Precautions for use
−6−
3 Precautions for use
This section covers restrictions and requirements the user should consider when using the BLV Series.
•Regeneration energy
When the motor is used in operation such as vertical drive (gravitational operation) or sudden accelerating/
decelerating of an inertia body, 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 be activated to stop the motor. 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 type motor because there is a risk of falling the moving part in vertical drive such
as elevating equipment.
If the protective function for the power supply or driver is activated, contact your nearest Oriental Motor sales oce.
•Do 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.
•Do not use a solid-state relay (SSR) to turn on or o the power supply.
A circuit that turns on or o the power supply via a solid-state relay (SSR) may damage the motor and driver.
•Notes 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 p.24 for details.
•Note on connecting a power supply whose positive terminal is grounded
The main power supply input terminal (CN1), I/O signal connector (CN4), communication connectors (CN5/CN6/CN7),
and control power supply input terminal (TB1) of the driver 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.
•Grease measures
On rare occasions, grease may ooze out from the gearhead. If there is concern over possible environmental
contamination resulting from the leakage of grease, check for grease stains during regular inspections. Alternatively,
install an oil pan or other device to prevent damage resulting from contamination. Grease leakage may lead to
problems in the user’s equipment or products.
•Note 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 be generated. However, as time passes, the
oil seal or grease is warmed up, and the motor can be driven without generating an overload alarm.
•Apply grease to the hollow output shaft of a hollow shaft at gearhead.
When 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.
•The driver uses semiconductor components. So be extremely careful when handling them.
The driver uses components 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.
•Connecting 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.
•Sliding noise of electromagnetic brake
The electromagnetic brake motor may cause sliding noise of the brake disk during operation.
There is no functional problem.

Precautions for use
−7−
 Noise elimination measures
The electrical noise is of two types: One is a noise to invade into the driver from the outside and cause the driver
malfunction, and the other is a noise to emit from the driver and cause peripheral equipment malfunction.
For the noise that is invaded from the outside, take measures to prevent the driver malfunction. It is needed to take
adequate measures because signal lines are very likely to be aected by the noise.
For the noise that is emitted from the driver, take measures to suppress it.
Refer to p.21 for "Installing and wiring in compliance with EMC Directive."
Measures against electrical noise
There are the following three methods mainly to take measures against the electrical noise.
•Noise suppression
•When relays or electromagnetic switches are used, use noise lters or CR circuits to suppress surge generated by
them.
•Use the connection cable for the exclusive use of the BLV series when extending the wiring distance between the
motor and driver. This is eective in suppressing the electrical noise emitted from the motor.
•Cover the driver by a metal plate such as aluminum. This is eective in shielding the electrical noise emitted from
the driver.
•Prevention of noise propagation
•Separate power lines such as motor cable and power supply cable from signal lines for a distance of 100 mm (3.94in.)
or more, and also do not bundle them or wire them in parallel. If the power lines must cross over the signal lines,
wire them at right angles.
•For more eective elimination of noise, use a shielded I/O signal cable or attach ferrite cores if a non-shielded cable
is used.
•Keep cables as short as possible without coiling and bundling extra lengths.
•To ground a shielded cable, use a metal cable clamp that can maintain
contact with the entire circumference of the shielded cable, and ground
as near the product as possible.
Cable clamp
Shielded cable
•Grounding multiple points will increase eect to block electrical noise because impedance on the grounding points
is decreased. However, ground them so that a potential dierence does not occur among the grounding points.
•Suppression of eect by noise propagation
•Loop the noise propagated cable around a ferrite core. Doing so will prevent the propagated noise invades into the
driver or emits from the driver. The frequency band in which an eect by the ferrite core can be seen is generally
1MHz or more.
Check the frequency characteristics of the ferrite core used. When increasing the eect of noise attenuation by the
ferrite core, loop the cable a lot.

at section to rmly secure the load and prevent it from spinning.
[How to install a load]
•Using a coupling
Align the centerline of the output shaft of the motor or gearhead with the centerline of the load shaft.
•Using a belt
Adjust the output shaft of the motor or gearhead to lie parallel with the load shaft, and form right angles between the
output shaft/load shaft and the line connecting the centers of both pulleys.
•Using a gear drive
Adjust the output shaft of the motor or gearhead to lie parallel with the gear shaft, and allow the output shaft to
mesh correctly with the centers of the gear teeth.
•When using the output shaft end tapped hole of a gearhead
Use a screw hole [M6; Eective depth 12 mm (0.47 in)] provided at the
end of the output shaft as an auxiliary means for preventing the transfer
mechanism from disengaging.
