AL-1323 (INPUT POWER OVERVOLTAGE (CONV))
An alarm
occurs.
Excessive input-voltage of SERVOPACK may damage the regenerative resistor.
Before checking the wiring connections, turn
OFF the control power supply.
Use a tester to confirm that all the LEDs on
the SERVOPACK and converter are unlit and
that no charged electricity remains.
(It may take a few minutes until all the
electricity is discharged.)
Does the alarm occur
when the servo is OFF?
YesNo
Remove connector CN30 on the
WRCA01 circuit board and re-insert it.
(See Fig. 8.)
Alarm?
Yes No
Remove connector CN1 on the
converter and re-insert it. (See Fig. 8.)
Alarm?
Yes No
Continue normal
operation.
Replace the converter.
Alarm?
NoYes
Change the breaker's primary voltage
to the specified voltage.

Is the converter's primary voltage
200 V (+10% to 15%)? (See Fig. 9.)
Yes No
Continue normal
operation.
Replace the converter.
Alarm?
NoYes
Contact your Yaskawa
representative.
Continue normal
operation.
Replace the WRCA01 circuit board.

Fig. 9
Measure the voltage between L1 and L2, L1 and L3, and L2 and L3
to confirm the voltage is less than 200V + 10%.

(Measure the
resistance.)
