6-3 Troubleshooting
6-3-2 Error Diagnosis using the Operating Status
Problem Likely cause Items to check Countermeasures
Check whether the
Servomotor’s mounting screws
are loose. Tighten the mounting screws.
Check whether the axes are
misaligned in the mechanical
coupling system. Align the mechanical couplings.
There are problems with the
machinery’s installation.
Check whether the couplings
are unbalanced. Adjust the coupling’s balance.
There is a problem with the
bearings. Check for noise or vibration
around the bearings. Contact your OMRON
representative.
Noise is infiltrating the Control
I/O Cable because the cable
does not meet specifications. Check that the cable wires are
twisted-pair wires or shielded
twisted-pair wires that are at
least 0.08 mm
2
(28 AWG).
Use Control I/O Cable that meets
specifications.
Noise is infiltrating the Control
I/O Cable because the cable
is too long.
Check the length of the Control
I/O Cable. Shorten the Control I/O Cable to
less than 3 m.
Noise is infiltrating the cable
because the encoder cable
does not meet specifications.
Check that the cable wires are
twisted-pair wires or shielded
twisted-pair wires that are at
least 0.12 mm
2
(26 AWG).
Use encoder cable that meets
specifications.
Noise is infiltrating the
encoder cable because the
cable is too long. Check the length of the encoder
cable. Shorten the encoder cable to less
than 20 m.
Noise is infiltrating the signal
wires because the encoder
cable is damaged or the
sheath is cut.
Check the encoder cable for
cuts or other damage. Correct the encoder cable’s
pathway to prevent damage.
Too much noise is reaching
the encoder cable. Separate the encoder cables far
from high-current lines or check
whether the lines are too close.
Install the encoder cable where it
won’t be subjected to surges.
The FG’s potential is
fluctuating due to devices
near the Servomotor, such as
welding machines.
Check for ground problems
(loss of ground or incomplete
ground) at equipment such as
welding machines near the
Servomotor.
Ground the equipment properly
and prevent currents flowing to
the Encoder FG.
Errors are being caused by
excessive vibration or shock
on the encoder.
There are problems with
mechanical vibration or motor
installation (such as the
mounting surface, attachment,
or axial offset).
Reduce the mechanical vibration
or correct the Servomotor’s
installation.
The Servomotor is
producing unusual
noises or the machinery
is vibrating.
The filter setting is not
suitable. Check the setting on the
command filter setting rotary
switch (FIL).
Increase the value set on the
command filter setting rotary
switch (FIL).
