7.2.3 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 6.3.1 [3], 6.3.2 [3] Servo
Adjustment.]
It may be improved with setting to Full
Servo Mode if the case occurs during
deceleration and stop.
[Refer to Chapter 5 Power-saving
Function]㩷
[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.
[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.
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.)
