Troubleshooting
Servomotor op-
eration is unsta-
ble.
Servomotor is
overheating.
There are un-
usual noises.
Vibration is oc-
curring at the
same frequency
as the applica-
ble power sup-
ply.
The Servomo-
tor operates
even when
speed com-
mand is for 0 V.
Symptom
The Servomotor power lines
or encoder lines are wired
incorrectly.
The bias function setting is
incorrect.
The polarity of the speed
command (REF) input is
wrong.
There are eccentricities or
looseness in the coupling
connecting the Servomotor
shaft and the mechanical
system, or there are load
torque fluctuations accord-
ing to how the pulley gears
are engaging.
Gain is wrong.
The ambient temperature is
too high.
Ventilation is obstructed.
There is an overload.
The correspondence be-
tween the Servo Driver and
the Servomotor is incorrect.
The machinery is vibrating.
Pn100 (Speed loop gain) is
insufficient.
Inductive noise is occurring.
The speed command volt-
age and the speed com-
mand input section are off-
set.
Probable cause
Check the Servomotor pow-
er line U, V, and W phases,
and the encoder line wiring.
---
Check the speed command
input wiring.
Check the machinery.
Try operating the Servomo-
tor without a load.
---
Check to be sure that the
ambient temperature around
the Servomotor is no higher
than 40°C.
Check to see whether any-
thing is blocking ventilation.
Check the torque command
value by means of monitor
mode (Un002).
Check the models.
Inspect the machinery to
see whether there are any
foreign objects in the mov-
able parts, or whether there
is any damage, deforma-
tion, or looseness.
---
Check to see whether the
Servo Driver control signal
lines are too long.
Check to see whether con-
trol signal lines and power
supply lines are too close to
each other.
Check the speed command
voltage.
Items to check
Correct the wiring.
Adjust Pn107 (bias rotation-
al speed) and Pn108 (bias
addition width).
Correct the wiring.
Adjust the machinery.
Use auto-tuning.
Adjust the gain manually.
Lower the ambient tempera-
ture to 40°C or less. (Use a
cooler or fan.)
Ensure adequate ventila-
tion.
Lighten the load.
Change to a larger capacity
Servomotor and Servo Driv-
er.
Combine models that corre-
spond correctly.
Fix any problems causing
vibration.
Use online auto-tuning.
Adjust the gain manually
(speed loop gain).
Shorten the control signal
lines.
Separate control signal lines
from power supply lines.
Use a low-impedance pow-
er supply for control signals.
Adjust the speed command
offset (Fn009 or Fn00A).
Use speed control mode
with position lock function.
(Control mode selection:
Pn000.1 = A)
