Detail program description - Control adjust
Control of temporal processes
using time delay and curve mixers
A useful, but less known capability of the mc-32
HoTT software is the ability to activate nearly any servo
movements with a maximum duration of 9.9 seconds
using a switch.
The programming for this should be shown on the
basis of some examples in the following. Additional
applications can certainly be found once you become
familiar with these capabilities.
The programming is begin in the menu …
"Control adjust" (page 96)
… and in order to be able to approach any point of
the control curve during the programming, fi rst assign
one of the proportional rotary controls to the desired
control channel – in this example CTRL 8 to the Input
9. However, leave the standard default "GL" in the
"Type" column so that this setting is effective for all
fl ight phases analogously to the free mixers to be
programmed in the following.
The input of a time delay in the "- Time +" column should
also be dispensed with initially:
Input 6

Then in the menu …
"Only mix channel" (page 193)
… of the selected control channel, "9" in this case, is set
to "Only MIX":
MIX ONLY CHANNEL
only

It is mandatory that this is set to "Only MIX", because
the control curves of the curve mixers described in the
following example only function on the output of the
same channel as desired if there is no direct connection
between the control and output! Only then can the linear
control signal be manipulated almost arbitrarily around a
curve mixer and to the appropriate output.
Therefore, in the next step, switch to the menu …
"Free mixers" (page 181)
… and program a curve mixer for the same channel,
e.g. from "9" to "9":

On this second screen the desired path of the control
curve is then set, whereby the following examples
should only be "food for thought" for the design of your
own control curves.
For example, the control curve could be for …
