11.1.3 Troubleshooting of Alarm and Warning
When an error occurs in servodrive, an alarm display such as A.
A.9 appears on the panel operator. However, the display "A.--" is not an alarm. Refer to the following sec-
tions to identify the cause of an alarm and the action to be taken.
Contact your Yaskawa representative if the problem cannot be solved by the described corrective action.

Occurrence
The control power supply ranged from 30 VAC to
60 VAC.
The power supply was turned OFF while changing
the parameter setting.
The power supply was turned OFF while an alarm
was being written.
The number of times that parameters were written
exceeded the limit. For example, the parameter was
changed every scan through the host controller.
The SERVOPACK EEPROM and the related circuit
are faulty.
The control power supply ranged from 30 VAC to
60 VAC.
A SERVOPACK fault occurred.
The incorrect parameter was being loaded. (The
incorrect value was rejected as an error at the digital
operator.)
The SERVOPACK EEPROM and the related circuit
are faulty.
The SERVOPACK and servomotor capacities do not
correspond to each other.
Servomotor capacity / SERVOPACK capacity
or servomotor capacity / SERVOPACK capacity
The parameter that is written in the encoder is incor-
rect.
A SERVOPACK board fault occurred.
The setting of dividing ratio (Pn212) is not accept-
able (out of fixed increments), or exceeds the value
for the connected encoder resolution.
The SERVOPACK EEPROM and the related circuit
are faulty.
The connected serial encoder is not supported by
SGDM SERVOPACK.
A SERVOPACK board fault occurred.
and CPF
Cause
Correct the power supply, and set Fn005 to initial-
ize the parameter.
Set Fn005 to initialize the parameter and input the
parameter again.
Replace the SERVOPACK.
(Recheck the parameter writing method.)
Replace the SERVOPACK.
Correct the power supply.
Replace the SERVOPACK.
Set Fn005 to initialize the parameter.
Replace the SERVOPACK.
Select the proper combination of SERVOPACK

Replace the servomotor (encoder).
Replace the SERVOPACK.
Correct the setting of Pn212, and turn OFF the
control power and turn it ON again.
Replace the SERVOPACK.
Replace the servomotor with SGDM SERVO-
