Controlling timed sequences
using time delay and curve mixers
An interesting but little know possibility with the soft-
ware of the mc-22(s) is the facility to apply a delay of
up to 9.9 seconds to virtually any servo movement,
controlled by a switch.
The following section includes a number of examples
which illustrate how such systems can be program-
med. Once you have become familiar with these facili-
ties you will undoubtedly think of other applications.
The fi rst step in the programming is to move to the
menu …

… where you assign one of the standard sliders to
the control channel you wish to use; the slider is then
used as a tool to move to any point on the control cur-
ve during the programming procedure. In our example
this is transmitter control 7 assigned to channel 9. Ini-
tially you should not enter a time delay in the “-Time+”
column.
Next we move to the menu …

…where the selected control channel – in our examp-
le “9” – is set to “MIX only”.
Setting the control channel to “MIX only” is absolutely
essential, because the control curves of the curve mi-
xers which are described in the following example can
only infl uence the output of the same channel in the
way we want if there exists no direct connection bet-
ween the transmitter control and the output. Once this
requirement is met, we can manipulate the transmit-
ter control signal in almost any way on its detour via
a curve mixer, before it is passed on to the appropria-
te output.
For this reason the next step is to move to the menu

… where a same-channel curve mixer is program-
med, e.g. from “9” to “9”. On the second page of the
menu we defi ne the desired shape of the control cur-
ve; please note that the examples shown here are
only intended stimulate your own ideas for designing
control curves to suit your particular application.
For example, the control curve for …

red that it works correctly – you can check this at any
time by switching to the »Servo display« menu –
