12 Troubleshooting and Maintenance
12 - 32
G5-series Linear Motors/Servo Drives With Built-in EtherCAT Communications
The Linear Motor or the load
generates abnormal noise or
vibration.
(Continued from previous
page)
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.
The Position Loop Gain 1
(3100 hex) is too large.
Review the setting of object
3100 hex.
Use the CX-Drive or the
analog monitor to measure
the response and adjust the
gain.
The Speed Loop Gain 1
(3101 hex) and the Speed
Loop Integral Time Constant
1 (3102 hex) are balanced
incorrectly.
Review the set values of
objects 3101 hex and
3102 hex.
Noise is entering into the
control I/O signal cable
because the cable does not
meet specifications.
Check to see if the cable is a
twisted-pair cable or shielded
twisted-pair cable with core
wires that are at least
0.08 mm
2
.
Use a control I/O signal cable
that meets specifications.
Noise is entering into the
control I/O signal cable
because the cable is longer
than the specified length.
Check the length of the
control I/O signal cable.
Shorten the control I/O signal
cable to 3 m or less.
Noise is entering into the
external encoder cable
because the cable does not
meet specifications.
Check to see if it is a
shielded twisted-pair cable
with core wires that are at
least 0.12 mm
2
.
Use a control I/O signal cable
that meets specifications.
Noise is entering into the
external encoder cable
because the cable is longer
than the specified length.
Check the length of the
external encoder cable.
Shorten the external encoder
cable to less than 50 m.
Noise is entering into the
signal lines because the
external encoder cable is
stuck or the sheath is
damaged.
Check the external encoder
cable for damage.
Correct the external encoder
cable’s pathway.
Excessive noise on external
encoder cable.
Check to see if the external
encoder cable is bound
together with or too close to
high-current lines.
Install the external encoder
cable where it won’t be
subjected to surges.
The FG’s potential is
fluctuating due to devices
near the Linear Motor, such
as welding machines.
Check for ground problems
(loss of ground or incomplete
ground) at equipment such
as welding machines near
the Linear Motor.
Ground the equipment
properly and prevent current
from flowing to the external
encoder FG.
Errors are being caused by
excessive vibration or shock
on the external encoder.
There are problems with
mechanical vibration or
motor installation (such as
the precision of the mounting
surface or attachment).
Reduce the mechanical
vibration or correct the Linear
Motor’s installation.
