3. Servo cycler
In this application it is possible to set the number of cycles, the servo throw and the cycling
speed. This item serves for verification of longevity, burning in and function tests of servos.
Connect batteries and servo and choose by means of push-buttons L and R the function
SERVO CYCLE.
By push-buttons U and D set the number of cycles from 10 to 990 (setting in steps of ten
cycles).
The speed can be set from 1 to 99 by push buttons L and R. A speed of v=1 means that
every following pulse in comparison with the foregoing pulse will change by 0.001ms until
you reach the limit position. (Analogous v=20 means a change by 0.020ms). The pulse
period is 20ms.
By means of push-buttons U and D a value can be set which defines the servo throw in μs
going from 100 to 500μs from the centre position of 1.5ms.
If the setting is a=500μs the control pulse for the servos will change from 1.000 to 2.000ms
(i.e. 1.500ms+-500μs). The value after the # gives the number of cycles which are still left
until the end of the test.
When the test is finished, the program returns back to the start SERVO CYCLE.
4. Measurement of servo transfer speed
By means of this test we can find out how much time the servo needs to transfer from one
defined position to the other one. Measurements can be carried out without load or with
the servo directly installed in the model at real lever conditions.
The pulse width of the first limiting servo position can be set within a range of 1.024ms to
1.400ms and the second one within 1.600ms to 2.047ms. If we want to measure the speed
when the servo output shaft turns for instance by 60°, we have to adjust this angle for
instance with a protractor.
Connect the battery and the servo, by means of the push-buttons L and R select the
function SERVO SPEED.
By means of the push-buttons U and D set the first limit position of the servo. Proceed with
push-button R until you reach the second limit position, which also must be adjusted by
push-buttons U and D.
Start the test.
On the display you will read the resulting time in seconds, which the servo needs for the
transfer from one set position to the other one. This measurement can be repeated several
times or you can set different limit positions.
