Precautions for use
zRegeneration energy
When using the motor in operation such as vertical drive (gravitational operation) or
sudden starting/stopping of an inertial load, regeneration energy may generate. Since
the driver has no function to consume regeneration energy, if the output capacity or
overvoltage allowance of the DC power supply is small, the protective function for
the power supply or driver may activate, and the motor may stop. When performing
these operations, use a DC power supply or battery that has a large output capacity or
overvoltage allowance.
Also, use an electromagnetic brake motor not to drop the moving part in vertical drive
(gravitational operation).
If the protective function for the power supply or driver is activated, contact your nearest
Oriental Motor sales oce.
zDo not conduct the insulation resistance measurement or dielectric
strength test with the motor and driver connected
Conducting the insulation resistance measurement or dielectric strength test with the
motor and driver connected may result in damage to the product.
zDo not use a solid-state relay (SSR) to turn on/o the power
A circuit that turns on/o the power via a solid-state relay (SSR) may damage the motor
and driver.
zNotes for power ON/OFF using a mechanical contact
When turning on or o the power supply using a mechanical contact (breaker,
electromagnetic switch, relay, etc.), do so only the positive side (+) of the power supply
using the mechanical contact. Turning on or o the positive side (+) and the negative side (-)
of the power supply simultaneously using a mechanical contact may cause damage to the
control circuit or peripheral equipment.
Refer to USER MANUAL (Basic Function) for details.
zNote on connecting a power supply whose positive terminal is grounded
The driver's main power supply input terminal (CN1), I/O signal connector (CN4),
communication connector (CN5/CN6/CN7) and control power supply input terminal (TB1)
are not electrically insulated.
When grounding the positive terminal of the power supply, do not connect any equipment
(PC, etc.) whose negative terminal is grounded. Doing so may cause the driver and these
equipment to short, damaging both.
zPreventing electrical noise
Refer to USER MANUAL (Basic Function) for measures with regard to noise.
zGrease measures
On rare occasions, grease may ooze out from the gearhead. If there is concern over
possible environmental damage resulting from the leakage of grease, check for grease
stains during regular inspections.
Alternatively, install an oil pan or other device to prevent leakage from causing further
damage. Oil leakage may lead to problems in the customer’s equipment or products.
zNote on using in low temperature environment
When an ambient temperature is low, a load torque may increase due to the oil seal
or viscosity of grease used in the gearhead, and the output torque may decrease or an
overload alarm may generate. However, as time passes, the oil seal or grease is warmed up,
and the motor can be operated without generating the overload alarm.
zApply grease to the output shaft of a hollow shaft at gearhead
If you are using a hollow shaft at gearhead, apply grease (molybdenum disulde grease,
etc.) on the surface of the load shaft and inner walls of the hollow output shaft to prevent
seizure.
zThe driver uses semiconductor elements. Handle the driver with care
The driver uses parts that are sensitive to electrostatic charge. Before touching the driver,
turn o the power to prevent electrostatic charge from generating. If an electrostatic
charge is impressed on the driver, the driver may be damaged.
zConnecting the motor and driver
For the BLV510 product, be sure to use the included connection cable to connect the motor
and driver.
For the BLV620 and BLV640 products, use the included connection cable to extend the
wiring distance between the motor and driver.
zSliding noise of electromagnetic brake
An electromagnetic brake motor may cause a sliding noise of the brake disk during
operation. There is no functional problem.

Installing the driver
The driver is designed so that heat is dissipated via air convection and conduction through
the enclosure. Install the driver to a at metal plate oering excellent vibration resistance.
When two or more drivers are to be installed side by side, provide at least 20 mm (0.79 in.)
and 25 mm (0.98 in.) clearances in the horizontal and vertical directions, respectively.
Note
Install the driver in an enclosure whose pollution degree is 2 or better
environment, or whose degree of protection is IP54 minimum.
Do not cover the radiation vent of the driver.
Do not install any equipment that generates a large amount of heat or noise
near the driver.
If the ambient temperature of the driver exceeds 40 °C (104 °F), revise the
ventilation condition or force-cool the area around the driver using a fan.
zInstalling with screws
