Alarm Message List
Cause
The communication between the XCP01
circ board and the WRCA01 circuit board
was abnormal.
• The cable between the XCP01 circuit
board and WRCA01 circuit board was
defective.
• The connection of the terminal connector
was incomplete.
• Defective XCP01 circuit board
• Defective WRCA01 circuit board
The communication between the XCP01
circ board and the WRCA01 circuit board
was abnormal.
• The cable between the XCP01 circuit
board and WRCA01 circuit board was
defective.
• The connection of the terminal connector
was incomplete.
• Defective XCP01 circuit board
• Defective WRCA01 circuit board
The communication between WRCA01 cir-
cuit board and the contactor unit (for I/O,
robot, external axis) was abnormal.
The error occurred on check of interior con-
trol for the WRCA circuit board.
• The system included the external axis, but
the external axis circuit board (WRCF0
board) was not installed.
• The system did not include the external
axis, but the system with external axis was
set.
• Defective WRCF01 circuit board
• Defective WRCA01 circuit board

Remedy
• Check the connection of communication
cable for servopack.
(XCP01(CN05 - WRCA(#*)(CN10 cable,
WRCA(CN10(#*) - WRCA(CN10(#*
cable
• Replace the communication cable for
servopack.
• Check the connection of the terminal
connector (WRCA( CN10(#*)).
• Replace the terminal connector.
• Replace the XCP01 circuit board,
WRCA01 circuit board.
• Check the connection of communication
cable for servopack.
(XCP01(CN05 - WRCA(#*)(CN10 cable,
WRCA(CN10(#*) - WRCA(CN10(#*
cable
• Replace the communication cable for
servopack.
• Check the connection of the terminal
connector (WRCA( CN10(#*)).
• Replace the terminal connector.
• Replace the XCP01 circuit board,
WRCA01 circuit board.
• If the error occurs again, contact your
YASKAWA representative.
• Check the connection for communication
cable between the WRCA01 circuit
board and contactor unit.
(WRCA01(#*)(CN20 - XIU01(CN21
cable
• Replace the WRCA01 circuit board.
• Replace the contactor unit.
• If the error occurs again, contact your
YASKAWA representative.
Needs investigation. Consult a YASKAWA
representative.
<The system with external axis>
• Check the installation of the external axis
circuit board(WRCF01 board).
• If the WRCF01 circuit board is installed,
replace it.
<The system without external axis>
• Check the system is not included exter-
nal axis.
• Execute the system configuration again
on system without external axis.
