10.3 Alarm Message List
10-27
1331 CURRENT FEED-
BACK ERROR
(U PHASE)
Robot/Statio
[Axis Data]
When the phase balance of the motor cur
rent was automatically adjusted, the read U
phase current value was abnormal.
• Defective WRCA01 circuit board
• Defective amplifier
Turn the power off then back on. If the
phenomenon occurs again after repeating
this operation several times, replace the
WRCA01 circuit board, amplifier for the
axis where the error occurred.
1332 CURRENT FEED-
BACK ERROR
(V PHASE)
Robot/Statio
[Axis Data]
When the phase balance of the motor cur
rent was automatically adjusted, the read V
phase current value was abnormal.
• Defective WRCA01 circuit board
• Defective amplifier
Turn the power off then back on. If the
phenomenon occurs again after repeating
this operation several times, replace the
WRCA01 circuit board, amplifier for axis
the error occurred.
1335 ENCODER NOT
RESET
Robot/Statio
[Axis Data]
Reset was not completed though encoder
backup error reset was requested. It may
be possible that the battery is not connected
with the encoder.
• Connect the battery with the encoder.
Contact your YASKAWA representative
because the breakdown of the encoder
is thought when the alarm occurs again
even if the battery is connected.

tactor unit and the XFC01 circuit boar
• Disconnected cable between the I/O con-
tactor unit and the XCI01 circuit board
• Defective I/O contactor unit
• Defective XFC01 circuit board
• Check the cable connection between the
I/O contactor unit and the XFC01 circuit
board.
• Check the cable connection between the
I/O contactor unit and the XCI01 circuit
board.
• Replace the I/O contactor unit and the
XFC01 circuit board.
• If the error occurs again, contact you
YASKAWA representative.
1340 BROKEN SPEE
MONITOR LINE
The speed monitoring command cable is
disconnected.
• Check the connection cable of the I/O
contactor unit.

I/O contactor unit and the XFC01 circuit
board.
• Check the cable connection between the
I/O contactor unit and the XCI01 circuit
board.
• Replace the I/O contactor unit and the
XFC01 circuit board.
• If the error occurs again, contact you
