Master Unit.
[Item about
communication cable]
•
Is the
communications
cable wired correctly?
•
Are any cables
disconnected or loose
in the part that
connects to the
connector?
•
Is the cable length
appropriate?

specification range?
•
Is the power supply
capacity sufficient?
Malfunction due to
noise
•
If there are devices in
the vicinity that
generate noise, take
necessary measures
against the noise to
protect the EtherCAT
Master Unit and Slave
Units and the
communications
cable.
•
The noise resistance
deteriorates if a cable
other than those of
the recommended
specification is used.
Use the
communications
cable of the
