12-5-2 Troubleshooting during PCU Operations
The following troubleshooting flowchart is for problems that occur after the
PCU has been started (RUN indicator is lit).
Use this flowchart to determine whether the error is a CPU Unit error, a set-
ting or usage problem, or a MECHATROLINK communications error.

An error has occurred while the PCU
is operating.
RUN indicator: Lit
Is the ERH indicator lit?
Is the ERC indicator lit?
Is the ERC indicator
flashing?
Is the MLK indicator lit?
Is the CONNECT Bit in the
Common Operating Memory
Area turned ON?
Are the axis communications status flags
in the Common Operating Memory Area
turned ON?
Is the corresponding axis
registered in the scan list in the
Common Parameters?
Bit for relative axis = 0 in Axes to
Connect parameter?
Turn ON the
CONNECT Bit in
the Common
Parameters and
start
MECHATROLINK
communications.
The axis is not
registered in the scan
list in the PCU's
Common Parameters.
Register the axes
being used in the scan
list, and save the
settings in the PCU's
internal flash memory.
Then restart the Unit
or cycle the power and
execute CONNECT
again. Correct the scan list
settings in the PCU's
Common Parameters.
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.
Set the Axis
Operating Memory
Areas correctly and
then restart the
Position Control Unit.
Axis operation is not
possible if nothing is
specified in the
settings of the Axis
Operating Output
Memory Area.
Check the outputs
from the user
program to see if they
function correctly.
If there is no problem
in the user program,
the probable cause is
a MECHATROLINK
slave station device
malfunction. Replace
the slave station
device and turn ON
the power again.
With Position Control Units
with unit version 2.0 or
later, all axes with the
corresponding bit turned
ON in the Axes to Connect
parameter will not be
included in the connection
even if they are registered
in the scan list.
Confirm equipment safety,
and then turn ON the
corresponding bit and
execute CONNECT again.
The scan list may not
be enabled. To enable
the scan list, save it in
the flash memory in
the Position Control
Unit and then either
restart the Unit or
cycle the power
supply.
If the problem recurs,
the Position Control
Unit may be faulty.
Replace the Position
Control Unit.
Axis Operating Memory Areas in
Common Parameters set correctly?
SERVO
UNLOCK, DEVIATION
COUNTER RESET, EMERGENCY STOP, or
DECELERATION STOP bit
ON?
