo’s previous position and stop time.
A similar situation applies when you set the retract process DOWN » UP.
When you set up the extend process UP » DOWN, the positional values for
Start and Stop for that servo are already entered as Stop and Start.
The following example demonstrates how one wheel door opens half-way
when the transmitter switch is operated, pauses for a while, then runs to its
end-point. When the switch is reversed, the door returns to its original position
in a single movement lasting three seconds.
UP » DOWN means undercarriage exten-
sion. Output 3 of the door sequencer has
been selected. The servo runs from its ini-
tial value of 1100 µs (right servo end-point)
to the stop value of 1500 µs (servo centre).
The servo only starts moving 1.0 seconds
after the switch is operated, and the period
is 3.0 seconds (4.0 s – 1.0 s).
Task 1 has now completed its course.
After a pause lasting 2.0 seconds at servo
centre, the servo starts moving in the direc-
tion of 1800 µs (left servo end-point). The
movement period is 2.0 seconds (8.0 s –
6.0 s).
Task 2 has completed its course.
DOWN » UP means undercarriage retrac-
tion. In this example, when the switch is
operated, the servo immediately starts
running slowly from the left to the right
servo end-point (Start time 0.0 s).
