10.3 Alarm Message List
10-25
1321
OVERCURRENT
(AMP)
Robot/Statio
[Axis Data]
One of the U,V,W wires of the motor dis-
played on the axis data was grounded at
least.
• Defective motor
• Ground fault of the motor, lead wire
• Defective WRCA01, WRCF01 circuit board
• Defective amplifier
• Overheating of amplifier
This alarm does not occur by turning off
the controlled power supply. But never fail
to turn on the servo power supply after
checking the motor grounding. There is a
possibility the servopack is damaged
when the servo turn-on and off is repeat-
ing ground fault status.
• Check the connection of the U,V,W,E
wires of motor again.
• Remove the U,V,W,E wires of the motor
from the terminal of the controller and
check the conduction of U-E, V-E, W-E.
If the wires are conducted, it's abnormal.
• In case an error is found by the above
check, remove the connector of the
motor side and check again. If the wires
are conducted, it is thought to be a
defective lead wire. Specify the error
point and replace the lead wire.
• If the error is not caused by the lead
wire, it is thought to be a defective motor.
• If the error occurs agai , replace the
WRCA01 and/or WRCF01 circuit board.
• Replace the amplifier, motor for the axis
where the error occurred.
1322
REGENERATIVE
TROUBLE
(CONVERTER)
[Bit Pattern]
Because the resurrection energy on
reducing the motor speed was too high, the
resurrection circuit board didn't work.
• The load installed on robot was too heavy.
• The primary side power supply voltag
was too high.(242V or more)
• Defective converter
• Defective WRCA01, WRCF01 circuit board
• Check the load again. Lower the teach-
ing speed of the fore and aft steps for
alarm occurrence step about 30% and
check the reoccurrence. If the alarm
doesn't reoccur, alter the load.
• Check the primary power supply(220V,
+10%).
• If the error occurs again, replace the
WRCA01, WRCF01 circuit board.
• Replace the converter for the axis where
the error occurred.
1323
INPUT POWER
OVER VOLTAGE
(CONV)
[Bit Pattern]
The primary side power supply voltage of
servopack was too high.(242V or more)
• Check the primary power supply(220V,
+10%).
• If the error occurs again, replace the
WRCA01 circuit board.
• Replace the converter for the axis where
the error occurred.
1324
TEMPERATURE
ERROR
(CONVERTER)
[Bit Pattern]
The temperature of servopack (converter
was too high.
• Check whether the ambient temperatur
is too high or not.
• Check the primary power supply(220V,
+10%).
• If the error occurs again, replace the
WRCA01 circuit board.
• Replace the converter for the axis where
the error occurred.
