Troubleshooting
Section 11-1
42 The positioning
completed sig-
nal is not output
or is delayed.
(The next opera-
tion cannot be
started.) The in-position range set in
the MC Unit parameters is
too narrow, and the axis is
not in the in-position range.
(If it is not in the in-position
range, the next operation
cannot be started because
the preceding operation is
not completed.) Increase the in-position range
set in the MC Unit parameters.
43 The Servo Driver gain is
too low. Adjust the Servo Driver gain
and increase the MC Unit posi-
tion loop gain.
44 The axis is not in the in-
position range due to exter-
nal pressure applied when
positioning is stopped. With the Support Tool, monitor
the error counter and check
whether the axis is in the in-
position range. If positioning is stopped outside
of the in-position range due to
external pressure (occurs in
pressing application, etc.),
Increase the in-position range in
the Motion program.
45 There are
unusual noises. The machinery is vibrating. Check for foreign objects in the
machinery’s moving parts, and
inspect for damage, deforma-
tion, and looseness.
Make any necessary repairs.
46 The speed loop gain is
insufficient. (The gain is too
high.) Perform auto-tuning.
Manually adjust (decrease) the
gain.
47 The wrong Servomotor is
selected (so it cannot be
adjusted). Check the torque and inertia
ratio and select another Servo-
motor. Change to a suitable Servomo-
tor.
48 There is eccentricity in the
couplings connecting the
Servomotor axis and the
mechanical system. Adjust the mounting of the Ser-
vomotor and machinery.
49 Vibration is
occurring at the
same frequency
as the applica-
tion frequency. Inductive noise is being
generated. • Check whether the Servo
Driver control signal lines are
too long.
• Check whether the control sig-
nal lines and power lines are
bundled together.
• Shorten the control signal
lines.
• Separate the control signal
lines and the power lines.
• Use a low-impedance power
supply for the control signal
lines.
50 The control signals are not
properly grounded. • Check whether the control sig-
nal shield is properly grounded
at the Servo Driver.
• Check whether the control sig-
nal lines are in contact with the
ground.
Correct the wiring.
