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
extension. Output 3 of the door
sequencer has been selected. The
servo runs from its initial 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
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 direction of 1800 μs
(left servo
movement period is 2.0 seconds
(8.0 s – 6.0 s).
Task 2 has completed its course.
