the same
frequency as
the
commercial
frequency
Problem
The in-position width
is not achieved in a
standstill state due to
an external force.
Mechanical vibration
Insufficient adjustment
of the Servo Drive gain
(high gain)
Wrong motor selection
(adjustment not
possible)
Misalignment of the
coupling that connects
the motor shaft and
machine
Generation of
inductive noise
Grounding of the
control signal line is
not correct.
Twisted-pair and
shielded cable is not
used for connection
between the PCU and
drive.
Probable cause
Check the error counter
with the Servo Drive
monitor function to
check if the present
position is inside the in-
position width.
Check the moving parts
of the machine for
intrusion of foreign
matter, damage,
deformation and
loosening.
Select a motor again
(check the torque and
inertia ratio).
Check if the drive's
control signal line is too
long.
Check if the control
signal line is bundled
with the power supply
line.
Check if the shield of the
control signal line is
grounded correctly on
the drive side (wiring
check).
Check if the control
signal line is contacting
the grounding wire.
Check if the pulse signal
line uses a twisted-pair
cable and if the entire
cable is shielded.
Item to check
−
−
In situations where you
stop the axis in such a
way that a position
inside the in-position
width is not achieved,
such as in push control,
you can use the error
counter reset output to
forcibly achieve the in-
position width. Since the
origin will be
unconfirmed, however,
you must confirm the
origin again by Origin
Search or present
position preset.
Correct the problem
location, if any.
Perform auto-tuning.
Manually adjust (lower)
the gain.
Change to an optimal
motor.
Adjust the motor and
machine installation.
Shorten the control
signal line.
Isolate the control signal
line from the power
supply line.
Make sure that the
control signals are
received from a low-
impedance power
supply.
Wire correctly.
Use a twisted-pair shield
cable and wire it
according to the wiring
example.
