Alarm Number (1000 to 1999)
Alarm List-332
1365 GROUND FAULT Sub Code: Signifies the axis
in which the alarm occurred.
(If the alarm occurred at an
axis which is driven by a
common converter, all the
subject axes are indicated.)
Connection failure (1)Turn the power OFF then back ON.
(2)If the alarm occurs again, check the connection and inserting state
of the following cables and connectors.
・ EAXA21-CN507,510
・ Converter CN551,553,555
・ EX1SV (External axis SERVO PACK)-CN592
・ YPU unit-CN604
Connection failure (1)Turn the power OFF then back ON.
(2)If the alarm occurs again, replace the following cables.
Check the axis in which earth fault occurs in the alarm history screen.
If both robot axes and external axes use the same type converter, the
earth fault may occur on the external axis not the robot axis. (There is
also a possibility that it is stained by water)
(1) External axis cables (Power wire)
(2) Traveling axis cable (Power wire)
(3) Power supply cable (Robot axis, external axis) (Power wire)
(4) Internal cables (Robot axis, external axis) (Power wire)
Module
failure(Regenerative
resistor)
Check if there is no ground fault in the regeneration resistors.
GND wiring failure (1)Turn the power OFF then back ON.
(2) If the alarm repeats, check the voltage of the primary power and
GND. If the voltage amount on each RST varies more than 100V,
review the GND setting.
Module failure(motor) (1)Turn the power OFF then back ON.
(2)If the alarm occurs again, replace the motor.
Module failure(amplifier) (1)Turn the power OFF then back ON.
(2)If the alarm occurs again, replace the amplifier.
Module failure(contactor) (1)Turn the power OFF then back ON.
(2)If the alarm occurs again, replace the contactor.
EAXA21 board failure (1)Turn the power OFF then back ON.
(2)If the alarm occurs again, replace the EAXA21 board. Save the
CMOS.BIN before replacing the board to be safe.
