8.2.3 Generation of noise and/or vibration
Situation Possible cause Check/Treatment
Generation of noise
and/or vibration from
actuator itself
Noise and vibration are generated by
many causes including the status of
load, the installation of the actuator,
and the rigidity of the unit on which the
actuator is installed.
Servo adjustment may improve the
situation.
[Refer to 7.3 Servo Adjustment.]
Vibrations of load 1) Acceleration/deceleration is set too
high.
2) The installation structure and/or the
installed load are easily affected by
acceleration/deceleration.
1) Decrease the settings of
acceleration/deceleration.
8.2.4 Impossible Communication
Situation Possible cause Check/Treatment
Not connectable with
host unit
1) Communication rates do not match.
2) The station number (node address)
is set to be duplicate with that of
another unit or out of the range.
3) Poor wiring or disconnection of
communication cable
1) Set the communication rate to
match that of the host machine.
[Refer to the Instruction Manual
of the host unit.]
2) Correct the station number
(node address) setting.
Station number (node address)
vary depending on
communication modes. Refer to
3.4 Fieldbus Type Address Map
and the instruction manuals for
the host devices for the details.
3) Check if the wiring is conducted
correctly.
Confirm that the connectors are
joined solidly, and the cables
inserted to the connectors are
surely fixed.
Check if termination resistances
are connected to network
terminals with correct values.
Check if the communication
power supply is established
properly for DeviceNet Type.
