9.2.3 Generation of noise and/or vibration
Situation Possible cause Check/Treatment
Generation of noise
and/or vibration from
actuator itself
Noise and vibration are generated
by many causes including the
status of load, the installation of the
actuator, and the rigidity of the unit
on which the actuator is installed.
Servo adjustment may improve the
situation.
[Refer to 8.3 Servo Adjustment.]
[In the case of Positioner Mode]
Situation Possible cause Check/Treatment
Vibrations of load 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.
Set S-shape
acceleration/deceleration.
[Refer to 8.2 [42] S-motion rate.]
2) Use the vibration suppress control
function.
[Refer to Chapter 5.]
[In the case of Pulse String 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 or set S-shape
acceleration/deceleration.
Generation of noise
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 unit.)
