Message
Probable cause
Remedy
The connected unit is not a Position Control
Unit.
The connected Unit is not the
CJ1W-NCF71 or CS1W-NCF71.
Check whether the connected Unit is
the CJ1W-NCF71 or CS1W-NCF71.
The Unit No. is not correct.
Change the Unit No. either in the Unit
or in the CX-Motion-NCF.
Axis types in NC Unit and CX-Motion-NCF
tool are different. The operation cannot be
continued.
The model (i.e., axis type) set in
the CX-Motion-NCF is different
from the model of the Position
Control Unit.
Change the axis type of the Position
Control Unit.
The MECHATROLINK slave station device
corresponding to the axis number regis-
tered in the Position Control Unit scan list is
not connected.
Check whether the settings for the MECHA-
TROLINK communications line connection
or slave device's station address match the
settings in the scan list, and then execute
CONNECT again.
The axis map (scan list) does not
match with the actual configuration
of the Servo Drives.
Add or delete axes appropriately in the
Axis Map Setting Window, set appropri-
ate axis numbers, and transfer the axis
map to the Unit. Otherwise, change the
axis numbers in the Servo Drives
appropriately.
Cannot start communications with the Posi-
tion Control Unit. Check the Unit No. of the
Position Control Unit.
The Unit No. is not correct, or the
Unit corresponding to the Unit No.
does not exist.
Check the Unit No. of the Position Con-
trol Unit.
Communications with the Position
Control Unit could not be estab-
lished because the I/O table has
not been created.
Create the I/O table.
Stop communications. The Position Control
Unit is busy.
Data could not be transferred from
the CX-Motion-NCF because
parameters were being transferred
from the ladder program.
Stop parameter transfer from the lad-
der program first, and then transfer
data from the CX-Motion-NCF.
Stop communications. The axis
@@
is busy. Data could not be transferred from
the CX-Motion-NCF because
parameters were being transferred
from the ladder program.
Stop parameter transfer from the lad-
der program first, and then transfer
data from the CX-Motion-NCF.
An error has occurred in the Servo Drive of
axis
@@
.
Check the error of the Servo Drive and
remove the cause.
Check if the parameters not supported by
the Servo Drive or out of setting range are
transferred.
• Transferring data caused an error
in the Servo Drive.
• An error occurred in the Servo
Drive during transfer.
Check the error code and provide
appropriate remedy to clear the error.
Clearing the error log failed. Connection
has been established.
MECHATROLINK communica-
tions have been established.
Stop the communications (i.e., release
the connection).
Transferring Servo Parameters failed. An
error has occurred on axis
@@
.
An error has occurred in the Servo
Drive.
Check the error code and provide
appropriate remedy to clear the error.
Could not acquire access right. Another
user is currently occupying the Unit.
The Position Control Unit is being
operated from another personal
computer.
Stop any online operations from
another personal computer.
Cannot connect to the Position Control Unit.
Check the following items.
• Whether the PLC has been turned ON.
• Whether the connection cable has not
been disconnected.
The PLC has not been turned ON. Turn ON the PLC.
The cable between the PLC and
personal computer has been dis-
connected.
Check the connection of the cable.
Communications failed midway
due to noise, etc.
Execute the online operation again.
MECHATROLINK communica-
tions failed due to noise or other
cause during execution of the
absolute encoder setup operation.
Check the connections of the MECHA-
TROLINK communications cable.
