Description Cause Corrective action
Ethernet physical layer link not
established
The Ethernet cable used for
Ethernet communications is
broken or the specified cable
is not being used.
If the Ethernet cable is broken or if the speci-
fied cable is not being used, replace the cable.
Disconnected connector on
the Ethernet cable used for
Ethernet communications,
contact failure, or part failure
Reconnect the connector and check to ensure
it is mated correctly
.
Power is not supplied to the
Ethernet switch connected to
the CPU Unit.
Supply power to the Ethernet switch.
Failure of device within Ether-
net network configuration
Replace the device.
Noise Check noise entry paths, and implement
noise-related countermeasures as required.
CPU Unit failure Replace the CPU Unit.
Interrupted communications
between Power PMAC IDE
and CPU Unit
Communications interruption,
due to disconnection and re-
connection of the Ethernet
cable used for Ethernet com-
munication between Power
PMAC IDE and the CPU Unit
while communication was be-
ing established
If communications are interrupted between
Power PMAC IDE and the CPU Unit with
Ethernet communications established, com-
munications cannot be reestablished simply
by rectifying the problem that interrupted the
communications. T
o reestablish the communi-
cations, you need to click Communication
Setup in Power PMAC IDE and restart com-
munications.
Communications interruption
due to power to Ethernet
switch between Power PMAC
IDE and CPU Unit being
turned OFF → ON while
communications were being
established
Communications interruption
due to power to CPU Unit be-
ing turned OFF → ON while
communications were being
established
Temporary communications
interruption due to noise
Check noise entry paths, and implement
noise-related countermeasures as required.
Then reestablish communications between
Power PMAC IDE and the CPU Unit.
T
o reestablish the communications, you need
to restart Power PMAC IDE or reestablish the
communications by using Power PMAC IDE.
DA output, DirectPWM output
and encoder power supply
from CK3W
-AX Unit not output
Power Supply Unit other than
CK3W-PD048 is being used.
Check the Power Supply Unit model.
CK3W-AX Unit failure Replace the CK3W-AX Unit.
Internal 24 V power is not be-
ing input to the CK3W
-AX
Unit due to a failure of the
Unit to its left.
Replace the Unit to the left of this Unit.
