bleshooting Using the Operation State
The motor is overheating.
The ambient temperature is
too high.
Check to see if the ambient
temperature around the
motor is over 40°C.
•
Lower the ambient
temperature around the
motor to 40°C or less. (Use
a fan or air conditioner.)
•
Lower the load ratio.
The heat radiation condition
for the motor is inappropriate.
•
Check to see if the
specified radiation
conditions are observed.
•
For a motor with a brake,
check the load ratio.
•
Improve the radiation
conditions.
•
Reduce the load.
•
Improve ventilation.
The motor is overloaded.
Measure the force on the
analog monitor on the front
panel or from the CX-Drive.
•
Decrease the acceleration
and deceleration rates.
•
Lower the speed and
check the load.
The motor vibrates during
operation.
The machine position is
misaligned.
There is an error in the
coupling of the Liner Motor
and the mechanical system.
Check to see if the coupling
of the Linear Motor and the
machine is misaligned.
•
Tighten the coupling again.
The host controller gave a
deceleration stop command.
Check the control ladder
program in the host
controller.
Review the control in the
host controller.
The motor does not stop or is
hard to stop even if the servo
is turned OFF while the
motor is operating.
The load mass is too large.
•
Check the load mass.
•
Check the motor speed.
•
The dynamic brake
resistance is disconnected.
•
Review the load mass.
•
Replace the motor and
Servo Drive with proper
ones.
The dynamic brake is
disabled.
Check if the dynamic brake is
disabled or broken.
•
Enable the dynamic brake,
if it is disabled.
•
Replace the brake if it is
broken or if the resistor is
disconnected.
The Linear Motor or the load
generates abnormal noise or
vibration.
Vibration occurs due to
improper mechanical
installation.
Check to see if the Linear
Motor’s mounting screws are
loose.
Retighten the mounting
screws.
Check the load for
eccentricity.
Eliminate the eccentricity.
Check to see if the coupling
with the load is unbalanced.
Balance the operation.
Vibration occurs due to low
mechanical rigidity.
Check to see if the vibration
frequency is 100 Hz or lower.
If the frequency is 100 Hz or
lower, set the correct
damping frequency for the
damping filter to eliminate
the vibration.
Vibration occurs due to
machine resonance.
Check to see if the
resonance frequency is high
or low.
If the resonance frequency is
high, set the adaptive filter to
eliminate the resonance.
Alternatively, measure the
resonance frequency and set
Notch Filter 1 and 2.
There is a problem with the
linear guides.
Check for noise or vibration
around the linear guides.
Check to see if the linear
guides are mounted properly,
and adjust them if necessary.
The gain is wrong.
–
Check if manual tuning can
achieve proper adjustment.
The Speed Feedback Filter
Time Constant 1 (3103 hex)
is wrong.
Check the set value of object
3103 hex. Normally set “0.”
Return the setting to the
default value of 0.
Alternatively, set a large
value and operate the motor.
