Alarm Message List
Cause
The communication error occurred between
the encoder and the XFC01 circuit board.
• Improper wiring of encoder cables
• Noise from external devices
• Incorrect motor type
• Defective XFC01 circuit board
• Defective encoder
The tool file of CMOS memory was dam
aged.
The data stands for the file No.
The user coordinates file of CMOS memory
was damaged.
The data stands for the file No.
The servo monitor signal file of CMOS
memory was damaged.
The weaving condition file of CMOS mem-
ory was damaged.
The home position calibration file of CMOS
memory was damaged.
The specified point file of CMOS memory
was damaged.
The welder condition data file of CMOS
memory was damaged.
The data stands for the file No.
The arc start condition file of CMOS mem-
ory was damaged. The data stands for the
file No.

10.3 Alarm Message List
Remedy
• Check the encoder connection displayed
in the axis data.
• Check that there is no device generating
excessive noise.
• Check that the grounding of the control
panel is correct.
<Error in robot axis>
Check that the type of motor is same as
the one described in the manual. If the
type is not correct, replace it with the
correct motor.
<Error in external axis>
Check that the type of motor set by sys
tem configuration is same as actual
installed one. If the set data by system
configuration is correct, replace installed
motor with correct one. If set data by
system configuration is not correct, set
the correct system configuration.
• If the error occurs again, replace the
XFC01 circuit board.
Initialize the tool file in the maintenance
mode. Load the saved tool file in the
external memory unit and restore.
Initialize the user coordinates file in the
maintenance mode. Load the saved user
coordinates file in the external memory
unit and restore.
Initialize the servo monitor signal file in the
maintenance mode. Load the saved servo
monitor signal file in the external memory
unit and restore.
Initialize the weaving condition file in the
maintenance mode. Load the saved
weaving condition file in the external
memory unit and restore.
Reset the home position calibration (abso
lute data) after reset the alarm. Load the
home position calibration file (absolute
data) in the external memory unit and
restore.
Load the specified point file in the external
memory unit and restore.
Initialize the welder condition data file in
the maintenance mode. Load the saved
welder condition data file in the external
memory unit and restore.
Initialize the arc start condition file in the
maintenance mode. Load the saved arc
start condition file in the external memory
unit and restore.
