ADJUSTABLE FUNCTION RATE (AFR)
This function is used to adjust the throw and
operation curve of the stick, lever, and switch
functions (CH1 to CH8) for each flight condition.
This is normally used after ATV has defined the
maximum throw directions (ATV acts on ALL
flight condition settings). When mixing is applied
from one channel to another channel, both chan-
nels can be adjusted at the same time by adjusting
the operation rate by AFR function.
In the AFR mode, the function operation rate
can be adjusted for each travel direction. The
servo's response curve can be changed so that the
control can be performed comfortably by setting
the EXP1/EXP2 modes. This is best understood by
examining the curves that the PCM 1024Z system
displays as the parameters are changed. The AFR
function may be programmed to have a rate varia-
tion from 0 to 140%; the EXP1/EXP2 curve rate
can be adjusted from -100 to +100%. With 0%,
exponential produces a normal straight-line
response.
In the EXP1 mode, the servo movement near
the neutral position can be made sensitive or in-
sensitive. EXP2 mode is applicable to throttle and
other control sliders and levers that do not self-
center, and changes the response shape at one end
of the control movement. The response rate can be
made steep or gradual. NOTE: if you activate the
throttle curve and pitch curve functions, the throt-
tle channel and pitch channel EXP curves are
overridden.
If the LIN mode is defined within the EXP1
mode, you can make an ordinary rotary servo have
similar motion to that of a linear servo. In other
words, the rotary servo moves more the further it
is away from neutral, to simulate a linear output,
which moves the same amount regardless of servo
position.

and then press the key of the channel you wish to set.

Input Rates
You can select the rates in both directions, which are
designated as "A" and "B". To enter the rate for Side A,
press the C key and use the rate setting keys F to El to
input your desired rate. The rate is initially set to 100%.
Press the numeric key nearest the rate you desire from
among the H (0) to M (100) keys. You can then
increase and decrease the selected value with the F(+)
and G (-) keys. Each key press adds or subtracts 1.
Set the movement up so that no binding occurs at any
extreme motions of sticks, knobs, or sliders. You may set
the travel to anywhere between 10 and 140%.
Now you will set up Side B's rate similarly. Press the
D key and set the rate with the rate setting keys F to
M. As before, use the numeric keys to get the travel you
desire.
Repeat this procedure for all the channels in sequence.
