Generation of abnormal noise or vibration
Situation
Possible cause
Confirmation/countermeasure
Generation of abnormal
noise or vibration from
the actuator itself.
Possible causes of abnormal noise or
vibration vary, including load
condition, actuator mounting
condition, rigidity of the device on
which the actuator is mounted, etc.
In some cases, servo adjustment can
improve the situation.
[Refer to Startup Section Chapter 6, 6.1
Parameter/Servo gain adjustment (page
B6-61)]
Vibration of load.
1) Acceleration/deceleration setting is
too high.
2) Mounting structure or load
susceptible to
acceleration/deceleration is
mounted.
1) Lower the acceleration/deceleration
setting.
2) Review the mounting structure or load.
Communication failure
Situation
Possible cause
Confirmation/countermeasure
Unable to connect to
host device.
1) Communication speed is
mismatched.
2) Machine number (station number)
setting is duplicated with another
device, or value is outside range.
3) Faulty wiring or disconnection,
etc., of communication cables.
1) Match the setting with the host device.
[Refer to host device instruction manual]
2) Revise machine number (station
number) setting.
Machine number (station number) differs
depending on the communication
method. Refer to field network
specification address map and host
device instruction manual for details.
3) Review wiring.
Confirm that the terminal resistor is
connected to the network terminal at the
correct value.
For DeviceNet specification, confirm that
communication power is supplied
correctly.
