Error and Maintenance
The motor is
producing unusual
noises or the
machine is
vibrating.
(Continued from
previous page) The machine and the motor
are resonating. Check whether the machine is
resonating.
• Readjust the torque
command filter time
constant.
• If there is resonance, set
the Notch Filter 1
Frequency (Pn201), Notch
Filter 1 Width (Pn202), and
Notch Filter 1 Depth
(Pn203).
Vibration is
occurring at the
same frequency as
the power supply. Inductive noise is occurring. Check whether the driver control
signal lines are too long.
Shorten the control signal
lines.
Check whether the control signal
lines and power supply lines are not
bound together.
• Separate control signal
lines from power supply
lines.
• Use a low-impedance
power supply for control
signals.
The position is
misaligned.
(Position
misalignment
occurs without an
alarm being
output.) There is an error in the
coupling of the mechanical
system and the Servomotor. Check whether the coupling of the
mechanical system and the
Servomotor is misaligned. Correct the coupling between
the mechanical system and
the Servomotor.
Noise is entering the error
counter reset (ECRST). Check whether the control signal
lines and power supply lines are not
bound together. Separate the control signal
lines from the power lines or
take other measures against
noise.
The gain is wrong.
−
Perform manual tuning.
The load inertia is large.
Inspect the following.
• Is the load too large?
• Is the motor rotation speed too
high?
• Adjust the gain.
• Review the load
conditions, and replace the
Servomotor and Servo
Drive with appropriate
models.
