8.1.2 Troubleshooting of Alarms
8-22
A.E75:
Unsupported
Feedback Option
Module
A feedback option module fault
occurred.
–
Replace the feedback option mod-
ule.
A unsupported feedback option
module was connected.
Refer to the catalog of the con-
nected feedback option module or
the manual of the SERVOPACK.
Connect a compatible feedback
option module.
A.E80:
Command Option
Module Unmatched
Error
The command option module was
replaced with a different model.
–
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.
A.EA2:
DRV Alarm 2
(SERVOPACK WDC
error)
The timing of synchronization
between the SERVOPACK and
command option module changed
due to change in the communica-
tions cycle of the host controller
connected to the command option
module. –
Turn the power supply OFF and
then ON again. If the alarm occurs
again, restart communications pro-
cessing from the host controller.
The connection between the
SERVOPACK and the command
option module is faulty. Check the connection between the
SERVOPACK and the command
option module.
Correctly connect the command
option module.
A command option module fault
occurred.
−
Replace the command option mod-
ule.
A SERVOPACK fault occurred. − Replace the SERVOPACK.
A.Eb1:
Safety Function Signal
Input Timing Error
The lag between activations of
the input signals /HWBB1 and
/HWBB2 for the HWBB function
is 10 seconds or more.
Measure the time lag between the
/HWBB1 and /HWBB2 signals.
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.
A.ED1:
Command Option
Module IF Command
Timeout Error
Processing of the sensor ON
command from the command
option module is not completed.
−
Input a servo ON command when
the linear servomotor is stopped.
Processing of the sensor ON
command from the command
option module is not completed.
−
Check that the linear scale is con-
nected correctly and input a sensor
ON command when the linear ser-
vomotor is stopped.
A.F10:
Main Circuit Cable
Open Phase
(With the main power
supply ON, voltage was
low for more than 1 sec-
ond in an R, S, or T
phase.)
(Detected when the main
power supply was turned
ON.)
The three-phase power supply
wiring is incorrect.
Check the power supply wiring.
Confirm that the power supply is
correctly wired.
The three-phase power supply is
unbalanced. Measure the voltage at each phase
of the three-phase power supply. Balance the power supply by chang-
ing phases.
A single-phase power is input
without setting Pn00B.2 (power
supply method for three-phase
SERVOPACK) to 1 (single-phase
power supply).
Check the power supply and the
parameter setting. Match the parameter setting to the
power supply.
A SERVOPACK fault occurred. −
Turn the power supply OFF and
then ON again. If the alarm still
occurs, the SERVOPACK may be
faulty. Replace the SERVOPACK.
