Alarm Number (1000 to 1999)
Alarm List-334
Module
failure(Regenerative
resistor)
(1)Disconnect the converter CN557 to check if there is no cable
disconnection.
(2)If disconnected, replace the regenerative resistor.
Module failure(converter) (1)Turn the power OFF then back ON.
(2)If the alarm occurs again, replace the converter.
EAXA21 board failure (1)Turn the power OFF then back ON.
(2)If the alarm occurs again, replace the EAXA21 board. Save the
CMOS.BIN before replacing the board to be safe.
other If the alarm occurs again, save the CMOS.BIN in maintenance mode,
and then contact your Yaskawa representative about occurrence
status (operating procedure).
1368 REGENERATIVE
TROUBLE
(CONVERTER)
Sub Code: Signifies the axis
in which the alarm occurred
Connection failure (1)Turn the power OFF then back ON.
(2)If the alarm occurs again, check the connection and inserting state
of the following cables and connectors.
・ EAXA21-CN507,510
・ EAXB21-CN531,532,533
・ Converter-CN557
・ Cable between the regenerative resistors
Module
failure(Regenerative
resistor)
Replace the regenerative resistor.
Module failure(converter) (1)Turn the power OFF then back ON.
(2)If the alarm occurs again, replace the converter.
EAXA21 board failure (1)Turn the power OFF then back ON.
(2)If the alarm occurs again, replace the EAXA21 board. Save the
CMOS.BIN before replacing the board to be safe.
Overloading Check that the load does not exceed the allowable limit.
other If the alarm occurs again, save the CMOS.BIN in maintenance mode,
and then contact your Yaskawa representative about occurrence
status (operating procedure).
1369 INPUT POWER OVER
VOLTAGE(CONV)
Sub Code: Signifies the
physical No. of converter in
which the alarm occurred
Voltage failure Modify the primary breaker voltage to the specified voltage 200V(+10
％～ 15％).
