34.1 SSCNET
receive data
error
(1) The SSCNET III cable
was disconnected.
Check the SSCNET
III cable connection.
It is disconnected.
Turn off the control
circuit power supply
of the servo
amplifier, and then
connect the
SSCNET III cable.
[B]
[WB]
It is connected.
Check (2).
(2) The surface at the end
of SSCNET III cable
got dirty.
Wipe off the dirt from
the cable tip, and
then check the
repeatability.
It is not repeatable.
Take measure to
keep the cable tip
clean.
It is repeatable.
Check (3).
(3) The SSCNET III cable
is broken or severed.
Check if the SSCNET
III cable is
malfunctioning.
It has a failure.
Replace the
SSCNET III cable.
It has no failure.
Check (4).
(4) A vinyl tape is stacked
to the SSCNET III
cable. Or a wire
insulator containing
migrating plasticizer is
adhered to the cable.
Check if a vinyl tape
is used. Check if the
cable is contacting
with other cables.
It is used. They are
in contact.
Take
countermeasures
against its cause.
It is not used. They
are not in contact.
Check (5).
(5) The servo amplifier is
malfunctioning.
Replace the servo
amplifier, and then
check the
repeatability.
It is not repeatable.
Replace the servo
amplifier.
It is repeatable.
Check (6).
(6) The previous or next
axis servo amplifier of
the alarm occurred is
malfunctioning.
Replace the previous
and next servo
amplifier of the axis
alarm occurred, and
then check the
repeatability.
It is not repeatable.
Replace the servo
amplifier.
It is repeatable.
Check (7).
(7) The controller is
malfunctioning.
Replace the
controller, and then
check the
repeatability.
It is not repeatable.
Replace the
controller.
It is repeatable.
Check (8).
(8) Something near the
device caused it.
Check the noise,
ambient temperature,
etc.
It has a failure.
Take
countermeasures
against its cause.
