S.BUS SERVO USAGE PRECAUTIONS
• Current consumption: The S.BUS servo is designed to be used with models which
require especially high torque and high speed, the same as conventional digital ser-
vos. For this reason, a large current flows during servo operation. Therefore, decide
the safe number of uses by paying careful attention to the remaining battery capacity.
• Power supply: Use a battery with an ample margin as the power supply. The speci-
fied performance cannot be displayed with a dry cell battery.
• Operating angle: Install the servo so that the pushrod does not bind or become
slack even when the servo is operated up to its limit, or set the maximum travel using
the functions (ATV, EPA, etc.) of the digital proportion set or of the servo itself. Refer
to the instruction manual of each product and its setting program for a description of
the digital proportional set and servo setting method.
• Applicable models: The S.BUS cannot be used with transmitters (servo neutral sig-
nal: 1310µs) manufactured before 1982.
 CAUTION
 Do not touch the servo case immediately after servo opera-
tion. You may be burned because the motor and circuits inside the servo
become hot.
 Do not turn the servo horn with unreasonable force. If the
servo horn is turned with unreasonable force, the servo may be damaged.
 Do not expose the servo to dust and water. The servo does not
have a waterproof construction. If it gets wet, the servo may not operate
or the power supply may short circuit.
 Do not disassemble or modify the servo. The servo has a preci-
sion construction. Futaba Corp. will not be responsible for any disassem-
bly or modification other than those specified by us.
 Never connect the battery in reverse. Reverse connection may
cause smoke, fire, and damage.
 Do not leave the servo in the locked state. Leaving the servo in
the locked state (state in which enough force is applied that the servo can-
not move), may cause the generation of smoke, sparks or damage.
 Use the servo as an actuator in hobby applications. Futaba
will not be responsible if the servo is used in applications other than the above.
Futaba will not be responsible for damage, etc. caused by the use of
parts other than Genuine Futaba parts.
Programmable functions
The operating characteristics can be changed by PC-Link program
installed on a PC by using the CIU-2 USB serial interface to connect the
S.BUS servo to the PC. The set operating characteristics are effective for
both conventional radio control systems and the S.BUS system. (Some
functions are compatible with only one system)
How to obtain the PC-Link program
PC-Link programmable devices setting program for various models can be
downloaded for free from our website. Refer to the instruction manual for
each program for the operating instructions for each program.
Settable functions
The following operating characteristics can be set by PC-Link program.
[S.BUS servo setting parameter example]
Channel assignment / Servo reverse / Servo type / Soft start / Stop mode
/ Smother / Neutral offset / Speed control / Dead band / Travel adjust /
Boost / Damper / Stretcher, etc.
* The setting parameters differ depending on the model of the S.BUS servo.
* Refer to the PC-Link instruction manual for other functions and detailed setting contents.
• System use: The simple wiring S.BUS system can be used by connecting the S.BUS
servo to an S.BUS compatible receiver. In addition, the various operating character-
istics as a programmable servo can be changed by connecting the S.BUS servo to a
PC by using a CIU-2 USB serial interface.
