Application precautions

WARNING
Do not start the system until you check that the axes are present
and of the correct type.
The numbers of the Flexible axes will change if
MECHATROLINK-II network errors occur during start-up or if the
MECHATROLINK-II network configuration changes.
Not doing so may result in unexpected operation.
WARNING
Check the user program for proper execution before actually run-
ning it in the Unit.
Not checking the program may result in an unexpected operation.
WARNING
AXIS_OFFSET is fixed to a unit number. Changing the position of
the attached units can therefore result in a different axis allocation.
This can result in serious injury and/or significant damage.
HARDWARE REFERENCE MANUAL
WARNING
Always connect the EtherCAT master port to the IN port of the first
slave. Not doing so can result in unreliable communication and
changes to address and axes assignment of EtherCAT slaves.
WARNING
Do not swap connections between the IN and OUT port of Ether-
CAT slaves. This can result in changes of address and axes
assignment of EtherCAT slaves.
WARNING
Do not connect or disconnect EtherCAT slaves while the system is
operational. Doing so can result in unreliable communication.
Caution
Always use the power supply voltage specified in this manual.
An incorrect voltage may result in malfunction or burning.
Caution
Take appropriate measures to ensure that the specified power with
the rated voltage and frequency is supplied. Be particularly careful
in places where the power supply is unstable.
An incorrect power supply may result in malfunction.
Caution
Install external breakers and take other safety measures against
short-circuiting in external wiring.
Insufficient safety measures against short-circuiting may result in
burning.
