S.BUS Servo
1
On the setting screen of each function, if you tap the item to be set, "[-] [Reset] [+]" is dis-
played at the bottom of the screen, tap the [-] [+] on the panel set. Tap[Reset] to return to
the initial value. There are items with no
[reset]. In the case of selection type, data
is switched by tapping an item.
ID
Displays the ID of the servo where param-
eters are to be read. It cannot be changed.
Dead band
The dead band angle at stopping can be
specified.
[Relationship between dead band set val-
ue and servo operation]
Small - Dead band angle is small and a small signal change immediately operates the ser-
vo.
Large - Dead band angle is large, and the servo does not operate at small signal changes.
(Note)
If the dead band angle is too small, the servo will work continuously, and the current consumption will in-
crease, and the life of the servo will be shortened.
Damper
The characteristic when the servo is stopped can be set.
When smaller than the standard value, the characteristic becomes an overshoot character-
istic. If the value is larger than the standard value, the brake is applied before the stop posi-
tion.
Especially when a large load is applied, overshoot, etc. are suppressed by inertia and hunt-
ing may occur, depending on the conditions. If hunting (phenomena which causes 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. Fixed 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 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.
Smoother
This function makes the servo operation smooth. Set it according to your taste. Normally
set it to "ACT". Set it to "INH when you want an exceptionally quick operation. When the
smoother function was set to "ACT" and the servo has operated the distance up to the tar-
get position is changed in steps so movement is smooth.
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.
