Servo outputs
The SFR-1 offers two servo outputs (X5/1 and X5/2).
The servo outputs deliver usual pulses from 1,000 - 2,000ms, so you can connect
standard servos or speed-controllers.
The power supply for these servo outputs is the integrated BEC of the SFR-1.
There are two different ways to control the servo outputs:
1. Driving to fixed positions
2. Running through a programed sequence
Driving to fixed positions:
For each servo, up to five positions can be specified in the Sound-Teacher (see
page 77), which can be approached via the freely assignable functions of the sound
module. The positions have the following names:
• Home position
• Position #1
• Position #2
• Position #3
• Position #4
Running a programed sequence:
A flow sequence can be programmed for each servo output in the Sound-Teacher.
Conceivable applications are e.g. a recoil system for a tank or an easy windshield
wiper for a truck.
A servo sequence can be triggered with the functions “Servo 1 sequence“, “Servo 2
sequence“ or with a sound (e.g. a cannon shot). A detailed description of the servo
sequence can be found on page 80.
A servo output can only be controlled either to a fix positions or as a sequence. Both
versions are not possible at one servo output.
The servo movement can also trigger a sound. The additional sounds “Sound from
servo 1/2“are responsible for this. It also distinguishes between left and right
movement. So you can play for every direction of running a different sound.
If you don’t want sounds while moving the servos, just leave these sound-slots
empty.
