Situation Possible cause Check/Treatment
and/or vibration from
actuator itself
Condition of load, condition actuator
installation, stiffness of device for the
actuator to be mounted to, etc.
Servo adjustment may improve the
situation.
Refer to [6.2 Servo Adjustment.]
It may be improved with setting to
Full Servo Mode if the case occurs
during deceleration and stop.
Refer to [5.2 Power-saving
[1] In the case of Positioner Mode
Situation Possible cause Check/Treatment
1) Acceleration/deceleration is set too
high.
2) The installation structure and/or the
installed load are easily affected by
acceleration/deceleration
1) Decrease the settings of
acceleration/deceleration.
[2] In the case of Pulse Train Control Mode
Situation Possible cause Check/Treatment
Vibrations of actuator or
load
Acceleration/deceleration is set too
high.
Decrease the setting of
acceleration/deceleration in the host
controller.
during acceleration
The host controller has no
acceleration/deceleration function or
does not have acceleration/deceleration
function from speed 0.
(Some positioning units have
acceleration/deceleration function but
cannot use the function from speed 0.
Note this when you select a positioning
