• Boost ON/OFF
OFF : It is the boost ON at the time of low-speed operation.(In the case of usual)
ON : It is always the boost ON.(When quick operation is hope)
• Damper
The characteristic when the servo is stopped can be set.
When smaller than the standard value, the characteristic becomes an overshoot characteristic. If the value
is larger than the standard value, the brake is applied before the stop position.
Especially, when a large load is applied, overshoot, etc. are suppressed by inertia and hunting may occur,
depending on the conditions. If hunting (phenomena which cause the servo to oscillate) occurs even
though the Dead Band, Stretcher, Boost and other parameters are suitable, adjust this parameter to a
value larger than the initial value.
[Relationship between damper set value and servo operation]
Small Value Setting
→
When you want to overshoot. Set so that hunting does not occur.
Large Value Setting
→
When you want to operate so that braking is not applied. However, it will feel like
the servo response has worsened.
(Note)
If used in the hunting state, not only will the current consumption increase, but the life of the servo
will also be shortened.
• Stretcher
The servo hold characteristic can be set. The torque which attempts to return the servo to the target
position when the current servo position has deviated from the target position can be adjusted.
This is used when stopping hunting, etc., but the holding characteristic changes as shown below.
[Relationship between stretcher and servo operation]
Small Value Setting
→
Servo holding force becomes weaker.
Large Value Setting
→
Servo holding force becomes stronger.
(Note)
When this parameter is large, the current consumption increases.
• Buzzer
When a servo is powered up without a transmitter signal, a buzzer sounds.
(When transmitter signal is lost, a buzzer sounds until the servo regains the signal. This is not unusual.
The transmitter has been turned OFF ahead of a servo power supply
→
The buzzer sound of about 1.25
Hz continues sounding as servo power supply end failure alarm.
(
Do not insert or remove the servo connector while the receiver power is ON.
A buzzer may
sound by incorrect recognition.
)
*
Buzzer sound is generated by vibrating the motor of a servo.
Since current is consumed and a servo generates heat, please do not operate the number more than
needed or do not continue sounding a buzzer for a long time.
WARNING
While S.BUS servo writes, you aren't
supposed to remove a connection of a
servo and turn off a power supply of a
transmitter.
■ Data of S.BUS servo is damaged and breaks down.
