Alarm Message List
Cause
The system error occurred in ARITH.
The system error occurred in ARITH offline.
The servo power supply was not turned on
for the job group axis which was to be oper-
ated.
The servo power supply was not turned on
for the job group axis which was to be oper-
ated.
The error occurred in the safe circuit signal
(I/O contactor unit). (Check the XCI01 cir-
cuit board duplication signal.)
The error occurred in the safe circuit signal
(I/O contactor unit). (Check the WRCA01
board duplication signal.)
A mistake was found in the paramete
related to servo control.
• The contactor of the contactor unit was not
turned ON at servo ON.
• While turning servo ON, the signal fro
the contactor was intercepted.
• The contactor signal was not intercepted
at servo OFF (at emergency stop).
• While turning servo OFF (at emergency
stop), the contactor signal was turned ON.
Reasons are as follows:
• Defective contactor unit
• Defective WRCA01 circuit board
• The brake relay signal unit was not turned
ON at servo ON.
• While turning servo ON, the brake relay
signal was intercepted.
• The brake relay signal was not intercepted
at servo OFF (at emergency stop).
• While turning servo OFF (at emergency
