Synchronization error (in
operation)
After checking the following items,
restart the Slave Unit according to
the specification of connected
EtherCAT Master Unit.
•
Is the communications cable
wired correctly?
•
Is the communications cable
exposed to excessive noise?
If this does not improve, the Slave
Unit hardware may be damaged.
Replace the applicable Slave Unit.

Errors Unique to E3NW-ECT
Symptom
Cause
Measures
Some functions are not reflected
even after parameters have been
set.
The functions enabled by recycling
the power were changed.
Turn ON Slave Unit power supply
again after changing the setting.
The Sensor Amplifier is turned ON
but there is no input.
There is a communications error.
Check the connected number of
sensors.
The SS indicator is lit red.
See below.
SS LED lights red
Number of sensors setting is
different from Number of
connecting sensors
Check the connected number of
sensors.
When use dummy sensor setting,
Set number of sensors setting as
include dummy sensors.
Amplifier connecting is wrong,
Check the connecting of
E3NW-ECT and amplifiers.
If there is vibration or other
movement, use end plates on
Amplifier Units. Make sure the hole
for optical communications is not
blocked.
The connected Sensor Amplifier
Units failed. Replace with the Units.
There is an error in the connections
