10.3 Alarm Message List
10-36
4303 CONVERTER
READY SIGNAL
ERROR
[Bit Pattern] • There was no response (servo ready sig
nal) of charge completion from convertor at
servo ON.
• While turning servo ON, the servo ready
signal was intercepted.
• The servo ready signal was not inter-
cepted at servo OFF (at emergency stop).
• While turning servo OFF (at emergency
stop), the servo ready signal was turned
ON.
Reasons are as follows:
• Primary side power supply voltage was too
low.
• Because the power supply cable of pri-
mary side was too fine or its cable was too
long, the voltage drop occurred at servo
ON.
• Defective WRCA01,WRCF01 circuit boar
• Defective converte
• Reset the alarm and turn servo ON
again.
• Check the primary power supply voltage
(220V+10%).
• If the error occurs again, replace the
WRCA01 circuit board, the converter.
4304 CONVERTER INPUT
POWER ERROR
[Bit Pattern] • There was no response (ready 1 signal) of
primary power supply input from convertor
at servo ON.
• While turning servo ON, the ready 1 signal
was intercepted.
• The ready 1 signal was not intercepted at
servo OFF (at emergency stop).
• While turning servo OFF (at emergency
stop), the ready 1 signal was turned ON.
Reasons are as follows:
• Mistaken wiring of connection for primary
side power supply.
• The drop of primary side power supply
(less than170V).
• Because the power supply cable of pri-
mary side was too fine or its cable was too
long, the voltage drop occurred at servo
ON.
• Defective WRCA01,WRCF01 circuit boar
• Defective converte
• Check the connection for primary side
wiring R,S,T, wire.
• Check that the power supply voltage is
more than 170V.
• If the error occurs again, replace the
WRCA01 circuit board, WRCF01 circuit
board, the converter.
