STRE (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.
BSTM (Boost/-N/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).
BOST (Boost)
The minimum current applied to the internal motor when starting the servo
can be set. Since a small travel does not start the motor, it essentially feels
like the dead band was expanded. The motor can be immediately started
by adjusting the minimum current which can start the motor.
[Relationship between boost set value and servo operation]
Small - Motor reacts to a minute current and operation becomes smooth.
Large - Initial response improves and output torque increases. However, if
the torque is too large, operation will become rough.
CHAN (Channel)
This is the S.BUS system channel assigned to the servo. When connected
to the receiver S.BUS2 connector as an S.BUS system, the channel used
by the transmitter is assigned. When the normal receiver channel is used,
channel setting is unnecessary.
NEUT (Neutral)
The neutral position can be changed. When the neutral offset is large val-
ue, the servo's range of travel is restricted on one side.
EPAL (Travel-left side)
The maximum left travels centered about the neutral position can be set
independently.
EPAR (Travel-right side)
The maximum right travels centered about the neutral position can be set
independently.
REVE (Reverse)
The direction in which the servo rotates can be changed.
