s
ing the Oper
ation State
The Linear Motor or the
load generates abnormal
noise or vibration.
Vibration occurs due to
improper mechanical
installation.
Check to see if the Linear
Motor's mounting screws are
loose.
Retighten the mounting screws.
Check the load for eccentricity.
Eliminate the eccentricity.
Check to see if the coupling
with the load is unbalanced.
Balance the operation.
Vibration occurs due to low
mechanical rigidity.
Check to see if the vibration
frequency is 100 Hz or lower.
If the frequency is 100 Hz or
lower, set the correct damping
frequency for the damping filter
to eliminate the vibration.
Vibration occurs due to
machine resonance.
Check to see if the resonance
frequency is high or low.
If the resonance frequency is
high, set the adaptive filter to
eliminate the resonance.
Alternatively, measure the
resonance frequency and set
Notch Filter 1 and 2.
There is a problem with the
linear guides.
Check for noise or vibration
around the linear guides.
Check to see if the linear
guides are mounted properly,
and adjust them if necessary.
The gain is wrong.
Check if manual tuning can
achieve proper adjustment.
The Speed Feedback Filter
Time Constant 1 (3103 hex)
is wrong.
Check the set value of object
3103 hex. Normally set 0.
Return the setting to the default
value of 0. Alternatively, set a
large value and operate the
motor.
The Force Command Filter
Time Constant 1 (3104 hex)
does not match the load.
Review the set value of object
3104 hex.
Set a larger value for object
3104 hex to eliminate the
vibration.
