Alarm List Alarm Number (4000 to 4999)
Alarm List-709
GND wiring failure (1)Turn the power OFF then back ON.
(2) If the alarm repeats, check the voltage of the primary power and
GND. If the voltage amount on each RST varies more than 100V,
review the GND setting.
Module failure (motor) (1)Reset the alarm.
(2)If the alarm occurs again, replace the motor.
Module failure (amplifier) (1)Reset the alarm.
(2)If the alarm occurs again, replace the amplifier.
Module failure (contactor) (1)Reset the alarm.
(2)If the alarm occurs again, replace the contactor.
EAXA21 board failure (1)Reset the alarm.
(2)If the alarm occurs again, replace the EAXA21 board. Save the
CMOS.BIN before replacing the board to be safe.
YPU unit failure (1)Reset the alarm.
(2)If the alarm occurs again, replace the YSF21 board. Save the
CMOS.BIN before replacing the YPU unit 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).
