SAFETY PRECAUTIONS
The control system that is explained in this manual contains various electric components
and units. Please read this manual thoroughly and understand the electric wiring among
the electric components, units, and power supply to avoid unexpected bodily injuries and
malfunction or burnout of the electric components and units.
(1) Always turn off all the power supplies and discharge the electric charge
remaining inside the system before connecting or disconnecting the units. Failure
to follow this instruction may result in electric shock or other bodily injury as well
as malfunction or burnout of the units.
(2) Check the specifications of the power supply to be connected to the units.
Incorrect voltage or electrical polarity may cause unit malfunction or burnout.
(3) Check the inlet connections and outlet connections of all the units. Incorrect
connection may cause unit malfunction or burnout.
(4) Always connect the earth wires as well as the PE wires for the magnetic power
cabinet. Failure to follow this instruction may result in electric shock or other
bodily injury due to an earth leakage.
(5) Set the overcurrent protective device such as circuit breakers or fuses. Failure to
follow this instruction may result in fire or burnout of cables and units due to a
short circuit.
(6) If you make the cables to connect the units by yourself, always use the cable of
the size appropriate for load current especially for power cables. Insufficient
current capacity may cause a fire or burnout of the cables due to overheating.
(7) Select the dust-repellent water-proof type of magnetic power cabinet or control
box that houses various units. Dust or water may cause electric shock or other
bodily injury as well as the unit malfunction or burnout.
(8) Always use thermostats which are built-in the motors and units to protect the
mechanical device. Failure to follow this instruction may cause a fire or units
burnout.
Following caution signs are used in this manual to draw attention to information of
particular importance.
This sign is to indicate an imminently hazardous situation which, if not avoided,

will result in death or serious injury.
This sign is to indicate a potentially hazardous situation which, if not avoided,

could result in death or serious injury.
This sign is to indicate a potentially hazardous situation which, if not avoided,

may result in minor or moderate injury or property damages.
This sign is to indicate general instructions for safe operation.
Keep this manual handy for reference.

Information in this document is subject to change without notice due to constant
improvements.

About step 1
Before disconnecting the motor and power wires, turn off the power, and
make sure that the DC CHARGE LED is turned off. Failure to follow this
instruction will result in an electric shock.
About step 6
Properly set the switches and the jumper connector. The servo motor will
malfunction (will be demagnetized) if it is energized with an incorrect

APPENDIX 1 DESCRIPTION OF MONITOR TERMINALS
APPENDIX 1 DESCRIPTION OF MONITOR TERMINALS
The waveform of the BLIV-D drive unit can be observed by connecting an oscilloscope to
the monitor terminals. This is the same function as conventional units (BLII-D Type A).
For details, see the "Drive Unit BLII-D, VAC II, VA III Maintenance Manual".

APPENDIX 2 SWITCH AND JUMPER CONNECTOR SETTINGS
BLIV-D Type A units have the different number and layout of switches from the
conventional units (BLII-D Type A). Also it is provided with jumper connectors (excluding
BLIV-D200A) that the conventional units do not have. These must be set
(connected/disconnected) according to the capacity of the unit to be used.
The setting of switches and jumper connectors is shown below.
