"EPA" function: setting the maximum servo deflection
This function can be used to determine the maximum permissible deflection
for the steering, throttle or auxiliary servo on each side (EPA = "end point
adjustment").
This feature is typically used to protect the mechanical system of a fully
deflected servo from hitting an obstacle mechanically.
You can set a value from 0% to 120%. The smaller the value, the shorter the
servo way on the corresponding side.
Try to organise the mechanical control via a servo so that the EPA setting
values of 100 – 120% can be used.
The direction of rotation of the servo (or setting for speed controller) can be
limited depending on the model you use.
Set the maximum possible steering deflection for steering so that the steering
servo does not bump and hum. Should a lower steering deflection be required
for subsequent operation (for fast or slow driving), it can be adjusted with the
so-called "dual rate" function.
If you use an electronic speed controller for the drive function, you can also set a maximum control value. However,
in order to be able to use the highest motor speed possible, you should not set a value of 100% for both directions.
To make a car model slower for a beginner, set a smaller value for forward driving (for example, 70%). The brake
function (or reverse driving) can be set to 100%, so you have the maximum braking force for a speed controller with
brake function.
Before limiting the steering servo deflection with the EPA function, you should first check if the factory
setting of 100% is still stored in the dual rate setting.
Proceed as follows:
• If you press the knob (14) briefly, the
MODEL
function will be greyed out.
•
Turn the knob (14) to the left or right until the
EPA
function is greyed out, as
shown in the right figure.
• If you press the knob (14) briefly, the channel number 1 will flash at the bottom
of the display.
"ST" (= "steering") also flashes for channel 1.
"TH" (= "throttle") also flashes for channel 2.
"AUX" (= "auxiliary" = auxiliary channels) also flashes for channels 3 – 6.
•
To set the left or right end position, move the control of each channel to the left
or right. The display will show the corresponding indication:
Left end position = "L.F.U." (= "left, front, up")
Right end position = "R.B.D." (= "right, back, down")
• If you press the knob (14) briefly, the setting value for the servo deflection (for example, 100%) will flash at the
bottom right of the display.
