Servo Reverse; Servo Neutral - GRAUPNER mc-16 Programming Manual

SERVO REVERSE

Reversing the Rotation of the Servos
(access via Set-Up Menu)
Reversing the direction of servo rotation.
The set servo rotation is shown in the display for all
servo functions 1...8; you will see the cursor line
under either "REV" or "NORM". This eliminates the
need to reconnect plugs in the transmitter or reverse
the servos themselves. Press the
CH SEL
repeatedly until the required channel you wish to
alter appears in the display, then swap the direction
using the or buttons. The
INC DEC
will always reset the direction to "NORM".
Note:
The channel number refers to the receiver output to
which the servo in question is connected. Any
agreement with the numbering of the channel inputs
is coincidental, and is unlikely to be the case when
complex mixes are in use. For this reason a change
in stick mode does not affect the numbering and
direction of rotation of the servos.

SERVO NEUTRAL

POSITION
Servo Neutral Position
(access via Set-Up Menu)
This can be used to adjust for non-standard pulse
width servos (≠1.5ms) or other reasons.
The neutral position can be shifted within the range
±125 steps (approximately 70% travel) using the
"SB TRIM" option, regardless of the trim lever
button position and any mixer settings.
Select the channel you want to adjust using the
button and then press
CH SEL
button repeatedly to shift the centre point, until the servo
CLEAR
neutral is correct for you application. The
button can be used to reset the adjustment to 0, i.e.
the servo the return to its original neutral position.
This setting refers directly to the servo concerned,
and is not affected by other trim and mixer settings.
Servo Travel Adjustment
(access via Set-Up Menu)
The abbreviation "TRV ADJ" stands for Travel Adjust
and provides adjustment of servo travel separately
for either side of centre. The adjustment range is
0...160% of normal servo travel.
It can be determined from the block diagram what
impact this setting has on the servo concerned.
Some mixers are not affected by this setting as they
or feed directly into the „Input Point for Mixers", whilst
INC DEC
the output of others are adjusted according to this
setting.
CLEAR
Press the
servo function (1...8) appears in the display. The
bottom line of the display shows the servo travel set,
with the prefix (+ or -) indicating the side of centre. If
you wish to adjust (& display) a setting, you need to
move the associated control (stick, slider, switch) to
the relevant end-point. Adjust the travel with the
or buttons, and reset it to 100% with
DEC
SERVO TRAVEL
button repeatedly until the correct
CH SEL
CLEAR
