Cause Investigative Actions
–
Refer to the catalog of the con-
nected feedback option module or
the manual of the SERVOPACK.
–
–
Check the connection between the
SERVOPACK and the command
option module.
−
−
Measure the time lag between the
/HWBB1 and /HWBB2 signals.
−
−
Check the power supply wiring.
Measure the voltage at each phase
of the three-phase power supply.
Check the power supply and the
parameter setting.
−
Check the connector contact.

8.1 Troubleshooting
Corrective Actions
Replace the feedback option mod-
ule.
Connect a compatible feedback
option module.
Execute Fn014 (Resetting configu-
ration error of option module) with
the digital operator or SigmaWin+
and turn the power supply OFF and
then ON again.
Turn the power supply OFF and
then ON again. If the alarm occurs
again, restart communications pro-
cessing from the host controller.
Correctly connect the command
option module.
Replace the command option mod-
ule.
Replace the SERVOPACK.
The host controller output signal
circuits or devices for /HWBB1 and
/HWBB2 or the SERVOPACK
input signal circuits may be faulty.
Alternatively, the input signal
cables may be disconnected. Repair
or replace them.
Input a servo ON command when
the linear servomotor is stopped.
Check that the linear scale is con-
nected correctly and input a sensor
ON command when the linear ser-
vomotor is stopped.
Confirm that the power supply is
correctly wired.
Balance the power supply by chang-
ing phases.
Match the parameter setting to the
power supply.
Turn the power supply OFF and
then ON again. If the alarm still
occurs, the SERVOPACK may be
faulty. Replace the SERVOPACK.
Insert securely the connector or
replace the cable.
Keep the digital operator or the
cable away from noise sources.
