Setup item
ID
Displays the ID of the servo whose parameters are to be read. It cannot
be changed.
SMOT (Smoother)
This function makes servo operation smooth. Set it according to your
taste. Normally set it to "ACT". Set it to "INH" when you want especially
quick operation. When the smoother function is set to "ACT" and the servo
is operated, the distance up to the target position is changed in steps so
movement is smooth.
DEAD (Dead band)
The dead band angle at stopping can be specifi ed.
[Relationship between dead band set value and servo operation]
Small - Dead band angle is small and the servo is immediately operated
by a small signal change.
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 operate continu-
ously and the current consumption will increase and the life of the servo
will be shortened.
DAMP (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, depend-
ing 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
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.
