and turn the power supply OFF and
then ON again.
A.EA2:
DRV Alarm 2
(SERVOPACK WDC
error)
The timing of synchronization
between the servomotor 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
processing 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.
