Assumed cause
Correction
Prevention
• Power supply voltage is insuffi-
cient at power ON, or rising
slowly.
• Power supply voltage fluctu-
ated at power ON.
• L1, L2, and L3 terminals are
not connected or discon-
nected.
• N1 and N2 terminals are
opened.
Cut off the main circuit power sup-
ply immediately and check
whether charge lamp is turned
ON/OFF.
If the charge lamp is turned OFF,
remove the wiring and make the
following check.
• Check whether there is an
abnormality in the appearance
of the Servo Drive, and that the
wiring is properly done.
• Check that the resistance value
and the power of the External
Regeneration Resistor is cor-
rect.
• Wait until the voltage between P
and N1 goes to less than 1 V to
check the resistance value
between P and N1. (If it is less
than 10 k
Ω
, replace the Servo
Drive.)
• Wait until the voltage get stable
to check the resistance value
between B2 and N1. (If it is less
than 100 k
Ω
, replace the Servo
Drive.)
• Check whether fluctuation in the
power supply voltage or power
supply occurs or not. (Make sure
that an instantaneous power
drop does not occur, and that
the power rise time is 500 ms or
shorter.)
If the charge lamp is turned ON,
check whether fluctuation in the
power supply voltage or power
supply occurs or not. (Make sure
that an instantaneous power drop
does not occur, and that the power
rise time is 500 ms or shorter.)
• If you are using the External
Regeneration Resistor, make
sure that an appropriate resis-
tance value is set and that it is a
resistor for the electric power.
• Increase the power supply
capacity to improve the power
environment.
• Separate the Servo Drive and
cables from the noise source, or
install other devices separately
with the power line of the Servo
Drive so that the surge voltage
that is too large is not imposed.
• Power rise time must be 500 ms
or shorter.
• Check that the wiring for the fol-
lowing terminals is properly
done: L1, L2, L3, N1, N2, N3,
B1, B2, B3, and P.
Servo Drive failure
If this event occurs again after you
performed all corrections shown
above, replace the Servo Drive.
