• Boost ON/OFF
OFF : The boost turns ON at the time of lower-demand operation. (In most cases)
ON : The boost is always ON. (When quick operation is needed)
• 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 suppushed 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 → When you want to overshoot. Set so that hunting does not occur.
Large → When you want to operate so that braking is not applied. However, it will feel like the servo
response has slowed down.
(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 → Servo holding force becomes weaker.
Large → Servo holding force becomes stronger.
(Note) When this parameter is large, the current consumption increases.
• Buzzer
When the power supply of a servo is interrupted or a loss of signal from the transmitter, the buzzer sound
of about 2.5Hz continues sounding from a servo.
(Even when the signal output of a transmitter is lost, a buzzer becomes until the signal of a servo is
outputted normally.)
The transmitter has been turned OFF ahead of a servo power supply → The buzzer sound of about 1.25
Hz continues sounding to show that the servo power supply is still turned on.
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 a lot of current is consumed and a servo generates heat during buzzer sounds, please do not
operate the feature more than needed or do not continue sounding a buzzer for a long time.
