The 12X provides the ability to adjust the speed of servos on
each channel in each direction. The speed may be reduced
(servo slowed) from its normal speed but it cannot cause a
servo to move faster than its rated specifications. Each servo
can have 2 sets of speeds in each direction that are Flight Mode
or switch selectable.
The servo speed function can be very useful for scale models
with retractable landing gear and gear doors, since in many
instances the need for gear door sequencers can be eliminated.
If the gear door servos move at normal speed and the landing
gear servos move at a slower speed when the gear is lowered,
the gear doors will be open before the landing gear begins to
come down. In the opposite direction, if the gear door servos
move slowly and the landing gear servos move at normal
speed, the gear can retract before the gear doors begin to close.
Note
: Many retract servos are non-proportional type
servos that simply move from end point to end point.
These types of servos are not adjustable in the servo
speed function.
24: Servo Speed
1. Highlight and select SRV. Speed. Speed FUNC.LIST.
2. Select SW SEL and press the roller to access Switch Select.
If only one servo speed is desired, then all selectable switch
positions in this screen should be P0. If two servo speeds
are desired, then assign the desired switch that will change
the servo speed to P1. Return to the main screen.
3. If a single set of servo speeds is desired, make sure the
display is showing Pos0. If it is not, select Pos1 and
change it to Pos0. Highlight and select the channel and
direction for each servo that is to be adjusted. Once a
direction for a servo is selected, the servo speed may be set
so the servo travels from .193 seconds for 60 degrees of
rotation to 16.4 seconds for 60 degrees of rotation. Adjust
the speed of each servo until the desired speed is obtained.
4. If 2 sets of servo speeds are desired that are Flight Mode
or switch selectable, one set of values is set to NORM for
all channels, and the slowing of servos can be turned off by
selecting the position (Pos0 or Pos1) that has the NORM
values. Highlight and select Pos0 and change it to Pos1
and then highlight and select the channel and direction for
each servo that is to be adjusted. Once a direction for a
servo is selected, the servo speed may be set so the servo
travels at the desired slower rate. Switch between Pos0 and
Pos1 to view and adjust the 2 sets of values for each servo.
Note
: Pos1 always has priority over Pos0. In other words,
if multiple switches are selected and one of the switches
is in its Pos1 position, then all other switches are ignored
and the Pos1 values are in effect.
