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 be-
come rough.
NEUT (Neutral)
The neutral position can be changed. When the neutral offset is large value, 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.
SR-M (SR mode)
It is a dedicated setting to change SR mode. See "SR mode setting" (Page 79).It is not
changed in "WRITE" (page 78) of MODE of the setting item.
