Do two or more MECHATROLINK
slave station devices have the same
station number?
Is the power ON for every
MECHATROLINK slave
station device?
Are the MECHATROLINK
communications cables or terminating
resistance loose or disconnected?
Are the communications settings
for every MECHATROLINK slave
station device set to 10 Mbps and
32 bytes?
Do the station addresses of the
MECHATROLINK slave station devices
match the axis numbers registered in
the scan list?
MECHATROLINK
communications are not
being performed
normally due to
disconnections, faulty
contacts, or breaks in the
terminating resistance or
MECHATROLINK
communications cables.
Check the
communications
connection conditions.
Restart the Unit or cycle
the power, and then
execute CONNECT
again to enable the PCU
to recover.
Check the station
number of the
MECHATROLINK
slave station device,
and set a unique
number for each
device.
Restart the Unit or
cycle the power,
and then execute
CONNECT again to
enable the PCU to
recover.
Turn ON the power
to every
MECHATROLINK
slave station device.
Release the
connection and then
execute CONNECT
again to enable the
PCU to recover.
Make sure that the
MECHATROLINK
communications
cables and
terminating
resistance are
inserted securely so
that they are locked.
Release the
connection at the
PCU and then
execute CONNECT
again.
Set the
MECHATROLINK
slave station device
communications
settings to 10 Mbps
and 32 bytes, and
then cycle the
power.
Release the
connection at the
PCU, cycle the
power to the slave
station device, and
then execute
CONNECT again.
Reset the station
number setting switch on
the slave station device
or change the scan list
settings in the PCU's
Common Parameters,
making sure that the
station numbers of the
MECHATROLINK slave
station devices match
the axis numbers
registered in the scan
list.
If the scan list has been
changed, save the
settings in the PCU's
internal flash memory.
Then restart the Unit or
cycle the power and
execute CONNECT
again.
Check that an error
has not occurred in
the
MECHATROLINK
slave station device
that cannot be
cleared.
Example: Servo
Drive encoder
communications
error (A.C9), etc.
